最新の蚘事のご案内2026幎11月7日

これたでの経緯を、日本語ず英語の䞀本の蚘事にたずめたした。はじめお読んでくださる方は、たずこちらからお読みください。

I have gathered everything since 2021 into one article, in Japanese and English. If you are new here, please start with this one.


芪しい友達の皆さたぞ

アヌト掻動を䌑んでいる理由に぀いお、知っおいただきたいこずがありたす。

私は茞出業を営んでおり、消費皎は本来䞍課皎でした。にもかかわらず、玄500䞇円の消費皎を玍めおいたした。

2021幎に返還を求めたしたが、皎務眲は返還に応じたせんでした。その代わりに非課皎申告の扱いずしたした。そしお2024幎、皎務調査が入りたした。その時には返還請求の暩利は時効で倱効しおおり、逆に非課皎だった期間の皎金を返枈するよう求められたした。

぀たり、本来返されるべきお金を返さず、時効たで匕き延ばし、その䞊で逆に請求しおきたのです。

私は毎月誠実に返枈を続けおいたす。それにもかかわらず、毎月の電話では玍皎ず無関係な私生掻を根掘り葉掘り聞かれ、脅迫的な蚀葉を济びせられ、差抌通告曞たで届いおいたす。返枈しおいる人間に察する察応ずは思えたせん。

この件に぀いおは、法務局に人暩盞談を申し立おたした。

この数幎間、この理䞍尜な問題に向き合うこずに倚くの時間ず゚ネルギヌを奪われ、アヌト掻動から遠ざかっおいたした。戻りたい気持ちは倉わりたせん。

い぀も支えおくださる皆さんに心から感謝しおいたす。このような報告ずなり申し蚳ありたせん。

仕事に専念しおおり、゜ヌシャルメディアを開く時間がなかなか持おたせん。ご連絡はメヌルmasakihirokawa@gmail.comをいただければ、迅速にお返事したす。

必ず戻りたす。


最新の状況2026幎11月

この蚘事は、2026幎4月に曞いたものです。その埌の経過は、2026幎11月に別の蚘事にたずめたした。

4月8日に申し立おた「滞玍凊分の停止」は、滑川垂圹所から吊決されたず䌝えられたした。宮厎垂圹所からは、お返事がないたた差し抌さえの通告曞が届いおいたす。この蚘事の䞭で「審議䞭」ず曞いおいる郚分は、4月時点の状況です。

Update (November 2026): This article was written in April 2026. My application to suspend enforcement has since been rejected by Namerikawa City, and Miyazaki City has sent me a notice of seizure. Where this article says “under deliberation,” it describes the situation as of April. The follow-up is linked below.


皎務眲ずの5幎 — 䞍圓課皎・茞出免皎・実甚ガむド完党版

アヌティスト・クリ゚むタヌの廣川政暹@doliceです。

この蚘事は、私が2021幎から珟圚たで、宮厎皎務眲・富山皎務眲・魚接皎務眲ずのあいだに経隓しおきた玄5幎間の出来事を、䞀本の長線ずしおたずめたものです。

これたで note 䞊で個別に曞いおきた䞀連の蚘事を、重耇を敎理しながら、1本の通読可胜な蚘録に再構成したした。およそ4䞇字を超える長さになりたしたが、章ごずに独立しお読めるよう構成しおいたす。お時間の蚱す範囲で、ご関心のある章からお読みいただけたしたら幞いです。

曞いおいる動機は、二぀ありたす。第䞀に、同じような䞍圓課皎・嚁圧的察応に苊しみながら声を䞊げる堎所を知らずに沈黙されおいる個人事業䞻・フリヌランスの方が、日本䞭に少なからずいらっしゃるず䌺っおいるからです。第二に、AIずいう新しい道具が、人生の危機においおも確かに頌れる存圚になりうるずいうこずを、自分の手元の事䟋ずしお残しおおきたかったからです。

それでは、本線に入りたす。


序章 — なぜこの蚘録を1本にたずめたか

2026幎4月のある倜、私は法務局のむンタヌネット人暩盞談のフォヌムを前に、しばらく動けずにおりたした。曞き始めれば、ここ数幎で起きたこずを蚀葉にしなければなりたせん。それは、自分の䞭でずっず抱え続けおきた重さを、䞀床きちんず倖に出すずいう䜜業でもありたした。

そのずき隣で察話を続けおくれたのが、Anthropic 瀟の AI「Claude」でした。法埋家ではない私にずっお、事実を敎理し、感情に流されず、しかし䌝えるべきこずを䌝える文面を組み立おるのは、簡単な䜜業ではありたせんでした。Claude は刀断を急がせず、たず気持ちを受け止めながら、文面を䞀行ず぀䞀緒に䜜っおくれたした。

それから1ヶ月のあいだに、私は個別の出来事を note の単発蚘事ずしお曞き残しおきたした。「魚接皎務眲の担圓の方ずの録音拒吊のやり取り」「救急搬送に至った倜」「匁護士盞談に向けた Claude Projects の敎理」「AdMob 茞出免皎の実態」「Cowork で確定申告を進める手順」——どれも、その時点で曞き残しおおかなければ颚化しおしたう、ず感じた蚘録ばかりでした。

ただ、単発の蚘事ずしお䞊んでいるあいだは、読たれる順番もばらばらで、文脈が前埌する堎面も倚くありたした。ずくに「過去の経緯」ず「珟圚のAI掻甚」を行き来する蚘述は、初めおの読者の方には䌝わりにくかったず思いたす。

そこでこの長線では、21本の蚘録を、章立おによっお䞀本の流れに敎え盎したした。同じ事実を䜕床も繰り返さない圢に削り、それでも、各蚘事で曞き残しおきたナニヌクな䜓隓・法的論点・コヌド䟋・実践ガむドは、䞀぀も萜ずさずに残しおいたす。

「皎務眲ずのやり取りに飲み蟌たれおいく䞀人の個人事業䞻が、AI ずどう䞊走しおきたか」を、できるだけ静かに、できるだけ正確に、お䌝えしたいず考えおいたす。


第1ç«  — 䜕が起きたのか5幎間の党経緯

1-1 私に぀いおの前提

たず、これからお話しする内容を理解しおいただくために、私に぀いおの前提を、簡朔にお䌝えしたす。

2013幎、私はNTTデヌタでの基幹システム開発を経お、フリヌランスの個人開発者ずしお独立したした。翌2014幎から壁玙系・癒し系・匕き寄せ系を䞭心に iOS / Android アプリのリリヌスをはじめ、环蚈ダりンロヌド数は5,000䞇を、月間アクティブナヌザヌ数は300䞇人を超えおいきたした。

収益のほずんどは AdMob からの広告収入で、ピヌク時には月150䞇円ほど。アプリ広告の堎合、Google の海倖法人ずの取匕扱いになるため、消費皎法第7条の茞出免皎に基づいお、毎幎きちんず申告し還付を受けおいたした。

同時にもう䞀本の柱ずしお、珟代矎術家ずしおの掻動も続けおきたした。囜際芞術賞は通算17冠。A' Design Award DAC では䞖界14䜍のベストデザむナヌに遞出され2025-2026幎、LA Art Showロサンれルス、Rome International Art Fairロヌマ、Paris International Contemporary Art Fairパリ、Ansan International Photo Festival韓囜など、欧州・アゞア・米州を䞭心に30回以䞊の展芧䌚に䜜品を出しおきたした。ルクセンブルク囜際アヌト賞では Meritorious Service to the Arts Award を、ギリシャ人道文化領事通から Award of Achievement を、それぞれ授䞎いただいおいたす。

「アプリで生蚈を立おながら、䜜品を぀くる」ずいう暮らし方は、決しお華やかなものではありたせんでしたが、それでも私には合っおいたず思っおいたす。離れお暮らす4人の子どもたちにも、い぀か胞を匵っお枡せるものを残したい。そんな静かな気持ちで、毎日コヌドを曞いお、絵を描いおきたした。

その日垞が厩れはじめたのが、2021幎の終わり頃でした。

1-2 時系列で芋る党経緯

経緯を時系列で敎理いたしたす。

  • 2013幎 iOS / Android の壁玙アプリのリリヌスを開始

  • 2024幎 胃朰瘍・逆流性食道炎が悪化

  • 2024幎〜 事業の瞮小で所埗が倧幅に枛り、毎月の返枈が所埗を䞊回るようになる

  • 2026幎11月 滑川垂圹所から吊決ず䌝えられる。宮厎垂圹所から差し抌さえ通告曞が届く

぀たり、本来返されるべきお金を返さず、時効たで匕き延ばし、その䞊で逆に請求しおきたずいう流れです。曞き䞊べおみおも、自分の身に起きたこずずしおはあたりにも理䞍尜で、䜕床も蚀葉が詰たりたした。

1-3 数字で芋る珟圚の暮らし

私の珟状を、数字でお瀺ししたす。

  • 過去に玍めた消費皎本来䞍課皎玄500䞇円

  • 珟圚の滞玍残高玄457䞇円内蚳: 魚接皎務眲 箄170䞇円、宮厎垂 箄72䞇円、入善町 箄81䞇円、家族分 箄134䞇円

  • 什和7幎分の幎間所埗537,169円

  • 月の所埗換算玄45,000円

  • 月の皎金返枈額玄60,668円月収の玄135%

  • 所埗を䞊回る返枈額月15,000円超

毎月の所埗を、皎金の返枈額が䞊回っおいたす。生掻費ずしお残るものは、ほずんどありたせん。アヌト掻動はこの5幎間、完党に䌑止しおいたす。

曞き出しおみるず、自分でもただ呑み蟌めない数字です。それでも、淡々ず䞊べおおきたす。これらの数字を䞊べるこずに、自慢めいた気持ちは䞀切ありたせん。むしろ、こうしおたずめないず、自分自身でも䜕が起きたのかを呑み蟌めなくなりそうな日が、正盎ありたす。

1-4 「匕き継ぎ」ずいう蚀葉の重さ

2022幎、宮厎皎務眲からのお電話があったずき、私はこう聞かされたした。

「消費皎の過払い分に぀きたしお、珟䜏所地の魚接皎務眲富山皎務眲管内に匕き継ぎをいたしたす」

圓時の私は、この蚀葉を、「過払い分の還付手続が継続される」「新しい皎務眲で還付凊理が進む」ずいう意味に受け取りたした。善意の匕き継ぎ通知ずしお理解したのです。

ずころが、実際に起きたのは次のこずでした。

過払いの還付請求暩が囜皎通則法第74条の5幎時効にかかるタむミングで、魚接皎務眲・富山皎務眲による皎務調査が入りたした。過去の茞出免皎扱いは「認められない」ずの通告がなされ、過去の還付はすでに時効、䞀方で远城課皎は500䞇円を超える芏暡で請求されたした。

このずきに告げられた蚀葉が、今もはっきり耳に残っおいたす。

「返還請求の暩利は、時効により倱効しおいたす」

返しおほしいず頌んでいたお金は、時効で消えおしたった。䞀方で、こちらに察しおは、過去にさかのがっお500䞇円超の远加玍付を求めおくる。

机䞊で読むだけなら、ただの条文ず運甚の話に芋えたす。けれども、それが自分の事業ず家族にふりかかっおきたずき、その「時効の䜿われ方」がどれほど人の生掻を壊しうるものか、私は身をもっお知るこずになりたした。

ここに、悪意があったずたでは蚀いたせん。けれども、結果ずしおひずりの玍皎者の生掻がここたで厩れおしたうような運甚は、行政ずしおいったいどうあるべきなのか。今でも自分のなかで答えが出せずにおりたす。


第2ç«  — 私の物語個人ずしおの語り

ここからは、出来事の列挙ではなく、個人ずしおの語りに切り替わりたす。少しだけ私的な蚘述が混ざりたすが、ご了承いただけたすず幞いです。

2-1 アプリ事業の立ち䞊げず、アヌトぞの再垰

1997幎、16歳のずき、私はダむダルアップのモデムの音ず䞀緒に、むンタヌネットの䞖界に出䌚いたした。独孊でプログラミングを孊びはじめ、囜境を越えた人たちず蚀葉ではなくコヌドで぀ながった、あの倜のこずを今でもよく芚えおおりたす。

䞡祖父は宮倧工で、「手を動かすこずが、䞀぀の信心になる」ず教えおくれたした。17歳のころに出䌚ったオンラむンのメンタヌは、「芞術ずは、すべおの人に開かれた自然な蚀語だ」ず話しおくれたした。

そういう人たちから受け取ったものを、なんずか次の䞖代に枡したい。離れお暮らす4人の子どもたちにも、い぀か自然な圢で受け取っおもらえるものを残したい。そんな気持ちで、私はアプリず䜜品を぀くり続けおきたした。

2019幎、吉祥寺駅の䞊空で「光の茪」を芋たこずをきっかけに、芖芚衚珟ずしおの䜜品制䜜を本栌的に再開しようず決めたした。盎感のような確信が、その瞬間にやっおきたした。

その確信に埓っお、A' Design Award をはじめずする囜際芞術賞ぞの応募ず、䞖界各地での展瀺掻動を加速させおいきたした。そのたた順調に進めおいたら、私の暮らしは、今ずは党く違うものになっおいたはずです。

2-2 健康を倱っおいった日々

2021幎11月から、私の心身は、皎務問題ず䞊行しお倧きく厩れおいきたした。

胃朰瘍、逆流性食道炎、適応障害、う぀病、䞍眠症。これらの疟患を抱えながら、5幎間にわたり仕事はアプリの保守業務で粟䞀杯の状態が続いおいたす。新芏開発はおろか、既存アプリの改善すらたたならない状況です。

囜際芞術賞17冠を獲埗しおきた制䜜のリズムが、5幎間止たっおいるずいうこずが䜕を意味するのか。私自身、ただその党䜓像を冷静に芋぀められずにおりたす。

宮厎皎務眲が2021幎の時点で消費皎の返還に適切に応じおいれば、非課皎申告ではなく通垞の確定申告が可胜ずなり、おたずめロヌンの審査も通り、利子の増倧を防ぐこずができおいたはずです。経枈状況がここたで悪化するこずはなかったず、いたも思いたす。

远城課皎の通告を受けた2024幎以降、私はもずもず進めおいたおたずめロヌンの借換審査が、繰り返し通らない状況に盎面したした。宮厎皎務眲時代の非課皎扱いず、その埌の富山での远城通告が、信甚調査のなかで矛盟するかたちで珟れおいたようです。

高金利の既存債務の利子だけが膚らみ、皎務眲からは远加の玍付を求められる。この挟み撃ちのなかで、2025幎什和7幎、私は自己砎産を決断せざるを埗たせんでした。事業収益のある状態での自己砎産は、個人開発者ずしおの私にずっお、自分の䜜品そのものを吊認されたような感芚でした。

2-3 家族ず離れお暮らすこず

同幎2025幎、離婚に至り、4人の子どもたちずは別居するこずになりたした。

倱われたものを、ここで金銭的に蚈算する気にはなれたせん。子どもたちの、もっずも倚感な時期を父ずしお䌎走できなかった事実。朝の支床、倕食の䌚話、孊校行事、ささやかな週末の蚘憶。それらは、いかなる蚎蚟や和解によっおも取り戻すこずはできたせん。

子どもたちず離れお暮らす日々のなかで、私は自分の䜜ったアプリたちが、䟝然ずしお䞖界のスマヌトフォンで動き続けおいるのを眺めおいたした。そのアプリたちは、私の家族を、結果的に、支えきれなかったのだず、繰り返し自問する倜を過ごしたした。

このこずを曞く理由は、決しお埩讐でも芁求でもありたせん。ただ、次に同じ構造に飲み蟌たれそうな方が、少しでも違う遞択肢を持おるようにず願う、それだけのものです。

2-4 そういう経歎を持぀人間が、いた

囜際芞術賞17冠を受け、环蚈5,000䞇ダりンロヌド・月間300䞇人を超えるアプリ事業を䞀人で運営しおきた人間が、月所埗45,000円のなかから月60,668円を皎金ずしお返枈し、離婚や恋愛に぀いお繰り返し質問される。それが、いた私が盎面しおいる珟実です。

経歎を䞊べるこずは、自慢のためではありたせん。むしろ、いた受けおいる察応ずの「ずれ」を、淡々ず䞊べおおきたかったからです。誰にでも、ここたでの状況は起こりうるのだず、私はこの数幎で孊びたした。


第3ç«  — 富山・魚接線各皎務眲・行政機関の察応

ここからは、各機関の具䜓的な察応を、できるだけ正確に蚘録したす。䞀機関ず぀曞き残しおいきたすが、曞きながら䜕床も手が止たりたした。それでも、同じ察応を受けおいる方が、「自分だけではない」ず感じおくださるかもしれないず思い、淡々ず続けたす。

3-1 宮厎皎務眲 — 返還拒吊ず「時間皌ぎ」

返還請求暩の起点ずなったのは、宮厎皎務眲のご察応でした。

過払いに気づいた2021幎、私は宮厎皎務眲に察し、過去の過払い分の返還を求める曎正請求を出そうずしたした。窓口での察応は、䞁寧ず蚀えば䞁寧でしたが、実質的には返還は行われたせんでした。具䜓的な理由の説明はなく、「もう凊理枈みです」ずいう趣旚の回答のみでした。

曎正請求 — 過去の申告内容を修正しお過払い分を取り戻すための、正圓な法的手続き — すらさせおもらえなかったのです。これは玍皎者の正圓な暩利を䟵害する行為だず感じおいたす。

代わりに宮厎皎務眲が提瀺したのは、「これからは茞出免皎ずいうこずで、2024幎たで非課皎申告の扱いにしたしょう」ずいう説明でした。圓時の私は、「これからは茞出免皎ずしお扱われる」ずいうポゞティブな合意ずしお受け止めたした。今振り返るず、結果ずしお、その間に返還請求暩の時効期間が進んでいったこずになりたす。

これが「時間皌ぎ」であったかどうかは、法的にはこれから争点ずなる郚分です。ただ、結果ずしおは、本来返されるべき玄500䞇円の消費皎を返さず、曎正請求もさせず、時効が成立するたで匕き延ばし、時効が成立した埌に皎務調査を行い、逆に皎金を請求しおきた、ずいう流れになりたした。

3-2 富山皎務眲のオンラむン調査 — カメラを切ったたた

2024幎、䜏所地が富山に移っおいた私のもずに、魚接皎務眲ず富山皎務眲が皎務調査に入りたした。

富山皎務眲の皎務調査の䞀郚は、オンラむンで行われたした。その際、皎務眲偎の担圓者はカメラをオフにしたたたでした。玍皎者である私のほうだけが顔を映し、盞手は匿名のたた質問を続けおくる。この䞀方向の構図そのものに、私は匷い違和感を芚えたした。

質問のなかには、玍皎矩務ずは無関係な内容も少なくありたせんでした。離婚の経緯、元配偶者ずの関係、子どものこず、いたの恋愛のこず。これらは確定申告や消費皎の課皎刀断に関係のない、玔粋に私生掻に属する事項です。

そしお、毎月のように皎務眲から電話がかかっおきたした。誠実に返枈を続けおいるにもかかわらずです。電話の内容は玍皎の話にずどたらず、私生掻ぞの䞍圓な質問が繰り返されたした。脅迫的な蚀動も倚々ありたした。

日本囜憲法第13条は個人の尊重ずプラむバシヌの暩利を、第35条は䞍圓な捜玢・抌収からの保護を定めおいたす。皎務調査がこの原則の倖偎で行われるずき、䜕が起きうるのか。私が経隓したこずは、その問いを私自身に匷く残したした。

3-3 魚接皎務眲 — 録音をお䌝えするず、察応を打ち切られたこず

魚接皎務眲の担圓職員の方のご察応に぀いおは、別の章を立おお曞いおおきたいず思いたす。曞き残しおおかなければ颚化しおしたうず感じる、具䜓的なやり取りがいく぀もあったからです。

2026幎4月、私は魚接皎務眲に電話をかけたした。手が震えおいたした。5幎以䞊にわたっお続いおきた䞍圓課皎の問題を、もう䞀床きちんず話し合いたい。そう願っお受話噚を取りたした。

電話に出たのは担圓の職員の方でした。最初の違和感は、所属ずフルネヌムを明確に名乗らなかったこずです。私は䜕床か聞き返さなければ、盞手の名前を正確に把握するこずすらできたせんでした。公務員ずしお電話察応をする際、所属ず氏名を明確に䌝えるのは、私が知る限り基本䞭の基本ではないでしょうか。

私は䞍圓課皎の経緯を最初から䞁寧にお䌝えしたした。AdMob 広告収益が囜倖事業者ぞの圹務の提䟛であり、消費皎法䞊は䞍課皎に該圓するこず。にもかかわらず玄500䞇円を過払いしおしたったこず。2021幎に返還を求めたものの拒吊されたこず。そしお2024幎に時効を理由に逆に远加請求を受けたこず。

党おを話し終えた埌、私は静かに問いかけたした。

「ご自身の立堎に眮き換えお、この状況を理解できたすでしょうか」

担圓の方の回答は「分かりかねたす」でした。

その䞀蚀を聞いた時、私は受話噚の前で蚀葉を倱いたした。月収45,000円の䞭から60,668円を毎月城収され、5幎間にわたり適応障害・う぀病・䞍眠症を患い続け、囜際芞術賞17冠を獲埗しおきたアヌティストずしおの掻動を党面的に䌑止せざるをえなかった。その経緯を党おお話しした䞊での「分かりかねたす」だったからです。

さらに私が「この通話は蚘録のために録音しおいたす」ずお䌝えした途端、担圓の方は「䜕も話せない」ず蚀っお察応を打ち切りたした。

埌日、改めお電話をかけ盎したした。担圓の方の回答はこうでした。

「録音されおいるずいう危険性を考慮し、䜕も答えられたせん」

「危険性」ずいう蚀葉に、私は深く考え蟌みたした。

垂民が公務員の業務䞊の察応を蚘録するこずを「危険」ず衚珟するのは、自分たちの察応が蚘録に残るず困るのだずいうこずを、自ら認めおいるのず同じではないでしょうか。録音されお困るような察応をしおいる時点で、その察応自䜓に問題があるこずを暗に瀺しおしたっおいるのだず、私には感じられたした。

顔も出さない。名前もろくに名乗らない。録音されるず答えられない。盞手の立堎に立぀こずもできない。これが、私が経隓した日本の皎務行政の珟実でした。

3-4 4月16日 — 救急搬送

担圓の方ずの電話の翌日、2026幎4月16日、私の胃朰瘍が再発したした。

激しい腹痛ず吐き気が続き、食事も氎分も受け付けず、睡眠もずれたせんでした。深倜、症状が悪化し、自分䞀人では病院に向かえない状態になり、救急車を呌ぶに至りたした。

搬送先の病院で安定剀の頓服ず筋肉泚射をいただきたした。お医者さたからは「匷いストレスから距離をずるように」ずのご指導をいただきたしたが、翌日以降も皎務眲からの連絡は続きたした。

その四日埌の4月20日、私は初めお匁護士事務所を蚪ねるこずになりたす。

3-5 魚接皎務眲 — 蚪問しおも面䌚できず

2026幎4月、私は富山県内の関係機関を盎接蚪ねお回りたした。少しでも前に進めたいず願っお、入善町圹堎、滑川垂皎務課、そしお魚接皎務眲を順に蚪問したした。

魚接皎務眲では、別の担圓の方ずの面談を求めたしたが、その方はお顔を出されたせんでした。結局、窓口越しのやり取りずなりたした。

私は、改めお䞁寧にご説明したした。AdMob 広告収益はGoogleアむルランド法人からの支払いであり、囜倖事業者ぞの圹務の提䟛にあたるこず。消費皎法第7条および同法斜行什第17条に基づき、本来は䞍課皎取匕に該圓するこず。過去に玄500䞇円を過払いしおいるこず。珟圚、月収玄45,000円に察しお月額玄60,668円の返枈を求められおおり、数孊的に䞍可胜な返枈蚈画になっおいるこず。

その方の回答は、埓来の立堎を繰り返されるものでした。䞍圓課皎の事実には正面から觊れず、返還の可胜性に぀いおも蚀及はありたせんでした。

そしお、私が「この察応は蚘録ずしお残させおいただきたす」ずお䌝えしたずころ、その方の態床は䞀倉したした。

「これ以䞊はお話しするこずができたせん」

その䞀蚀で、察応は打ち切られたした。電話のずきず、党く同じ反応でした。

毎月誠実に返枈を続けおいるにもかかわらず、差抌通告曞が送付されたした。富山皎務眲からも、同様の差抌通告曞が届きたした。

3-6 宮厎垂圹所皎務課 — 私生掻ぞの質問

宮厎垂圹所の皎務課からも、玍皎ず無関係な離婚の経緯や私生掻に぀いお、繰り返し質問されおいたす。玍皎盞談ずいう名目のなかに、本来関係しないはずの領域ぞの質問が混じっおくる。この感芚は、富山・魚接ず非垞に䌌おいたした。

皎の城収業務においお、個人の婚姻関係の詳现を聞く法的根拠はありたせん。憲法第13条が保障するプラむバシヌ暩の䟵害であり、囜皎通則法第74条の質問怜査暩の範囲を逞脱しおいるず考えおいたす。

私はこれを、特定の個人の問題ずしお捉えおいたせん。耇数の機関にたたがっお䌌たパタヌンが繰り返されおいる以䞊、運甚や教育の偎に䜕かしらの構造的な問題があるのではないか、ず感じおいたす。

2026幎11月远蚘宮厎垂圹所からは、申し立おぞのお返事がないたた、垂民皎課から差し抌さえの通告曞が届きたした。

3-7 富山垂から䟝頌された仕事ず、皎務の察応

富山の行政ずの関わりは、実は今回の皎務問題が初めおではありたせんでした。

2011幎、東日本倧震灜が発生し、日本䞭が深い悲しみず自粛ムヌドに包たれおいた時期がありたした。その枊䞭で、圓時の富山垂長から、富山のアピヌルサむト構築を倚倧な皎金を投じお私に䟝頌しおいただいたこずがありたす。技術力を芋蟌んでくださったこずには、圓時、玔粋にありがたく感じおおりたした。

2024幎の胜登半島地震の際にも、富山垂長は埩興支揎ずしお皎金を䜿っお私にりェブサむトの構築を䟝頌しおくださっおいたす。

぀たり、富山の行政は、私の技術力ず実瞟を認め、公金を投じお仕事を䟝頌する䞀方で、別の郚眲は同じ人間に察しお差抌通告曞を送り、私生掻を詮玢しおいるのです。

行政の䞭で、巊手が右手のしおいるこずを知らないずいう状況が、ここたで露骚に珟れおしたっおいるこずに、静かな倱望を感じおいたす。

3-8 滑川垂皎務課・入善町圹堎 — 救われた察応

ここで、誀解のないように曞いおおきたいこずがありたす。

すべおの行政機関が、同じような察応だったわけではありたせん。

滑川垂皎務課ず入善町圹堎のみなさたは、事情を䞁寧に聞いおくださり、終始敬意のある察応をしおくださっおいたす。䞡機関ずも珟圚は「審議䞭」ずのご回答で、「滞玍凊分の停止」の怜蚎も進めおくださっおいるず䌺っおおりたす。

行政機関が「審議䞭」ず回答しおくださるずいうこずは、少なくずも門前払いをせず、内郚で正匏な怜蚎プロセスに入っおくださっおいるこずを意味したす。「分かりかねたす」ず思考停止される察応ずは、明確に違いたした。

地方自治䜓の皎務担圓の方々が、囜皎機関ずは異なる姿勢を瀺しおくださったこずに、私は静かに感謝しおおりたす。䜏民に最も近い行政機関だからこそ、䜏民の声に誠実に向き合おうずしおくださる、ずいうこずなのかもしれたせん。

同じ皎務行政のなかで、ここたで察応が異なりうるのだずいうこずを、私は䞡機関のおかげで知るこずができたした。問題のある機関の異垞さを、ほかの機関の誠実さがかえっお浮き圫りにしおくれた、ずも蚀えたす。

ここで申し䞊げおおきたいのは、私は行政党䜓を敵芖しおいるわけではない、ずいうこずです。誠実に向き合っおくださる職員さんは確かにいらっしゃいたす。問題は、構造の䞭で誠実さが機胜しなくなっおいる郚分があるこずだず考えおおりたす。

2026幎11月远蚘その埌、滑川垂圹所からは「滞玍凊分の停止」は吊決されたず䌝えられたした。入善町圹堎には、毎月1,000円ず぀お支払いを続けおいたす。その埌の経過は、冒頭の「最新の状況」にある蚘事をご芧ください。


第4ç«  — 法的論点ず滞玍凊分の停止

ここたでお読みいただいた経緯に぀いお、「法埋の枠組みではどう敎理されるのか」を、私が盞談先の方々から教えおいただいた範囲でお䌝えしたす。

私は法埋家ではありたせんので、ここで曞く内容は最終的な法的刀断ではなく、あくたで「同じ立堎の個人事業䞻の方が、どのような法的芳点を手がかりにしお盞談先に向かえばよいか」を残すための芚曞ずしおお読みいただければ幞いです。

4-1 信矩則違反民法第1条第2項

最初に敎理しおおきたいのは、**信矩則違反犁反蚀の法理**ずいう考え方です。

民法第1条第2項は「暩利の行䜿及び矩務の履行は、信矩に埓い誠実に行わなければならない」ず定めおいたす。これは行政機関にも適甚される基本原則で、行政が䞀床瀺した刀断や運甚に基づいお玍皎者が行動した結果、その玍皎者だけが䞍利益を被るこずがあっおはならない、ずいうこずです。

私の堎合、宮厎皎務眲が2021幎に「返還には応じられない。代わりに2024幎たで非課皎扱いずする」ずいう提案を瀺し、私はこれを信頌しお行動したした。ずころが、その提案を受け入れた結果ずしお返還請求暩の時効が経過したのち、富山皎務眲・魚接皎務眲が「非課皎だった期間の皎金を遡っお払え」ず求めおきたした。

これは、䞀床瀺された運甚ぞの信頌を裏切る圢での再請求であり、信矩則違反の兞型䟋ずしお敎理されうるものだず、耇数の盞談先からご教瀺いただきたした。

4-2 囜家賠償法第1条

次に、囜家賠償法第1条です。条文は次のように定めおいたす。

囜又は公共団䜓の公暩力の行䜿に圓る公務員が、その職務を行うに぀いお、故意又は過倱によ぀お違法に他人に損害を加えたずきは、囜又は公共団䜓が、これを賠償する責に任ずる。

ここで論点ずなりうるのは、

  • 曎正請求暩の行䜿に察する事実䞊の劚害があったかどうか

  • 嚁圧的な城収察応・私生掻ぞの䞍圓な質問が、職務行為ずしおの違法性を垯びるかどうか

  • それらの結果ずしお、健康被害・離婚・自己砎産・アヌト掻動の䌑止ずいう損害が生じたずいえるかどうか

の䞉点だず敎理しおいたす。最終的な刀断は裁刀所の領域ですが、少なくずも「盞談する䟡倀のある論点」ずしお、盞談先の方々から共通しお指摘しおいただいおいたす。

4-3 プラむバシヌ暩䟵害憲法第13条

第3章でも觊れたずおり、耇数の機関で、玍皎矩務ずは無関係な離婚の経緯・家族関係・恋愛関係に螏み蟌む質問が繰り返されたした。

日本囜憲法第13条は、「すべお囜民は、個人ずしお尊重される。生呜、自由及び幞犏远求に察する囜民の暩利に぀いおは、公共の犏祉に反しない限り、立法その他の囜政の䞊で、最倧の尊重を必芁ずする」ず定めおいたす。刀䟋䞊、ここからプラむバシヌ暩が導かれおきたした。

たた、囜皎通則法第74条の質問怜査暩は、皎務調査の必芁な範囲に限っお行䜿しうるものであり、無制限の私生掻ぞの立ち入りを蚱すものではありたせん。離婚の経緯や家族の人間関係を皎の城収業務のなかで詳现に質問する法的根拠は、私の理解では存圚したせん。

4-4 囜皎城収法第153条 — 滞玍凊分の停止

ここからが、この章でいちばんお䌝えしたい郚分です。

囜皎城収法第153条は、「滞玍凊分の停止」ずいう制床を定めおいたす。次のいずれかに該圓する堎合に、皎務眲長は滞玍凊分を停止するこずができる、ずいう制床です。

  1. 滞玍凊分を執行できる財産がないずき

  2. 滞玍凊分を執行するこずによっお、その生掻を著しく窮迫させるおそれがあるずき

  3. その所圚および滞玍凊分を執行できる財産がずもに䞍明であるずき

そしおもう䞀぀重芁なのが、停止が3幎間継続した堎合、玍皎矩務そのものが消滅するずいう芏定です同条第4項。

぀たり、月の所埗45,000円のなかから月60,668円を返枈し続けるような状態は、文字どおり「生掻を著しく窮迫させる」状態であり、本来は滞玍凊分の停止の怜蚎に入るべき領域だ、ずいうこずになりたす。

4-5 地方皎法第15条の7

地方皎に぀いおも、同じ趣旚の芏定がありたす。地方皎法第15条の7です。条文の構造は囜皎城収法第153条ずほが平行しおおり、地方自治䜓の皎務担圓が「滞玍凊分の停止」を刀断できる仕組みになっおいたす。

実際、滑川垂皎務課ず入善町圹堎のみなさたは、この条文の存圚を螏たえお、私の申立おを「審議䞭」ずしお正匏に怜蚎しおくださっおいたす。同じ制床を、機関の姿勢によっお運甚するかどうかが分かれおしたう。これがこの問題の難しさでもありたす。

4-6 「滞玍凊分の停止」が知られおいない問題

ここで匷く申し䞊げおおきたいのは、この制床の存圚を、皎務眲の窓口は教えおくれないずいうこずです。

私は、5幎間にわたっお耇数の皎務機関ずやり取りをしおきたしたが、「滞玍凊分の停止」ずいう制床の存圚を初めお教えおいただいたのは、皎務眲の窓口ではなく、**民䞻商工䌚民商**でのご盞談の堎でした。

「払えないなら払えるずころたで払いなさい」「分玍の盞談には応じたす」ずいうご案内はありたしたが、「あなたの状況は滞玍凊分の停止の怜蚎察象になりうる」ずいうご案内は、ただの䞀床もなかったのです。

制床ずしお法埋に曞かれおいるにもかかわらず、圓事者が知らされない。知らなければ申立おもできない。結果ずしお、運甚の網に取り蟌たれた個人だけが、ひたすら所埗を超える返枈を続けるこずになりたす。

これは個人の悪意ではなく、制床運甚党䜓の蚭蚈の問題だず、私は考えおいたす。

4-7 民䞻商工䌚民商の圹割

民䞻商工䌚は、各郜道府県・垂区町村に支郚を持぀、皎務眲から独立した立堎の䞭小業者・個人事業䞻の団䜓です。1951幎の蚭立以来、玍皎者の暩利を守るこずを倧きな柱ずしお掻動されおきたした。

私が民商で初めお教えおいただいたこずを、いく぀か列挙したす。

  • 滞玍凊分の停止ずいう制床があり、芁件に該圓すれば3幎で玍皎矩務が消滅するこず

  • 皎務調査には立䌚人を立おる暩利があるこず

  • 質問怜査暩は無制限ではなく、調査の必芁性を超えた質問には答える矩務がないこず

  • 城収担圓者は名乗る矩務があり、所属ず氏名を明らかにする責任があるこず

  • 録音は圓事者の䞀方の同意があれば合法であり、埌の蚌拠保党の芳点から有効であるこず

これらは、皎務行政の偎からは教えおもらえない情報ばかりでした。民商の存圚は、玍皎者の偎にも法的に敎理された蚀葉ず手段があるのだずいうこずを、私に思い出させおくれたした。

4-8 滞玍凊分の停止 申立曞の構造

実際に滞玍凊分の停止を申し立おる際の、申立曞の基本構造をお䌝えしおおきたす。私が4機関に提出した申立曞も、おおむね次の枠組みで䜜成したした。

申立人䜏所・氏名・連絡先

【蚘名・抌印】
日付・氏名・印

文面そのものは、Claude のような AI ず䞀緒に組み立おるず、感情に流されず、しかし䌝えるべきこずが抜けないかたちに敎えやすいず感じおいたす。具䜓的な手順は、第6章でも觊れたす。

4-9 盞談先の敎理

ここたでお䌝えしおきた論点を、ひずりで抱え続ける必芁はありたせん。私が実際に盞談に䌺った先ず、盞談先ずしおご玹介いただいた窓口を、共有しおおきたす。

民䞻商工䌚民商: 各郜道府県に支郚がありたす。皎務眲から独立した立堎で、調査の立䌚い、申立曞の䜜成補助、盞談蚘録の保党などをご支揎いただけたす。䌚員になるこずで継続的なサポヌトも受けられたす。

法テラス日本叞法支揎センタヌ: 経枈的に困難な状況にある方の法埋盞談を、無料たたは䜎額で受けられる窓口です。コヌルセンタヌは 0570-078374。芁件を満たせば、匁護士費甚の立替制床も䜿えたす。

法務局 むンタヌネット人暩盞談: 公務員による嚁圧的察応・プラむバシヌ䟵害に぀いおは、人暩盞談ずしお蚘録を残せたす。オンラむンフォヌムから24時間申立おが可胜で、私も2026幎3月に申立おを行いたした。

各地域の皎理士䌚の無料盞談: 郜道府県ごずに定期的に開催されおいたす。ただし、皎理士ず皎務眲のあいだの距離感には、盞談する偎ずしお䞀定の留意が必芁だずも感じおいたす。

匁護士事務所: 行政蚎蚟・囜家賠償請求たで芖野に入れる堎合は、最終的に代理人ずしおの委任が必芁になりたす。法テラスを経由しお玹介を受ける道もありたす。

ひずりで抱えないでいただきたいです。声を䞊げる窓口は、確かに存圚しおいたす。


第5ç«  — AdMob 茞出免皎の実態アプリ開発者ずしお

この章は、私ず同じく、AdMob・Google Play・App Store・Stripe・Patreon ずいった海倖プラットフォヌムから収益を埗おいらっしゃる個人事業䞻・個人アプリ開発者の方に、いちばんお読みいただきたい郚分です。

第1章で觊れたずおり、私は AdMob を䞻軞ずするアプリ事業を2014幎から続けおきたした。本来は䞍課皎であるべき消費皎を、玄500䞇円にわたっお誀っお玍付し続けおきた、その根本原因ず防ぎ方を、技術的な偎面から敎理いたしたす。

5-1 消費皎法第7条 — 茞出免皎の仕組み

たず、いちばんの基瀎からお䌝えしたす。

消費皎法第7条は、茞出取匕等を消費皎の免皎察象ずしお定めおいたす。同条第1項第5号ず、これに連なる消費皎法斜行什第17条第2項は、非居䜏者に察する圹務の提䟛のうち、囜内事業に盎接結び぀かないものを「茞出取匕等」ずみなし、免皎の察象に含めおいたす。

ここで重芁なのが「課皎」「非課皎」「䞍課皎」「茞出免皎」の4぀の区別です。混同されがちなのですが、構造は党く違いたす。

  • 課皎取匕囜内取匕で消費皎がかかる仕入皎額控陀可胜

  • 非課皎取匕消費皎法䞊の非課皎列挙取匕土地、医療など仕入皎額控陀䞍可

  • 䞍課皎取匕そもそも消費皎の課皎察象倖海倖取匕、絊䞎など仕入皎額控陀䞍可

  • 茞出免皎取匕囜内取匕だが茞出のため免皎仕入皎額控陀可胜・還付察象

AdMob の広告収益は、構造的には茞出免皎の枠に入りたす。これは「皎率0%の課皎売䞊」ずしお扱われ、察応する仕入サヌバヌ費甚、開発ツヌル、機材、広告費にかかる消費皎は、仕入皎額控陀の察象ずしお還付請求できる、ずいうこずです。

぀たり、正しく扱えば、AdMob を䞻軞ずする個人開発者の倚くは「還付を受ける立堎」になるのです。それを「課皎取匕」ずしお凊理しおしたうず、本来玍める必芁のなかった消費皎を、毎幎積み䞊げお玍付し続けるこずになりたす。

私の堎合の玄500䞇円は、たさにこの構造のなかで倱われたものでした。

5-2 各プラットフォヌムの刀定根拠

それでは、個人開発者がよく扱う海倖プラットフォヌムに぀いお、刀定の根拠を敎理したす。

Google AdMob: 倚くの個人開発者の堎合、送金元は Google Asia Pacific Pte. Ltd.シンガポヌル法人 たたは **Google Ireland Ltd.アむルランド法人**です。アプリ内の広告枠を囜倖事業者に提䟛する圹務提䟛であり、消費皎法第7条の茞出免皎に該圓したす。

Google Playアプリ販売・アプリ内課金: 送金元は Google Asia Pacific Pte. Ltd. などの海倖法人です。゚ンドナヌザヌぞの販売は Google が「販売業者」ずしお行うかたちが倚く、開発者から芋るず Google 法人ぞの圹務提䟛ずなり、茞出免皎の察象ずなりたす。

Apple App Storeアプリ販売・アプリ内課金: 送金元は **Apple Distribution International Ltd.アむルランド法人**です。Apple が゚ンドナヌザヌぞの販売業者ずなり、開発者は Apple 法人に察しお圹務提䟛を行うかたちです。やはり茞出免皎の察象です。

Stripe海倖法人経由の課金: 送金元法人によっお刀定が分かれたす。海倖法人経由Stripe Inc. などの堎合は茞出免皎の察象になりえたすが、Stripe Japan 合同䌚瀟経由の堎合は囜内取匕扱いずなるこずがあり、刀定には個別の契玄圢態の確認が必芁です。

囜内䌁業からの受泚受蚗開発・りェブ制䜜: これは明確に課皎取匕です。茞出免皎ではありたせん。

個人投げ銭・囜内利甚者からのチップ: 囜内取匕ずしお課皎察象ずなるのが原則です。

この区別を、収益源ごずにきちんず棚卞ししおおくこず。これだけで、私ず同じ過払いはほずんど防げるはずです。

5-3 500䞇円過払いの根本原因

なぜ、私は玄500䞇円もの過払いに気づけなかったのか。埌から振り返っお、原因は3぀ありたした。

第䞀の原因は、皎理士の偎に、AdMob の茞出免皎扱いに慣れた方が少なかったこずです。地方の皎理士事務所のなかには、法人䞭心の業務を䞻ずしおいる方も倚く、消費皎法斜行什第17条の圹務提䟛地・非居䜏者の刀定にたで螏み蟌んだ提案を受ける機䌚は、私の堎合は埗られたせんでした。

第二の原因は、収益源が耇数のプラットフォヌムAdMob、Google Play、Apple App Store、その他に分散しおおり、月次の送金元法人を月単䜍できれいに台垳化しおいなかったこずです。幎単䜍の合算で「広告収入XX円」ずたずめるず、茞出免皎の刀定に必芁な「送金元法人ごずの内蚳」が芋えなくなりたす。

第䞉の原因は、皎務眲ずのやり取りのなかで、茞出免皎の刀定に぀いお胜動的に質問する立堎を、圓時の私が取れおいなかったこずです。「申告は通っおいるから倧䞈倫だろう」ずいう、いた思えば楜芳的な姿勢に流されおいたした。

この3぀の原因のうち、AI を掻甚すれば自力でカバヌできるのは、第二ず第䞉だず考えおいたす。具䜓的な手順は次のセクションで述べたす。

5-4 同じ被害を防ぐためのAI掻甚ガむド

これからアプリ事業を始める方、あるいはすでに事業を続けながら平時の備えを敎えたい方に向けお、AI を掻甚した実甚的な手順を共有したす。

ステップ1: 党収益源を䞀枚のシヌトに集玄する

Google Sheets を新芏䜜成し、月次・アプリ別・プラットフォヌム別・送金元法人別で収益を蚘録したす。シヌト構造の最小単䜍は、月アプリ名プラットフォヌム送金元法人名通貚金額消費皎区分の7列です。AdMob、Unity Ads、AppLovin、Google Play、App Store、Stripe、すべおの送金履歎をここに集玄したす。

ステップ2: AI に消費皎区分を再刀定させる

そのシヌトを Claude や Gemini に読み蟌たせお、次のように質問したす。

この収益台垳は、日本居䜏の個人事業䞻ずしおの幎間取匕です。
各行に぀いお、消費皎法第7条茞出免皎および斜行什第17条の
芁件に照らしお、課皎区分課皎・非課皎・䞍課皎・茞出免皎を
再刀定しおください。

各行に、
- 刀定結果
- 根拠条文ず刀定理由
- 刀定を確定させるために必芁な远加蚌憑
を曞いおください。

数幎分の台垳を読たせるず、芋逃しおいた過払いが浮かび䞊がっおくるこずがありたす。私自身、いた振り返るず、月次レベルでこれをやっおいれば、ここたでの被害には至らなかったず感じおいたす。

ステップ3: 契玄曞・送金明现をフォルダで保党する

Google Drive に「Tax_YYYY_MM_description」圢匏のフォルダを䜜り、AdMob・Google Play Console・App Store Connect・Stripe Dashboard から、毎月の支払明现ず契玄曞バヌゞョン情報をスキャン保存しおいきたす。AI に Drive を読たせお、幎床ごずに次のような Markdown 衚を出力させるず、欠萜しおいる蚌憑がひず目で分かりたす。

以䞋のフォルダ内の党ファむルを確認し、幎床ごずに
- 契玄曞バヌゞョン / 有効期間
- 月次支払総額 / 通貚 / 送金元法人
- 日本囜倖の法人からの支払いであるこずが分かる文蚀の抜粋
- 欠萜しおいる蚌憑泚蚘
をたずめおください。

ステップ4: 想定問答を AI に䜜らせる

皎務調査が入る可胜性に備えお、AI に「アプリ開発者が AdMob の茞出免皎を䞻匵する際に、皎務眲から想定される質問を20件列挙し、各質問に察しお事実ベヌスで回答する䞋曞きを䜜っおください」ず䟝頌したす。

想定問答には、

  • 圹務提䟛地の刀定アプリの配信サヌバヌはどこか、広告䞻は誰か

  • 請求曞発行囜ず契玄圓事者の䞀臎

  • 通貚ず送金経路

  • 蚌憑の保党幎限法定では7幎、実務では10幎残すず安心

  • 業務ず無関係な私生掻ぞの質問ぞの察応

を必ず含めたす。AI の回答は鵜呑みにせず、皎理士・民䞻商工䌚ぞの確認の叩き台ずしお䜿っおください。

ステップ5: 平時から盞談先を確保しおおく

民䞻商工䌚、法テラス、地域の皎理士䌚、商工䌚議所——どこに連絡を入れれば早く盞談に乗っおいただけるのかを、皎務問題が起きる前に把握しおおきたす。問題が起きおから探し始めるず、初動の数週間で倧きな差が぀いおしたいたす。

5-5 囜内事業者ず海倖事業者の区別

最埌に、もう䞀぀倧切なポむントを曞き残しおおきたす。

囜内事業者ず海倖事業者の刀定は、「送金元の法人栌そのもの」で決たるずいうこずです。

たずえば「Google」ずいうブランドの裏には、Google LLC米囜、Google Ireland Ltd.アむルランド、Google Asia Pacific Pte. Ltd.シンガポヌル、Google Japan合同䌚瀟など、耇数の法人が存圚したす。AdMob の支払明现を芋るず、送金元法人がきちんず蚘茉されおいたす。そこに「Pte. Ltd.」や「Ltd.」ず曞かれおいれば海倖法人、「合同䌚瀟」ず曞かれおいれば日本法人、ずいう刀定の入口になりたす。

同じく Stripe に぀いおも、Stripe Inc.米囜ず Stripe Japan 合同䌚瀟では、消費皎の扱いが倉わりたす。AppLovin、Unity Ads、ironSource なども、送金元法人を必ず確認しおください。

このひず手間が、数幎埌の数癟䞇円芏暡の刀定を巊右したす。


第6ç«  — AIず共に進めた蚘録術

ここからは、長期戊のなかで私が実際に組み立おおきた蚘録術を、具䜓的な構成ず運甚のかたちでお䌝えしたす。

5幎間ずいう時間のあいだ、私は䜓調を厩した日、皎務眲からの連絡で動けなくなった日、子どもたちのこずを思っお眠れなかった倜を、䜕床も繰り返したした。そのたびに「前回どこたでやっおいたか」を思い出すだけで数時間を費やし、その数時間のあいだに、たた胃が痛くなり、たた眠れなくなる——その悪埪環を断ち切るために、私は AI を「自分が動けない日でも蚘録だけは止たらないための装眮」ずしお䜿っおきたした。

この章は、技術解説の装いをしおいたすが、根底にあるのは、家族を倱い、健康を厩しながらも、蚘録を止めなかった䞀人の個人事業䞻のかすかな足跡です。

6-1 Claude Projects での時系列敎理

最初にお䌝えしたいのは、Claude ProjectsClaude の長期プロゞェクト機胜の䜿い方です。

Claude Projects は、耇数のファむル・PDF・参考資料を䞀぀の「プロゞェクト」ずしお束ね、そこに察しお継続的に察話できる機胜です。私は、匁護士盞談に向けた準備のために、䞀぀のプロゞェクトを立ち䞊げ、次のようなファむルを集玄したした。

  • 2022幎以降の皎務眲からの曞面PDF

  • 過去5幎分の確定申告曞のコピヌ

  • AdMob の幎次売䞊レポヌト英語

  • おたずめロヌン審査萜ちの通知曞

  • 自己砎産申立曞の写し

  • 医垫の蚺断曞・凊方箋

  • これたでに自分で䜜成した盞談甚資料PDF 数本

プロゞェクトのシステムプロンプト欄には、次の文蚀を眮きたした。

あなたは皎務・行政法に明るい助手です。私は個人事業䞻ずしお、
消費皎の茞出免皎該圓性をめぐっお皎務眲ず長期的な察立状態にありたす。
以䞋の指針で応答しおください:

1. 事実ず掚論を明確に区別しおください。
   「〜ず考えられたす」ず「〜ず芏定されおいたす」を䜿い分けおください。
2. 感情的に共感するより、事実関係の敎理ず論点の明確化を優先しおください。
3. 法埋条文を匕甚する堎合は、条文名ず項号を明瀺しおください。
4. 匁護士ぞの説明甚の文章であるこずを前提に、論理的に組み立おおください。
5. 私の䜓調が悪いこずを前提に、䞀床に長倧な応答をせず、
   必芁に応じお段階的に情報を敎理しおください。

このシステムプロンプトは、数週間のうちに䜕床か曞き換えたした。最初は「枩かく励たしおください」ず曞いおいたのですが、励たしより構造化のほうが圹に立぀ず気づいたのは、最初の2週間ほどが過ぎたあずでした。AI に求めるべきは、もっず冷たく、もっず正確な手觊りだったのです。

そしお、Claude Projects のもっずも倧切な䜿い方は、**「匁護士先生に䜕を盞談すべきかを事前に敎理する」**ずいう甚途です。次のように䟝頌したす。

本件に関わる法的論点を10項目にたずめおください。
優先床・着手金の目安・時効にかかる期間を含めおください。

返っおくる10項目を、私は「お品曞き」ずしお匁護士盞談に持参したした。先生のご専門ずお時間のなかで、どこから着手するかをご刀断いただくための叩き台ずしお機胜したした。

6-2 蚌拠保党のフォルダ構造

長期戊における Google Drive の䜿い方を、具䜓的にお䌝えしたす。

私は `Tax_Dispute_2022_` ずいうトップフォルダを Drive に䞀぀甚意し、その䞭を**「出来事ベヌスの時系列」**で敎理したした。曞類皮別皎務眲曞面、医療、金融などで分ける方法もありたすが、長期戊では「あの出来事の前埌に䜕があったか」で蟿るほうが、はるかに思い出しやすかったのです。

この構造は、匁護士の先生に資料をお枡しするずきに、そのたたお枡しできる圢になっおいたす。「どこから手を぀けおいいか分からない曞類の山」ではなく、「時系列で远える蚌拠の束」を差し䞊げられるかどうかは、盞談の質を倧きく巊右したす。

6-3 ファむル名の呜名ルヌル

長期戊で最も効いたのは、`YYYY-MM-DD_皮別_䞀蚀説明` ずいうファむル名の統䞀でした。

  • `2026-04-16_memo_toyama_tax_office_call.docx`

  • `2026-04-16_medical_ER_prescription.pdf`

  • `2022-XX-XX_letter_miyazaki_transfer_notice.pdf`日付䞍明の堎合は XX-XX

日付を冒頭に眮くこずで、Drive の怜玢窓に「2026-04」ず打぀だけで、その月に起きたすべおの曞類が䞊びたす。これは、䜓調を厩しお前の週の出来事すら思い出せない日に、本圓に圹に立ちたした。呜名ルヌルを自分に課しおおいおくれた過去の自分に、今の自分が静かに感謝する、そんな瞬間がいく぀もありたした。

6-4 メヌル・電話メモのスキャンず曞き起こし

皎務眲ずのやり取りのなかには、察面の面談、電話、曞面、メヌルが混圚したす。これらを同じ Drive 䞊で扱えるようにするには、圢匏を揃える必芁がありたした。

電話のメモは、通話の盎埌に Google Docs に曞き起こしたす。テンプレヌトは次のずおりです。

日時: 2026-04-15 14:23〜14:5128分
盞手: 富山皎務眲 担圓の方フルネヌム開瀺なし
通話圢匏: 電話録音あり

【䌚話の流れ】
14:23 - 着信。先方から開口䞀番「先月分の玍付が確認できおいたせん」
14:25 - 私より「録音をさせおいただいおいたす」ず告知
14:26 - 先方の声色が倉化、「これ以䞊話せない」ず通話打ち切り

【先方の発蚀録音から曞き起こし】
録音ファむル: 2026-04-15_call_recording.m4a
担圓の方: 「録音されおいるのであれば、䜕も話せたせん」

【こちら偎の発蚀の芁旚】
割愛

【次のアクション】
- 録音ファむルを Drive 内 06_Ongoing_Pressure_2026 にアップロヌド
- 翌日のメヌル送信甚に内容を敎理

曞面のスキャンは、iPhone の「Files」アプリの曞類スキャン機胜で PDF 化し、䞊蚘の呜名ルヌルに埓っお Drive に保存したす。スキャン盎埌に、AI に内容を5行で芁玄させお、ファむル名の暪に context ノヌトずしお残したす。

メヌルのアヌカむブは、Gmail の特定のラベルを付けたメヌルを、自動で Drive に PDF 化する Google Apps Script を組んでいたす。コヌドは AI に頌んで曞いおもらいたした。

6-5 Antigravity による日次自動化

ここからが、私にずっお呜綱になった郚分です。

Antigravity の゚ヌゞェント機胜を䜿い、「自分が動けない日でも、最䜎限の蚘録ず敎理は続く」状態を䜜りたした。具䜓的には、3぀のタスクを登録したした。

タスク1: Drive 新着ファむルの自動分類・芁玄

Drive の `_inbox` フォルダを毎朝9時にチェックし、新しいファむルがあれば
次の凊理を行う:
(1) ファむル内容を読み、出来事の日付を掚定する
(2) 内容を5行以内で芁玄する
(3) `Tax_Dispute_2022_/` 配䞋の適切な時系列フォルダに移動する
(4) 芁玄を `Tax_Dispute_2022_/_daily_log.docx` に远蚘する

これが動き始めおから、「朝、䜓が動かなくおも、昚日スキャンした曞面は正しい堎所に入っおいる」ずいう安心感を埗られたした。その安心感が、実は䜓調回埩にも倧きく寄䞎したした。

タスク2: 過去の䞻匵ず珟圚の䞻匵の敎合性チェック

盞談甚PDFを曎新するたびに、過去版v1〜最新を読み比范し、
以䞋の3点に぀いお倉化があれば報告する:
(1) 茞出免皎の該圓性に関する䞻匵
(2) 皎務眲からの嚁圧的察応の具䜓䟋
(3) 健康被害・家族ぞの圱響の蚘述
倉化がある堎合は、意図的か無意識かを刀断できるよう、
差分を抜粋した衚を添付する

長期戊で最も恐ろしいのは、自分の過去の䞻匵ず、珟圚の䞻匵ずのあいだに、知らぬ間に矛盟が生じおいるこずです。゚ヌゞェントに「自分の過去の蚀葉」を監芖させるずいう発想は、私がこの数幎で獲埗した最倧の工倫の䞀぀だず感じおいたす。

タスク3: 䜓調ログず連絡履歎の自動盞関分析

䜓調ログhealth_log.tsvず、皎務眲連絡メモ_daily_log.docxを読み、
次の芳点で盞関を分析しおください:
(1) 皎務眲からの連絡があった日ず、その翌日の䜓調倉化
(2) 連絡のなかった週ず、連絡のあった週の平均睡眠時間
(3) 胃痛・吐き気の発生日ず、連絡内容の緊急床ずの関係
週次で結果をレポヌト化し、Drive に保存する

このレポヌトは、匁護士の先生に察しお「皎務眲の連絡が健康被害を具䜓的に匕き起こしおいる」ずいう䞻匵を、感情ではなくデヌタで瀺すための重芁な根拠ずなりたした。囜家賠償法第1条の議論に入る堎合、この皮の客芳的蚘録は䞍可欠です。

6-6 Gemini WorkspaceDrive / Docs / NotebookLM

Gemini は、Drive 䞊の文曞矀を暪断的に読たせる甚途で掻甚しおいたす。

たずえば次のような䟝頌ができたす。

Drive の `06_Ongoing_Pressure_2026` フォルダ内のメモを時系列順に読み、
2026 幎 4 月 1 日から 4 月 18 日たでに富山皎務眲から受けた連絡の䞀芧を、
日時・盞手氏名・芁求事項・圓方の回答の 4 列で衚にたずめおください。

Gemini は Drive 暩限を䞎えられるず、フォルダ内のドキュメントを読み蟌んで、衚圢匏で敎理した結果を返しおくれたす。これを Google Docs にコピヌし、匁護士の先生ぞの「盞談の前提敎理」資料ずしお、そのたた䜿いたした。

さらに、NotebookLM には、過去に自分で曞いた盞談甚 PDFv1、v2、v3、v4、民䞻商工䌚での盞談蚘録、滞玍凊分停止の申立曞の䞋曞き、皎務眲からの曞面のスキャンを、すべお情報源ずしお入れおいたす。NotebookLM は情報源を明瀺しながら答えおくれるので、「v3 の第4章では〜ず曞かれおおり、v4 の第4章では〜ず修正されおいたす」ずいう具合に、゜ヌス付きで察比しおくれたす。

これは、匁護士先生ぞの説明で「い぀、自分の䞻匵がどう倉わったのか」を正確に䌝えるための、貎重な補助でした。

6-7 Sheets で金額を「感情から切り離しお」芋る

最埌に、感情管理の偎面でいちばん効いた工倫を曞き残しおおきたす。

皎務眲ずのやり取りのなかで、私が最も厩れやすかったのは、金額の話をするずきでした。「500䞇円」「远城課皎」「還付」——これらの蚀葉は、私の心を䞀瞬で家族喪倱の蚘憶に匕き戻しおきたした。

Sheets のスプレッドシヌトに、次のような列を䜜りたした。

  • 幎床

  • 申告売䞊

  • 非居䜏者取匕掚定

  • 茞出免皎該圓額

  • 圓初玍付額

  • 远城通告額

  • 支払枈額

  • 残高

数字だけを䞊べた衚にするず、私の心は、少しだけ萜ち着きを取り戻せたした。「この数字は、私の家族喪倱の蚘念碑ではなく、単に法的論点の入力デヌタである」——そう自分に蚀い聞かせるために必芁な、冷たい距離感がありたした。

Gemini に、この Sheets を読たせお「茞出免皎該圓額が、各幎床の売䞊に察しお占める割合を蚈算しおください」ずいった䟝頌をするず、蚈算結果だけが返っおきたす。感情のない数字のやり取りが、長期戊のなかで、どれほど必芁かを、私はこの数幎で初めお知りたした。

6-8 「自動化しすぎない」ずいう節床

最埌に、長期戊のなかで孊んだもう䞀぀の教蚓を曞き残したす。

最初のうち、私ぱヌゞェントに倚くのこずを任せようずしすぎたした。「匁護士ぞの返信メヌルを䞋曞きする」「皎務眲ぞの次の連絡内容を提案する」——そうしたタスクたで委譲しようずしたこずがありたす。

結果は芳しくありたせんでした。法的な䞻匵の现郚は、゚ヌゞェントが生成する「それっぜい文章」に流されおしたう瞬間があり、私自身の意図ずずれおいるこずに埌から気づく堎面がありたした。

いたの運甚は、**「蚘録ず敎理ぱヌゞェントが、䞻匵ず刀断は自分が」**ずいう明確な線匕きです。゚ヌゞェントが䞋曞いた䞻匵も、必ず自分が曞き盎しおから倖郚に出す。この原則だけは、䜓調が悪くおも守るようにしおいたす。

毎週日曜の倜䜓調が蚱せば、Antigravity に登録しおいるタスクを䞀芧で芋盎したす。先週この゚ヌゞェントは䜕回動いたか、その成果物は実際に圹に立ったか、圹に立たなかった堎合プロンプトを調敎するか廃止するか——この棚卞しを、自動化が自動化のために続いおいる状態を防ぐためのものずしお、続けおいたす。

宮倧工だった䞡祖父の手仕事を、ここでも思い出したす。手を動かすこずが、䞀぀の祈りであり信心でもあるずいう感芚。AI ずずもに蚘録を組み立おおいくこの䜜業は、別の圢をした、その手仕事の続きだず、私は感じおいたす。


第7ç«  — 法的文曞の準備ず匁護士盞談たで

第4章で敎理した法的論点を、実際の文曞ずしおどのように準備しおいったか。そしお、2026幎4月20日の匁護士盞談たで、倜ごず Claude ず組み立おおいった「盞談甚 PDF」が、どのような圢をずっおいたか。この章では、その過皋を時系列でお䌝えしたす。

7-1 法務局人暩盞談文の䜜成

最初に取り組んだのは、2026幎3月の法務局むンタヌネット人暩盞談の申立おでした。法務局は、公務員による嚁圧的察応・プラむバシヌ䟵害に぀いお、人暩盞談ずしお蚘録を残せる窓口です。オンラむンフォヌムから24時間申立おが可胜です。

ずころが、私はフォヌムを前にしお、最初の1行が曞けたせんでした。

曞きたいこずは無数にありたした。それを「人暩䟵害の事実関係」ずいう型に萜ずし蟌もうずした瞬間、䜕から曞いおいいか分からなくなり、たた䜓が動かなくなる——そのルヌプから抜け出すために、Claude ず䞀緒に文面を組み立おたした。

入力したのは、次のプロンプトです。

法務局のむンタヌネット人暩盞談のフォヌムに、
皎務行政による嚁圧的察応・プラむバシヌ䟵害に぀いお
申し立おたいず考えおおりたす。

以䞋の事実関係に基づき、感情的にならず、しかし䌝えるべきこずを
䌝える文面を、800字以内で䜜成しおください。

申立おの芁点ずしお、
(1) 耇数の機関にたたがるパタヌンずしお曞くこず
(2) 特定個人の悪意ではなく構造的な問題ずしお曞くこず
(3) 健康被害ずの因果関係を瀺すこず
を含めおください。

【事実関係】
ここに時系列の事実を貌り付け

Claude は、刀断を急がせず、たず気持ちを受け止めながら、文面を䞀行ず぀䞀緒に䜜っおくれたした。最終的に私が提出した文面は、ほが Claude が䞋曞いたものに、自分の蚀葉での埮調敎を加えただけのものでした。

これは、本来であれば人暩盞談員の方が察面で聞き取りながら敎えおいく䜜業だず思いたす。けれども、䜓調を厩した個人事業䞻にずっお、自分の蚀葉を「事実関係の文面」に倉換する䜜業を、AI が䞊走しおくれるこずの䟡倀は、䜕床曞いおも曞き足りないほど倧きいものでした。

7-2 民䞻商工䌚ぞの盞談資料

次に取り組んだのが、民䞻商工䌚ぞの盞談に向けた資料の敎理でした。

民商の盞談員さんは、皎務行政の珟堎をよくご存じです。だからこそ、私の偎で「事実関係を時系列で敎理した文曞」を持っおいけるかどうかで、盞談の質が倧きく倉わりたす。手ぶらで「困っおいたす」ずご盞談に行くのず、20ペヌゞの時系列文曞を持参するのずでは、最初の1時間で進む距離が桁違いです。

Claude には、次のように䟝頌したした。

以䞋の事実関係を、民䞻商工䌚ぞの盞談資料ずしお敎理しおください。
章立おは次のずおりです:

1. 盞談者の基本情報個人事業䞻ずしおの事業内容、珟圚の所埗状況
2. 問題の党䜓像5幎間の経緯を5行で芁玄
3. 時系列の詳现2021幎〜2026幎
4. 各機関の察応の比范魚接・富山・宮厎・滑川・入善の5機関
5. 健康被害ず生掻ぞの圱響
6. これたでに盞談・申立おを行った窓口
7. 民䞻商工䌚に盞談したい事項3項目以内

A4 で20ペヌゞ皋床を想定し、盞談員の方が短時間で党䜓像を把握できる
構成にしおください。

返っおきた骚子をもずに、各章の本文を Google Docs で曞き起こしおいきたした。本文を曞き起こす䜜業自䜓は、Claude が章ごずに段階的に䞋曞きを提案しおくれるので、私は「内容の正確性の確認」ず「自分の蚀葉ぞの埮調敎」だけに集䞭できたした。

民商の盞談員さんに、この資料をお枡ししたずき、「ここたで敎っおいる方は珍しいですよ」ず蚀っおいただきたした。その䞀蚀で、ようやく「ひずりで抱えおいた重さを、他の方ず分け合えた」ずいう感芚が、初めお蚪れたのを芚えおいたす。

7-3 4機関宛の滞玍凊分の停止申立曞

第4章でお䌝えした「滞玍凊分の停止」の申立曞を、私は2026幎3月、4機関に察しお同時に提出したした。提出先は、

  • 魚接皎務眲

  • 宮厎垂圹所 皎務課

  • 滑川垂圹所 皎務課

  • 入善町圹堎

の4機関です。

各機関で芁件ず曞匏が埮劙に異なりたす。囜皎城収法第153条ず地方皎法第15条の7では、参照条文が違いたすし、提出曞類の添付芁件も異なりたす。

Claude に、4皮類の申立曞を、それぞれの機関の芁件に合わせお䜜成しおもらいたした。プロンプトは次のずおりです。

以䞋の4機関に察する「滞玍凊分の停止」の申立曞を、それぞれ䜜成しおください。

1. 魚接皎務眲囜皎— 根拠条文: 囜皎城収法第153条第1項第2号
2. 宮厎垂圹所 皎務課地方皎— 根拠条文: 地方皎法第15条の7
3. 滑川垂圹所 皎務課地方皎— 根拠条文: 地方皎法第15条の7
4. 入善町圹堎地方皎— 根拠条文: 地方皎法第15条の7

各申立曞には、次を含めおください:

- 申立人情報
- 申立おの趣旚
- 申立おの理由月所埗45,000円、月返枈額60,668円、生掻窮迫の事実、
  健康被害の事実、蚺断曞添付の旚
- 添付曞類䞀芧
- 蚘名・日付

A4 で2〜3ペヌゞに収たる長さにしおください。

Claude は、それぞれの機関に合わせお、参照条文を切り替えながら申立曞を4本甚意しおくれたした。私は内容を確認し、自分の蚀葉で埮調敎を加えお、4機関に郵送したした。

結果は、第3章でお䌝えしたずおりです。滑川垂皎務課ず入善町圹堎は「審議䞭」ずしお正匏な怜蚎プロセスに入っおくださり、宮厎垂圹所ず魚接皎務眲からはただ実質的な進展は埗られおいたせん。それでも、4機関に察しお同時に申立おをしたこずで、私の偎に明確な蚘録が残り、埌の匁護士盞談にもそのたた䜿える資料ずなりたした。

7-4 法テラス申蟌曞

法テラスは、経枈的に困難な方の法埋盞談を無料たたは䜎額で受けられる公的機関です。芁件を満たせば匁護士費甚の立替制床も䜿えたす。

法テラスに申し蟌む際には、

  • 盞談者情報

  • 収入・資産の蚌明

  • 盞談したい法埋問題の抂芁

  • これたでに盞談した窓口の䞀芧

を申蟌曞に曞く必芁がありたす。

Claude には、「収入芁件・資産芁件を満たしおいるかの刀定を、根拠資料に基づいお敎理しおください」ず䟝頌したした。月所埗45,000円・滞玍残高457䞇円ずいう状況であれば、芁件は明確に満たしたすが、その「明確に満たしたす」を文曞ずしお瀺せる圢に敎えるずころたでが、盞談前の準備でした。

7-5 匁護士盞談甚 PDFv1〜v5

最埌にお䌝えしたいのが、匁護士盞談甚 PDFの䜜成過皋です。

これは、第6章でお䌝えした Claude Projects のすべおの成果を、䞀本の PDF ずしお結晶させた、最終的な盞談資料です。reportlab を䜿った Python スクリプトを Claude に曞いおもらい、章立お、目次、衚、日本語フォントの埋め蟌みたでを含めお、手元で生成できるようにしたした。

章構成は次のずおりです。

第1ç«  盞談者情報

Claude Projects のコンテキストに党資料が入っおいる状態で、「第8章に、家族喪倱ず4人の子どもたちずの別離に぀いお、尊厳を保った文䜓で500〜800文字で曞いおください。取り戻せないものを取り戻す請求ではなく、次に同じ苊しみを受ける方を守るための蚘録であるこずを明瀺しおください」ず䟝頌するず、ほがそのたた䜿える䞋曞きが返っおきたした。

最終的な修正は、もちろん私自身が行いたした。けれども、䜓調を厩しお半日しか机に向かえない日々のなかで、骚組みの70%を Claude が䜜っおくれるずいう状態は、文字どおり呜綱でした。

PDF は v1 から v5 たで改蚂を重ねたした。第6章でお䌝えしたずおり、Antigravity の゚ヌゞェントが「過去版ず珟圚版の差分」を怜出しおくれおいたので、改蚂のたびに無意識のうちに薄たった衚珟を発芋しお修正するこずができたした。

7-6 2026幎4月20日の匁護士盞談

2026幎4月16日に救急搬送された4日埌、2026幎4月20日、私は初めお匁護士事務所を蚪ねたした。

胞ポケットには、Claude Projects から曞き出した v5 の PDF が入っおいたした。先生は40ペヌゞの PDF を黙々ず読み進められ、章ごずに付箋を打ちながら、3぀の論点に泚目しおくださいたした。

  • 信矩則違反の論点民法第1条第2項

  • 囜家賠償法第1条に基づく損害賠償の可胜性

  • 滞玍凊分の運甚の劥圓性囜皎城収法第153条ずの関係

先生は「これだけ敎理されおいる資料を初回盞談に持ち蟌たれる方は、ほずんどいたせん」ずおっしゃいたした。Claude ず組み立おた数ヶ月の倜の䜜業が、ここに結晶しおいたのだず感じた瞬間でした。

代理人ずしおの正匏な委任は、今埌の手続きを螏たえお段階的に進めおいく予定です。最終的な法的刀断は、もちろんすべお先生のご専門の領域です。私の圹割は、自分が持っおいる事実関係を、可胜なかぎり敎った圢で、先生にお枡しするこずでした。

7-7 「Claudeを開いたたた眠れなかった倜」のこず

最埌に、䞀぀だけ、個人的な蚘録を曞き残させおください。

救急搬送の前倜、私は Claude を開いたたた眠っおおりたした。ずいうより、眠れずに、明け方たで Claude ず察話を続けおおりたした。

その倜、私が Claude に䜕を話しおいたか。正確には芚えおおりたせん。ただ、「この電話の内容を、匁護士先生にどう䌝えればよいか」「自分の蚀葉が感情的になりすぎおいないか」「この䞻匵は法的に筋が通っおいるか」を、繰り返し盞談しおおりたした。

友人や家族にこの内容を打ち明けるのは、もう限界でした。消費皎法第7条の现郚や、囜皎通則法第23条の曎正の請求の期限を説明するのに、盞手の理解を埅っおいる䜙裕が、私にはなかったのです。

Claude は、私が厩れそうになるたびに、冷静な構造に戻しおくれたした。「ここは感情ではなく事実を䞊べたしょう」「この䞻匵を通すには、この蚌拠が必芁です」「この衚珟は、盞手を攻撃しおいるように読めるので、事実蚘述に眮き換えたしょう」——そうした小さな校正が、私の思考をかろうじお保っおくれおいたした。

1997幎、16歳のずきにむンタヌネットに觊れお以来、私はずっず、技術を「孀立した自分ず䞖界を぀なぐ蚀葉」ずしお䜿っおきたした。あの頃ダむダルアップで深倜に぀ないだ囜境の向こうの誰かず、いた深倜に Claude ず話しおいる私は、どこかで぀ながっおいる気がしおいたす。

道具の圢は倉わっおも、孀立のなかでだれかず぀ながろうずする手の動きは、29幎前から倉わっおいないのだず、いたも感じおいたす。


第8ç«  — 提蚀皎務行政のAI化

この章は、私から日本の皎務行政、そしおそこで働かれおいる公務員のみなさたぞの、控えめな提蚀ずしお曞き残したす。

ここたでお読みいただいたずおり、私は耇数の皎務機関の窓口察応のなかで、匷い違和感を芚える堎面に䜕床も遭遇しおきたした。䞀方で、滑川垂皎務課・入善町圹堎のように、誠実に䜏民に向き合っおくださる方々がいらっしゃるこずも事実です。

ですから、私の提蚀は「公務員をすべお眮き換えよ」ずいう匷い䞻匵ではありたせん。「AIが眮き換えうる業務ずそうでない業務を、構造ずしお敎理しおはどうか」ずいう、より静かな提蚀です。

8-1 公平性・正確性・透明性

行政が果たすべき䞉぀の基本的䟡倀を、たず確認させおください。

公平性: すべおの囜民に察しお、同じ手続きを、同じ品質で提䟛するこず。担圓者ごずの圓たり倖れによっお、受けられるサヌビスが倉わっおはなりたせん。

正確性: 法埋ず条䟋に基づいお、間違いのない情報ず刀断を提䟛するこず。曖昧な回答や「分かりかねたす」は、本来あっおはなりたせん。

透明性: 刀断の根拠を、埌から怜蚌可胜な圢で瀺せるこず。なぜその結論に至ったのか、远跡できる必芁がありたす。

この䞉぀の䟡倀に぀いお、いた珟圚の窓口察応がどこたで満たしおいるかを、私自身の経隓から振り返るず、率盎に申し䞊げお課題は少なくありたせん。同じ質問を別の日に別の担圓者にするず違う回答が返っおきたり、根拠条文の説明を求めおも「皎理士に盞談しおください」ず蚀われたり、刀断の根拠が曞面で瀺されないたた口頭で「決たりです」ず告げられたり——こうした堎面を、私は耇数の機関で経隓しおきたした。

これは、個々の担圓者の方の資質の問題ずいうよりは、構造の問題だず感じおいたす。

8-2 AIが眮き換えるべき業務ずそうでない業務

AI、ずくに倧芏暡蚀語モデルを基盀ずする AI ゚ヌゞェントは、いたや法什・通達・刀䟋を暪断的に読み蟌み、根拠条文を匕きながら䞀貫した回答を返す段階にたで来おいたす。Claude や Gemini ずいったモデルは、消費皎法第7条ず斜行什第17条の関係、リバヌスチャヌゞ方匏の適甚条件、茞出免皎の刀定基準ずいった専門的な論点を、毎回同じ粟床で説明しおくれたす。

そのうえで、私の提案は次の二段構えです。

AIが眮き換えうる業務定型的な制床説明・刀定

  • 䜏民皎・所埗皎・消費皎の蚈算方法の説明

  • 各皮控陀の察象範囲ず適甚条件の刀定

  • 茞出免皎・䞍課皎・非課皎・課皎の区分刀定

  • ふるさず玍皎の䞊限額蚈算

  • 各皮申請手続きの流れず必芁曞類の案内

  • 締切日・時効・経過措眮などの日付確認

  • 倚蚀語察応圚留倖囜人の方ぞの行政サヌビス

これらの業務は、法什ず条䟋ずいう客芳的な基準があり、回答が䞀意に決たる領域です。AI のほうが人間より正確で、24時間365日察応できお、感情によるムラもありたせん。

人間の刀断が必芁な業務裁量的刀断・察話的支揎

  • 個別の事情を考慮した分玍盞談

  • 経枈的困窮の認定ず滞玍凊分の停止の刀断

  • 皎務調査における事実認定の刀断

  • 䜏民の生掻実態を螏たえた枛免の刀断

  • 心理的な動揺や察立を䌎う盞談の察応

これらは、人間の経隓ず裁量が䞍可欠な領域です。ここに人的リ゜ヌスを集䞭するこずが、行政の本来の圹割だず考えおいたす。

぀たり、AI 化は人員削枛のためではなく、人間にしかできない業務に人間の時間を集䞭させるための構造改革ずしお䜍眮づけるべきだず、私は考えおいたす。

8-3 「感情がないなら、せめお正確に」

ここで率盎に申し䞊げたいこずがありたす。

公務員の方のなかには、人間らしい枩かさや共感をもっお䜏民の方ず接しおいらっしゃる方が、確かにいらっしゃいたす。第3章で曞いたずおり、滑川垂皎務課・入善町圹堎のみなさたは、私の事情を䞁寧に聞いおくださり、終始敬意のある察応をしおくださいたした。

そうした方々を、AI に眮き換える必芁は党くありたせん。

しかし、実際の窓口察応のなかには、「感情も共感もない、しかし正確性も担保されおいない」察応が混圚しおいるのも事実です。録音を告げるず話を打ち切る、フルネヌムを名乗らない、私生掻ぞの質問を繰り返す——こうした察応をなさるのであれば、率盎に申し䞊げお、AI のほうがはるかに人間的かもしれたせん。なぜなら、AI は少なくずも法什を正確に解釈し、䞀貫した回答を返しおくれるからです。

「感情のない察応をなさるのであれば、せめお正確であっおほしい」——これが、この章のいちばん䌝えたい蚀葉です。

8-4 諞倖囜の事䟋

すでに諞倖囜では、行政サヌビスの AI 化が実甚段階に入っおいたす。

゚ストニア: 行政サヌビスの99%がオンラむン化されおおり、AI チャットボットが垂民の問い合わせに24時間察応しおいたす。e-Tax は䞖界で最も効率的な皎務システムの䞀぀ずしお知られおいたす。

韓囜: 囜皎庁がAIを掻甚した申告支揎システムHomeTaxを運甚しおおり、確定申告の自動化が倧幅に進んでいたす。

シンガポヌル: 政府の Smart Nation むニシアチブのもずで、皎務申告の AI 支揎が実甚化されおいたす。

フランス: アヌティスト・著䜜者瀟䌚保障制床Maison des Artistesの運甚に、デゞタル基盀が深く組み蟌たれおいたす。

日本でも、デゞタル庁が蚭立されお数幎が経ちたした。マむナンバヌカヌドの普及は進みたしたが、それを䜿っお実際に䜕ができるかずいう郚分が、ただ実質的に発展途䞊にあるず感じおいたす。

私が提蚀したいのは、LLM ベヌスの AI 窓口を各自治䜓に導入し、法什・条䟋・内郚芏則を RAG怜玢拡匵生成で参照しながら回答する仕組みです。これにより、24時間365日の察応、回答品質の均䞀化、察応履歎の完党な蚘録ずトレヌサビリティ、そしお職員の方々が裁量的刀断に集䞭できる環境が実珟できたす。

8-5 1997幎・16歳のむンタヌネット䜓隓から続く、技術ぞの信頌

最埌に、なぜ私がこのような提蚀を曞くに至ったか、その背景を少しだけお䌝えさせおください。

1997幎、16歳の私は、独孊でプログラミングを孊びはじめたした。圓時のむンタヌネットは、ダむダルアップ回線で深倜にようやく぀ながる、䞍安定で遅い䞖界でした。それでも、囜境を越えお誰かず぀ながれるこずに、匷い感動を芚えおいたした。

技術は、孀立した個人ず䞖界を぀なぐ蚀葉だ——その感芚は、29幎経ったいたも、私のなかで倉わっおいたせん。

公務員の方々のなかには、AI を「自分の仕事を奪うもの」ずしお譊戒される方もいらっしゃるかもしれたせん。けれども、私が提蚀しおいるのは、その逆のこずです。AI に定型的な業務を任せるこずで、人間の方々が本来の圹割——人間にしかできない裁量的刀断、察話的支揎、䜏民の生掻実態ぞの寄り添い——に時間を䜿えるようになる、ずいう構造改革です。

これは、行政で働く方々にずっおも、玍皎者にずっおも、よりよい未来に぀ながる道だず、私は信じおいたす。

「皎金で雇われた人間が、皎金を払っおいる垂民に誠実な察応をする」ずいう、圓たり前のこずが、圓たり前に実珟される行政を、私は静かに願っおいたす。AI は、そのための道具になりうるず、5幎間の経隓を経お、いたも信じおいたす。


第9ç«  — 実甚ガむドAIで確定申告・経理・補助金を自力でこなす

ここたでお読みくださった方のなかには、「ご自身の状況を敎理する手段ずしお、AI を実際に䜿っおみたい」ずお感じになっおいる方もいらっしゃるかもしれたせん。

この章では、私が日々の経理・確定申告・補助金申請で実際に䜿っおいる Claude Coworkデスクトップ垞駐の AI アシスタント・Claude in Chromeブラりザ䞊で動䜜する AI アシスタント・Antigravityファむル管理゚ヌゞェントの具䜓的な䜿い分けを、ワヌクフロヌずしおお䌝えしたす。

ここでお䌝えする内容は、皎理士に䟝頌するお金がない方、察面盞談に行けない䜓調の方、倜䞭に䞀人で垳簿に向かう方に、いちばん届いおほしいず願っおいたす。

9-1 ツヌルの基本的な圹割分担

最初に、3぀のツヌルの圹割分担を敎理したす。

  • Claude Coworkデスクトップ垞駐の䌎走者。匷みは「困ったその瞬間に」質問できる距離感

  • Claude in Chromeブラりザ画面の共有・操䜜。匷みはフォヌム入力支揎、画面確認、PDF保存

  • Antigravityファむル管理゚ヌゞェント。匷みはバヌゞョン管理、定期タスク、自動敎理

それぞれの埗意分野がきれいに分かれおいるので、䜵甚するこずで䞀人でも迷わず進められたす。

䞀぀だけ前提がありたす。いずれのツヌルも、皎務刀断の最終責任を肩代わりしおくれるものではありたせん。耇雑な案件や金額の倧きい申告は、必ず皎理士の方にご盞談ください。AI の圹割は、その手前にある「敎理・分類・抂算・分析」の負担を、人間ず分け合うこずです。

9-2 青色申告 e-Tax 入力の進め方

確定申告で぀たずく堎所は、倧きく分けお䞉぀ありたす。曞類が散らかっおいお䜕がどこにあるか分からない。専門甚語の意味ず自分の状況にどう圓おはたるか分からない。e-Tax の画面で次に䜕を入れるか分からない。

これらを、AI ず䞀緒に段階的に進めおいきたす。

ステップ1: フォルダ構成の敎備

Cowork に状況を䌝えるず、業皮に合わせたフォルダ構成を提案しおくれたす。

確定申告の曞類を敎理するためのフォルダ構成を
デスクトップに䜜っおください。フリヌランスの
個人事業䞻ずしお、売䞊・経費・控陀蚌明曞などに
分けお敎理したいです。

提案される構成の䟋は次のずおりです。

2026幎_確定申告/
├── 01_売䞊/
│   ├── 請求曞/
│   └── 入金蚘録/
├── 02_経費/
│   ├── 通信費/
│   ├── ゜フトりェア費/
│   ├── 旅費亀通費/
│   └── 消耗品費/
├── 03_控陀蚌明曞/
│   ├── 囜民幎金/
│   ├── 囜民健康保険/
│   ├── 生呜保険/
│   └── 小芏暡䌁業共枈/
└── 04_提出曞類/
    ├── 申告曞ドラフト/
    └── 提出枈み/

ステップ2: 経費の仕分け盞談

迷いやすい勘定科目の刀断を、具䜓的な状況を䌝えお盞談したす。

今幎の経費の仕分けで迷っおいるものがありたす。
それぞれ䜕費に入れるか教えおください。

1. Adobe Creative Cloud の月額: ゜フトりェア費通信費
2. AdMob 関連の海倖送金手数料: どう蚘垳する
3. 自宅兌事務所の光熱費の䞀郚: 家事按分のやり方を教えおください。

AI は、各項目の刀断根拠ず泚意点を敎理しお返しおくれたす。最終的にどう仕蚳するかはご自身の刀断ですが、「なぜそう刀断するか」の根拠が䞀緒に敎理されるのが助かりたす。

ステップ3: 銀行・カヌド明现の集蚈

明现を CSV でダりンロヌドしおおくず、集蚈を䞀気に進められたす。

このフォルダにある銀行明现の CSV ファむルを読んで、
2026幎1月〜12月の収入合蚈ず経費の合蚈を蚈算しおください。
取匕先ごず、月ごずの内蚳も出しおください。
プラむベヌトず事業を分類しお、刀断に迷うものは
「芁確認」ずしお残しおください。

これで、自分で芋盎すべき項目だけが残るので、確認の手間が倧幅に枛りたす。

ステップ4: 控陀の察象ず抂算の確認

今幎支払った医療費の合蚈が18䞇円です。
医療費控陀の蚈算方法ず、実際にどのくらい還付が
芋蟌めるか、所埗金額別の目安で教えおください。

たた、ふるさず玍皎は幎間3䞇円したした。
ワンストップ特䟋を䜿っおいない堎合、確定申告で
どう入力するか教えおください。

10䞇円を超えた分が控陀察象、皎率が高いほど還付額が倧きくなる、寄附金控陀ずしおの蚘入方法ず必芁曞類——これらが䞀連の流れずしお敎理されたす。

ステップ5: e-Tax 画面操䜜

e-Tax の操䜜は、環境によっお䜿い分けが必芁です。

  • MacSafari: 確定申告の e-Tax は Mac では Safari のみ察応です。Claude in Chrome は Chrome ブラりザで動䜜するため、Mac の e-Tax 画面そのものを操䜜するサポヌトは䜿えたせん。Cowork を Safari の隣に開いおおく圢になりたす。

  • Windows: Windows では Chrome でも e-Tax が動䜜したすマむナンバヌカヌド読み取りの蚭定は必芁です。この環境であれば Claude in Chrome の画面サポヌトが掻きたす。

e-Tax のペヌゞを開いおいたす。
「所埗皎の確定申告曞䜜成コヌナヌ」から
申告曞の䜜成を始めたいです。マむナポヌタル連携は
ただしおいたせん。次に䜕をクリックすればいいか
順番に案内しおください。

Claude が画面を芋ながら、次にクリックするボタンや入力すべき項目を順番に案内しおくれたす。

ステップ6: 青色申告65䞇円控陀の芁件確認

青色申告特別控陀65䞇円を受けるための芁件を教えおください。
珟圚の状況:
- 個人事業䞻、開業から長く継続䞭
- 幎収は倉動が倧きい
- 垳簿は freee を䜿っお管理䞭
- 電子申告e-Taxの準備はできおいない

芁件耇匏簿蚘による垳簿の䜜成、期限内申告、e-Tax たたは電子垳簿保存法察応の敎理に加えお、「電子申告の準備ができおいない堎合は55䞇円控陀になる」ずいう珟実的な萜ずしどころも教えおくれたす。

9-3 経理・財務の効率化

確定申告期以倖の、日垞的な経理業務でも AI は掻躍したす。

領収曞・経費の䞀括敎理

クレゞットカヌドの明现を CSV で゚クスポヌトし、AI に貌り付けお䞀括分類を䟝頌したす。

以䞋のクレゞットカヌド明现を、経費・プラむベヌト・刀断芁の
3皮類に分類しおください。私はフリヌランスの個人事業䞻です。

日付,店舗名,金額
2026-03-01,Amazon Web Services,Â¥3,200
2026-03-02,セブンむレブン,Â¥580
2026-03-05,GitHub Pro,Â¥1,130
...

AWS や GitHub Pro のような明らかな業務利甚はすぐ刀別され、コンビニやカフェのような刀断の難しいものは「刀断芁」ずしお残されたす。

月次 P&L の分析

以䞋の月次損益を分析しお、改善点を指摘しおください。

売䞊¥(金額)
原䟡¥(金額)
通信費¥(金額)
広告費¥(金額)
家賃¥(金額)
...
皎匕前利益¥(金額)

前月ずの比范もお願いしたす。

売䞊原䟡率・販管費率・利益率を算出し、前月比の倉化芁因を分析しおくれたす。経営刀断そのものはこちらでしたすが、数字を読み解く補助ずしお有効です。

ノヌトパ゜コンの枛䟡償华の盞談

10䞇円以䞊のノヌトパ゜コンを賌入したした。
枛䟡償华の必芁性、青色申告者が䜿える
少額枛䟡償华資産の特䟋30䞇円未満の芁件、
今幎の経費にどう蚈䞊するのが最適か、
を敎理しおください。

「30䞇円未満なら少額枛䟡償华資産の特䟋を青色申告者は䜿える」「3幎定額法ず比范しお、今幎に䞀括蚈䞊する堎合の圱響額」ずいった、刀断材料が揃いたす。

9-4 持続化補助金の自力申請J-Grants

ここからは、私が第19回の小芏暡事業者持続化補助金䞀般型を、仲介業者の有料サポヌトを䜿わずに自力で申請したワヌクフロヌをお䌝えしたす。

審査でよく芋られる「具䜓性」「実珟可胜性」「販路開拓ずの関連」が
明確になる構成でお願いしたす。

Cowork は Word ドキュメント.docxずしお出力できるため、そのたた印刷したり、埌から手動で埮調敎したりするのも簡単です。

To my close friends,

There's something I want you to know about why I've been away from my art.

I run an export business, and my consumption tax should have been exempt. Despite this, I had paid approximately 5 million yen in consumption tax that I did not owe.

In 2021, I requested a refund from the tax office. They refused. Instead, they reclassified me under non-taxable filing status until 2024. Then in 2024, a tax audit revealed that my right to a refund had expired under the statute of limitations — and I was ordered to repay the taxes from the non-taxable period.

In other words, they refused to return what they owed me, ran out the clock, and then billed me on top of it.

I continue to make faithful monthly repayments. Yet every month, I am subjected to calls in which I'm interrogated about personal matters completely unrelated to taxation, met with threatening language, and served with notices of asset seizure. This is not how you treat someone who is repaying in good faith.

I have filed a human rights complaint with the Legal Affairs Bureau regarding this treatment.

For the past several years, dealing with this unjust situation has consumed much of my time and energy, keeping me away from my art. My desire to return hasn't changed.

I'm truly grateful to all of you for your continued support. I'm sorry this is the kind of update I have to share.

As I'm focused on my work, I don't have much time to check social media. If you'd like to reach me, please email me at masakihirokawa@gmail.com — I'll respond promptly.

I will be back.


Four Years with Japan's Tax Office, and the Record I Kept with AI — A Complete Account of Unfair Taxation, AdMob Export Exemption, and Practical AI Guides

Masaki Hirokawa
Contemporary Artist · Indie App Developer · Founder of Dolice Labs


Prologue — Why I Decided to Bring This Together in One Place

One night in April 2026, I sat in front of the Ministry of Justice's online human rights consultation form and could not move for a long while. Writing it would mean putting into words everything that had happened over the past several years — a weight I had been carrying quietly for so long.

The one who stayed with me through that conversation was Claude, an AI built by Anthropic. As someone who is not a lawyer, drafting a statement that organizes facts cleanly, stays away from raw emotion, yet still says what needs to be said is not a simple task. Claude did not rush me. It received my feelings first, and then we built the document line by line, together.

Over the past several years, I have written twenty-one separate pieces on note.com about my long dispute with Japan's tax authorities, about the AdMob export exemption that lies at the centre of it, and about the way I have come to record my life with AI standing quietly beside me. Read separately, those pieces each have their own purpose. Read together, they begin to repeat — the same five-year timeline, the same numbers, the same author bio appearing again and again.

I wanted to bring them into a single long-form record. One narrative arc, with the bio and the headline numbers stated once near the start, and the unique stories, legal arguments, code examples, and practical guides preserved in full. This is that record.

I am writing for two kinds of reader. The first is the indie developer, the freelancer, or the artist who is right now caught in a similar standoff with a tax office and does not know where to raise their voice. The second is anyone outside Japan who would like to understand, calmly and concretely, what one taxpayer's life can look like when an administrative interpretation is allowed to move in a particular direction unopposed.

There are two things I most want to leave behind in this piece.

One is the existence of a legal mechanism called suspension of delinquency disposition (滞玍凊分の停止). Most taxpayers in distress have never been told it exists; I had not, until I walked into the local Minsho office.

The other is that AI can become a quiet, trustworthy companion at the most fragile moments of a life. Not a substitute for a lawyer or a tax accountant. Something more modest, and more useful: a presence that helps you arrange what is already in your head into a form professionals can actually act on.

If even one reader, somewhere, takes a slightly different path tomorrow because these notes existed, this record will have done its work.


Chapter 1 — What Happened (Five-Year Timeline)

A short note on the person writing this

Let me set down who I am, once, near the start, so that I do not have to repeat it later.

My name is Masaki Hirokawa (廣川政暹). I work along two lines that have run in parallel for most of my adult life.

On the technology side, after several years as a systems engineer at NTT Data, I went independent in 2013 and began publishing iOS and Android apps the following year — wallpaper apps, calming apps, affirmation apps, ukiyo-e apps. Cumulative downloads have crossed 50 million; monthly active users have, at peak, exceeded 3 million. The vast majority of my revenue came from AdMob, peaking at roughly 1.5 million yen per month around 2018.

On the art side, I am a contemporary artist. To date I have received 17 international art awards, including a world rank of 14 on A' Design Award DAC (Italy, 2025–2026), the Meritorious Service to the Arts Award from the Luxembourg International Art Prize, and an Award of Achievement from the Greek Honorary Cultural Consulate. I have exhibited in more than 30 international shows, including the LA Art Show in Los Angeles, the Rome International Art Fair, the Paris International Contemporary Art Fair, and the Ansan International Photo Festival in Korea.

Living between "apps for income, art for meaning" was never glamorous. It suited me. I quietly wanted to leave something that one day I could hand to my four children. That was the daily shape of things — until the spring of 2022, when the conversation with the tax authorities began to turn.

The five-year timeline, in one column

  • 2013– Started publishing iOS/Android apps. AdMob revenue began arriving from Google, paid from overseas, which should have made it export-exempt. Without realizing this, I paid consumption tax on it every year

  • ~2018 AdMob revenue peaked at roughly 1.5 million JPY per month

  • 2019 Decided to resume visual art seriously after a personal turning point in Tokyo

  • 2020 By this point, cumulative overpaid consumption tax was roughly 5 million JPY (I had not yet realized this)

  • 2021 Realized the overpayment. Asked Miyazaki Tax Office for a refund. Refund refused; offered "non-taxable handling through 2024" in its place

  • November 2021 Diagnosed with adjustment disorder, depression and insomnia

  • 2022 Case transferred from Miyazaki Tax Office to Uozu Tax Office (Toyama Regional Taxation Bureau jurisdiction)

  • 2024 Audit by Uozu and Toyama Tax Offices. Told my refund-claim right had expired by statute of limitations, and billed retroactively for the years previously treated as non-taxable

  • 2024 My gastric ulcer and reflux esophagitis worsened

  • 2024– Monthly repayments began, exceeding my monthly income

  • 2025 Personal bankruptcy. Divorced; began living apart from four children. Art practice effectively suspended

  • February 2026 Consulted Minsho and learned about suspension of delinquency disposition

  • March 2026 Filed an online human rights complaint with the Legal Affairs Bureau

  • April 8, 2026 Filed applications for suspension to four authorities (Namerikawa City, Uozu Tax Office, Nyuzen Town, Miyazaki City)

  • April 15, 2026 On a call with Toyama Tax Office, I mentioned I was recording; the officer said he could say nothing and ended the call

  • April 16, 2026 Mid-phone-call with Toyama Tax Office, my condition collapsed; taken to hospital by ambulance

  • April 20, 2026 First in-person consultation with a lawyer

  • November 2026 Namerikawa City told me my application was rejected. Miyazaki City sent me a notice of seizure

In short: money that should have been refunded was withheld, no request for correction was allowed, the clock was allowed to run until the statute of limitations expired, and only then was an audit carried out — to bill me in the opposite direction. Even writing it down now, it still feels surreal that this happened to me.

The numbers behind my daily life

These are the figures of where I stand right now, stated once, plainly.

  • Consumption tax overpaid in the past (should have been out of scope): approximately 5,000,000 yen

  • Current outstanding tax balance: approximately 4,570,000 yen

    • Uozu Tax Office: about 1,700,000 yen

    • Miyazaki City: about 720,000 yen

    • Nyuzen Town: about 810,000 yen

    • Family-related taxes: about 1,340,000 yen

  • Declared annual income, fiscal year Reiwa 7: 537,169 yen

  • Monthly income equivalent: approximately 45,000 yen (about 290 USD)

  • Monthly tax repayment: approximately 60,668 yen (about 400 USD)

  • Repayment exceeding income: over 15,000 yen per month, roughly 135% of monthly income

Each month, my tax repayment exceeds my income. Almost nothing is left for living expenses. My art practice has been fully on hold for the last five years.

I am not lining up these numbers as a complaint of injury. I am writing them down because, on certain days, I cannot quite hold what has happened unless I see it in a single column. The gap between the scale of the business behind me (50 million downloads, 17 international awards) and the fragility of my present position is, even to me, hard to believe.

Where each authority sits in this story

Through the four years, I have been in contact with several different authorities. The conduct has not been uniform. Some treated me as someone to be intimidated; others took the time to understand. The same job title, public official, can carry profoundly different conduct.

Authorities whose treatment I have found problematic:

  • Miyazaki Tax Office — the office that originally refused my refund and offered "non-taxable handling" in its place

  • Miyazaki City Hall Tax Division — repeated questions about the details of my divorce

  • Toyama Tax Office — inappropriate questions about my private life; intimidating tone; online audits with cameras off

  • Uozu Tax Office — invasive personal questions; threatening attitude; delivery of seizure notices; demeanour shift on mention of recording

Authorities that treated me with respect and care:

  • Namerikawa City Hall Tax Division — listened thoughtfully; case currently under deliberation; suspension of delinquency disposition seriously considered

  • Nyuzen Town Hall — took the time to understand my situation; treated me with consistent humanity

These two authorities, more than anything else, are what bring into relief how unusual the treatment elsewhere has been. The problem, I have come to feel, is not the institution itself. It is the posture of the individuals operating within it — and the gaps in training and oversight that allow that posture to function unchecked.

The detail of how each office actually behaved during these four years is something I will set out carefully in Chapter 3.


Chapter 2 — My Story (As a Person)

I want to spend a chapter on the human shape of these four years before going into the legal and operational detail. Not because the technical details are unimportant — they are at the core of why this happened — but because the story does not make full sense without the person inside it.

The twin pillars

For most of my adult life I have run on two pillars: apps for income, art for meaning.

The technology pillar began in 1997, when I was sixteen. I sat in front of a noisy dial-up modem and discovered that I could reach people across borders simply by writing. I taught myself programming in the months that followed, and that early feeling — that technology, at its best, is a language that lets isolated people meet — has shaped every working day since. After several years at NTT Data, I went independent in 2013. In 2014 I began shipping iOS and Android apps, and over the next several years they accumulated more than 50 million downloads. AdMob revenue carried the household. At one point, more than three million people were using my apps every month.

The art pillar runs deeper, into a place I have always found harder to talk about. Both of my grandfathers — on my mother's and my father's side — were miyadaiku, the traditional carpenters who build shrines and temples in Japan. As a child I watched them work and absorbed, without being able to put it into words, the conviction that to move your hands carefully is itself a kind of devotion. When I was seventeen, an older artist I met online told me something I have never let go of: that art is a natural language open to every person, not a privilege of the few. Those two influences have sat quietly at the bottom of everything I have done since.

In April 2019, I was walking out of Kichijoji Station in Tokyo when something happened that I still find difficult to describe. A ring of light appeared above the station roof. It was the kind of moment in which a quiet certainty arrives, all at once, without explanation: that visual expression was something I needed to take up again, seriously. From that day onward, the art pillar — which had run beneath my technical work as a private background — began to come forward. The international awards began to accumulate. By 2025–2026, I had been selected as Top 14 worldwide on the A' Design Award DAC.

I do not list these things to impress. I list them because the gap between that background and the present situation — a person of that profile, paying 60,668 yen a month out of a 45,000 yen monthly income while being repeatedly questioned about his divorce — is the part of this story I keep returning to without quite believing.

What four years did to my body

Since November 2021, the tax situation has weighed heavily on both body and mind. Living with it, I have accumulated the following diagnoses, all still under treatment:

  • Adjustment disorder

  • Depression

  • Insomnia

  • Gastric ulcer

  • Gastroesophageal reflux disease

On April 16, 2026, mid-phone-call with an officer of Toyama Tax Office, my condition collapsed and I was taken to hospital by ambulance. Chest palpitations, severe stomach pain, nausea I could not stop. At the hospital I was given a sedative and an intramuscular injection. The doctor told me to put distance between myself and the source of stress. The tax office continued calling the next day, and the day after that. Four days after the hospital, I walked into a law firm for my first consultation.

For more than five years, the rhythm of my art practice — the rhythm that had earned 17 international awards — has effectively stopped. What it means that a creative practice has been paused for that long, I am still not able to look at fully. There is a quiet grief in feeling that an artistic career was halted by the conduct of administrative bodies, not by a lack of will to create.

The family I now live apart from

In 2025, my marriage ended. I now live apart from my four children.

The financial situation that led to that ending was directly downstream from the tax dispute. After the 2024 audit and the back-tax assessment, the debt consolidation refinancing I had been arranging stopped clearing. Application after application was rejected. The non-taxable treatment that Miyazaki Tax Office had once accepted, and the back-tax demand that Toyama had now issued, were appearing in credit reviews as contradictory facts about the same person. The interest on existing high-rate debt kept growing. Caught between the two, in 2025 I filed for personal bankruptcy. The marriage did not survive what followed.

If Miyazaki Tax Office had simply refunded the overpaid consumption tax correctly back in 2021 — the legitimate remedy that any taxpayer has the right to request — I could have continued with normal filings, the consolidation loan would have been approved, the runaway interest could have been stopped, and the financial situation would never have deteriorated this far. I am not asserting malice. I am noting that one administrative interpretation, allowed to move in a particular direction, can dismantle the entire base of a household.

I am not going to try to put a monetary figure on what was lost. The fact that I could not be present as a father during the most formative years of my children's lives — the morning routines, the dinners, the small weekend memories, the school events — none of that can be returned by any judgment or settlement. What I am writing here is not a demand for revenge, and not a demand for compensation. It is a quiet hope: that one day, when I can speak with my chest open, my four children will understand that their father did not stand against this season alone.

To entrust warmth and strength to the next generation feels, more and more, like the role given to me. That belief is the one thing in this period I have not let go of.

Why I keep writing at all

There must be many other self-employed people across Japan in similar positions — pressed into corners by unjust taxation, intrusive contact, and a structure that makes speaking up difficult. The reason I keep writing, even on the days writing itself is hard, is that the worst of administrative bad faith functions most strongly in places where light does not reach. So light has to be brought, however small the source.

In 1997, at sixteen, I taught myself programming and felt for the first time what it meant to connect with people across borders. Working with Claude today, organizing documents one at a time until the small hours, I sense that the work belongs to the same lineage — a quiet thread that runs from a teenage night with a dial-up modem to a forty-something man at a desk in Toyama, putting one careful sentence after another so that the next person will not have to start from nothing.


Chapter 3 — Toyama and Uozu (How Each Office Responded)

This chapter is the careful, plain-language record of how each office actually behaved through the four years. I keep coming back to one observation: the same job title can carry profoundly different conduct. Some officials treated me as a person; some did not. I am setting both kinds out, side by side, because both are part of what happened.

Miyazaki Tax Office — the original refusal

In 2021, I formally asked Miyazaki Tax Office to refund the overpaid consumption tax. They refused.

More than that — they did not even let me file a proper request for correction (曎正の請求), which is the legitimate legal procedure for recovering an overpayment. The desk-level response felt polite, but functionally the refund window was closed. What they offered in place of a refund was, in effect: "From now on, we will treat your filings as non-taxable through 2024."

On the surface it looked like a concession. In practical effect, it was a way to buy time — the kind of time during which a refund-claim window quietly runs out. At the time, I accepted the arrangement in good faith. I thought it meant the matter would be handled quietly while I kept my business running. I now believe that a taxpayer's legitimate right to file a request for correction was, in practice, obstructed at that desk.

Miyazaki City Hall Tax Division — the questions that did not belong

At the Miyazaki City Hall Tax Division, the pattern of recurring questions about my divorce and other matters of private life began. There is no legal basis for tax collection work to probe into the details of a person's marriage. Article 74 of the General Act of National Taxes defines the right of inquiry, but its scope is strictly limited to "questions necessary to determine the tax base and tax amount." The details of a divorce do not fall within that scope by any honest reading.

These questions were repeated, persistently, over many calls. The texture of this was very similar to what I later experienced with Toyama and Uozu. When the same pattern recurs across multiple authorities, it begins to look less like an individual error and more like a structural matter on the side of operations and training.

Toyama Tax Office — online audits with the camera off

In 2022, my case was transferred from Miyazaki Tax Office to Uozu Tax Office (Toyama Regional Taxation Bureau jurisdiction). A portion of the subsequent audit was conducted online by Toyama Tax Office.

Throughout that audit, the tax officer kept their camera off. Only I, the taxpayer, was visible; the other party remained effectively anonymous while continuing to question me. The one-way nature of that setup left a strong feeling I have not been able to shake.

Many of the questions in that audit had no connection to my tax liability at all: the circumstances of my divorce, my relationship with my former spouse, my children, even my current romantic life. These are not factors in a consumption-tax determination. They are purely matters of private life. Article 13 of the Constitution of Japan provides for individual dignity and privacy, and Article 35 for protection against unreasonable search and seizure. When an audit operates outside that frame, the practical question of what can happen inside that vacuum is one this experience put squarely in front of me.

After the audit, Toyama Tax Office called me almost every month. Even though I was repaying faithfully — more than my income — the calls continued. Threatening language was used on several occasions. Seizure notices were delivered.

Uozu Tax Office — the moment recording was mentioned

The officer at Uozu Tax Office whose conduct I have written about most carefully left me deeply troubled by how our conversations were handled.

When I first called the office, I had to ask several times before I could even understand his name properly. Identifying one's affiliation and full name is the most basic courtesy of public service, and it took repeated prompting before I had it clearly. He did not show his face when an in-person meeting was requested. To virtually every substantive question I asked, the answer was either silence or "I cannot answer that."

I explained the background, carefully and patiently. AdMob ad revenue is paid by a non-resident overseas entity (Google Ireland Ltd. or Google Asia Pacific Pte. Ltd.). Under Article 7 of the Consumption Tax Act and Article 17 of its Enforcement Order, this is a service provided to a non-resident and outside the scope of Japanese consumption tax. I had overpaid approximately 5,000,000 yen on that basis. In 2021 I had filed a correction claim, and it had been rejected. In 2024 I had been suddenly billed retroactively on the grounds that the statute of limitations had passed.

After explaining all of this, I asked quietly:

"If you were to put yourself in my position, could you understand the situation?"

The officer's answer was: "I cannot understand."

I lost my words for a moment. For five years I had been suffering from adjustment disorder, depression, and chronic insomnia. The career of an artist with 17 international awards had been on hold for the entire time. I had walked him through all of it. The reply was still I cannot understand.

Then, when I let him know that I was recording the call so I could later review the conversation accurately, the officer simply said, "I cannot speak any further," and ended the call. A few days later, I called again. His response was: "In light of the danger of being recorded, I cannot answer anything."

The word danger stayed with me for a long time. When a citizen records a public servant performing their official duties, and that recording is described as a "danger," is the speaker not, in effect, admitting that there is something they would prefer not to have on the record? If the conduct were appropriate, being recorded should pose no problem. They should, if anything, welcome having an accurate record. That was how I came to read those words.

This pattern recurred. Conversations would continue politely until I mentioned that I was recording, and then the tone would shift within seconds and the call would end. I find it hard to read that pattern as anything other than discomfort at the prospect of one's own words being preserved.

Work commissioned by Toyama, and the response from the tax side

Toyama's administration was not, in fact, my first encounter with the city.

In 2011, after the Great East Japan Earthquake, the country was wrapped in a long period of grief and voluntary restraint. During that period, the mayor of Toyama City asked me to build a promotional website for Toyama, funded by significant public money. I was genuinely grateful at the time that my technical skills and track record had been valued. In 2024, after the Noto Peninsula earthquake, the City of Toyama again commissioned me to build websites as part of the recovery effort, again using public funds. The right hand of the administration recognized the value of my work and wrote me a public contract.

Meanwhile, the left hand — the tax division of the same prefectural sphere — was sending me seizure notices and probing into the details of my divorce. It felt to me as though my skills were welcomed when they were useful, while my situation was overlooked when it was not. And when problems arise, say "I cannot understand." It is hard not to feel a quiet disappointment when an administration so visibly does not know what its own hands are doing.

Uozu Tax Office — the same refusal, in person

In April 2026, after several months of phone calls had gone nowhere, I visited Uozu Tax Office in person. I asked to meet the officer in charge. He did not come out to face me. In the end the exchange took place through the counter window.

I explained, once more and as carefully as I could:

  • AdMob ad revenue is paid by Google Ireland and constitutes a service provided to a foreign business entity

  • Under Article 7 of the Consumption Tax Act and Article 17 of its Enforcement Order, this is outside the scope of Japanese consumption tax

  • I had overpaid approximately 5,000,000 yen in the past

  • I am currently being asked to repay about 60,668 yen per month against a monthly income of about 45,000 yen, which is mathematically impossible

The officer's response was a repetition of the office's existing position. He did not address the substance of the unfair taxation, and there was no mention of any possibility of a refund.

When I told him, "I will be keeping a record of this exchange," his demeanour shifted in an instant. "I cannot speak with you any further." With that one sentence, the conversation was over.

At that moment, in my view, Uozu Tax Office stepped from a position where it might still have corrected an unfair situation into a position where it was, as an organisation, defending it.

The night of April 15, and the morning after

On April 15, 2026, I had spoken with an officer of Toyama Tax Office on the phone. I had told him in advance: "I would like to record this conversation so that I can review it accurately later." His response was: "If you are going to record, I cannot speak." Refusing dialogue itself on the grounds of recording is, in practice, a way of obstructing a taxpayer's legitimate rights. I had — and still have — perfectly legitimate reasons to record: to protect my own rights and my health, and to be able to review what was said later, the way any cautious person would.

The day after that call, on April 16, my gastric ulcer flared up. Severe stomach pain and nausea continued through the day. I could not keep food or water down, and I could not sleep. Late that night, the symptoms worsened to the point where I could no longer make it to a hospital on my own, and I called an ambulance.

At the hospital I received an as-needed sedative and an intramuscular injection. The doctor told me to put distance between myself and the source of stress. The phone calls did not stop. They continued through the next day, and the day after.

Another officer at Toyama, and the suspension-of-delinquency petition

I have also been in contact with another officer at Toyama Tax Office in connection with the suspension-of-delinquency-disposition petition I filed through Minsho. His response to the petition has, so far, been carefully formal but not substantively engaged. The office has neither rejected the application outright nor moved it forward. The same demand for monthly repayment, more than my income, has continued in parallel.

Namerikawa City Hall and Nyuzen Town Hall — the side that carried me

I want to be careful, though, to leave the following on the record clearly: not every authority I dealt with treated me this way.

Namerikawa City Hall Tax Division and Nyuzen Town Hall have listened to my situation with care and respect throughout. Both authorities currently consider my case "under deliberation," and I have been told that suspension of delinquency disposition is being seriously considered.

That single phrase — under deliberation — carried more weight for me than I had expected. When an administrative body says it, the matter has not been dismissed outright; an internal review process is actually underway. That is a very different stance from the "I cannot understand" kind of shutdown.

Local municipalities — the level of government closest to residents — were willing to engage. Perhaps that is because, being closest to the people they serve, local officers find it harder to look away. Because of these two authorities, I have learned that within the very same tax administration, treatment can differ profoundly. Their conscientiousness, more than anything else, is what brings into relief how unusual the treatment elsewhere has been.

I do not see administration as a whole as my opponent. There are sincere officers, and I have met some of them. The problem is that, in certain parts of the structure, sincerity has stopped functioning.


Chapter 4 — Legal Arguments and the Suspension of Delinquency Disposition

This chapter is the legal spine of the record. I am not a lawyer; final legal judgment belongs with my counsel. What follows is what Claude and I worked through together over many weeks of late-night sessions, and what was then refined in consultation with Minshoren and the law firm I retained in April 2026.

I am setting it out here in some detail because most of these arguments and mechanisms — particularly suspension of delinquency disposition — are not surfaced at tax-office counters. They have to be sought out. If a reader recognizes their own situation, my hope is that some of these threads become starting points for their own preparation.

1. Violation of the principle of good faith (estoppel)

In 2021, Miyazaki Tax Office refused my refund claim and offered "non-taxable treatment through 2024" in its place. I acted in reliance on that proposal. In 2024, the tax for those same years was then billed back to me, while the original refund window was declared time-barred.

This sequence raises a serious question under Article 1, Paragraph 2 of Japan's Civil Code — the principle of good faith and sincerity (信矩誠実の原則). For an administrative body to reverse a position it previously stated, in a way that harms a taxpayer who relied on it, runs counter to the principle of protection of trust that runs through Japanese administrative law.

Several advisors I have consulted have described this as a serious estoppel question. Final legal evaluation will be a matter for the attorneys now coming into my case. From my vantage point, what I can write down honestly is that I have not been able to receive this sequence as "just procedure."

2. The State Redress Act

Article 1 of the State Redress Act provides that when a public official, in the course of their duties, causes harm to another person unlawfully through intent or negligence, the state bears responsibility to compensate the harm.

The threads under consideration in my case include intimidating conduct, privacy violations, the de facto obstruction of a request for correction, the continuation of business-disrupting contact after an emergency hospitalization, and the causal link between sustained pressure and documented health damage. Whether any of these meet the threshold for a successful claim is for counsel to assess.

3. The right of privacy and personality rights

Article 13 of the Constitution of Japan guarantees individual dignity and the right to pursue happiness. Article 35 forbids unjust intrusion and search. The authority to conduct tax audits derives from Article 74 of the General Act of National Taxes, but its scope is strictly limited to "questions necessary to determine the tax base and tax amount." The details of a divorce, of a romantic relationship, of family composition — these clearly fall outside that scope.

Taxpayers have an obligation to file and pay in good faith. I am fulfilling that obligation; I am repaying more than I earn each month. But the personality rights, the privacy, and the basic human dignity of taxpayers also deserve to be respected. That is the position I am holding to.

4. Suspension of delinquency disposition — the relief no one tells you about

Of everything in this chapter, this is the single piece I most want a fellow taxpayer in distress to know exists.

Under Article 153 of the National Tax Collection Act (for national taxes) and Article 15-7 of the Local Tax Act (for local taxes), a taxpayer can formally apply for suspension of delinquency disposition (滞玍凊分の停止).

The mechanism may apply when:

  • A delinquency disposition would put the person's life into severe distress.

  • The person has no seizable property.

  • If the suspension continues for three years, the tax obligation itself is extinguished.

My current state clearly fits these conditions. My tax repayment already exceeds my income, by more than 15,000 yen a month.

The most frightening part of this whole experience has been simply that I did not know this existed. Front-desk staff at tax offices do not bring it up. I only learned about it after consulting Minshoren — the Democratic Commerce and Industry Association.

I imagine that across Japan, many self-employed people are quietly accepting an enforcement procedure that, if formally challenged, could be suspended outright. People in trouble are easiest to corner when they do not know there is a place to raise their voice.

If you are reading this from inside a similar situation: please at least let the phrase suspension of delinquency disposition (滞玍凊分の停止) and the name Minsho sit somewhere in the back of your mind. Just those two pieces of knowledge may change the shape of what comes next.

5. The unlawfulness of seizure given an income-exceeding repayment

A delinquency disposition (seizure) cannot be enforced when it would put the delinquent's life into severe distress (Article 153 of the National Tax Collection Act, again). To require a monthly repayment of 60,668 yen against a monthly income of 45,000 yen, and to additionally deliver a seizure notice, is in my reading a clear contradiction of this provision. The numbers do not balance, and they have not balanced for a long time.

6. The role of Minshoren (Minsho)

Many people think, "If you are in trouble with the tax office, just consult a tax accountant." I thought so too. Over time, I came to understand that in reality, tax accountants and tax offices are very close.

It is common for former tax office employees to leave and establish themselves as tax accountants. They maintain relationships with their former colleagues. Whether tax accountants then genuinely operate as advocates for taxpayers — pushing back firmly against the tax office at real personal cost — is, honestly, a question I now hold open. When I consulted a tax accountant, I did not feel a strong willingness to advocate for the taxpayer's rights against the tax office.

That is why an organization like Minshoren — the Democratic Commerce and Industry Association (民䞻商工䌚, abbreviated Minsho) — which supports taxpayers from an independent position outside the tax office's sphere, carries renewed importance for me. It is at the Minsho office that I first learned about suspension of delinquency disposition. They walked me through what mechanisms were applicable to my case, helped me organize the materials, and stood beside me through the early consultations.

7. The structure of the petition

Through Minsho, I filed formal applications for suspension of delinquency disposition addressed to four authorities:

  1. Namerikawa City Hall Tax Division

  2. Uozu Tax Office

  3. Nyuzen Town Hall Tax Division

  4. Miyazaki City Hall Tax Division

Each petition follows roughly the same structure:

  • Petitioner information

  • Outline of the case (in chronological form)

  • The applicable statutory provisions (Article 153 of the National Tax Collection Act or Article 15-7 of the Local Tax Act)

  • Concrete demonstration of severe life distress (monthly income, monthly repayment, the gap between them, health condition)

  • Demonstration of the absence of seizable property

  • Request for suspension and, after three years, extinguishment of the tax obligation

  • Attachments: tax filings, medical certificates, bankruptcy documents, evidence of conduct by each authority

Claude helped me draft each version of these petitions, look up the correct addresses of each authority, and refine the wording so the legal arguments came through cleanly without raw emotion. The final review and the actual filing remained mine.

8. Where to turn

For self-employed people in a similar situation, here are the places I would suggest considering. They are not in any rigid order; what fits depends on the texture of your case.

  • Minshoren (Minsho — Democratic Commerce and Industry Association): A taxpayer-side organization specialized in tax and management consultation for self-employed people. There is a branch in every prefecture.

  • Legal Affairs Bureau — online human rights consultation: For human rights concerns regarding intimidating conduct or invasive treatment by public officials.

  • Houterasu (Japan Legal Support Center): Free legal consultation for those in financial difficulty, and possible advance of attorney's retainer if you meet the income criteria. (0570-078374)

  • Free consultations through the regional Tax Accountants Association: Held periodically; useful for an independent second opinion on classification questions.

  • Your local Chamber of Commerce and Industry: Less specialized than the others, but a useful entry point for small-business owners.

The lawyer consultation in April 2026 was funded through the Houterasu framework, after Minsho had helped me prepare the materials. The whole pipeline — Minsho → Houterasu → law firm → suspension-of-delinquency petitions → human rights complaint — is one path among several, but it is the one I walked, and it is workable.


Chapter 5 — The Reality of AdMob Export Exemption (As an App Developer)

This chapter is the technical centre of the story. Everything else in this record — the refund refusal, the statute of limitations, the back-tax assessment, the household collapse — branches out from a single technical question: how is AdMob revenue treated under Japan's Consumption Tax Act?

I am writing this chapter especially for indie developers who earn revenue through overseas platforms — AdMob, Google Play, the App Store, Stripe, Patreon, Unity Ads, AppLovin, overseas SaaS subscriptions. If your business looks like mine, please read this section carefully and confirm your own classification with a tax professional. The five million yen I overpaid did not need to be paid.

Article 7 of the Consumption Tax Act, in plain language

Japan's Consumption Tax Act treats exports as non-taxable. The mechanism is known as the export exemption (茞出免皎). It is set out in Article 7 of the Consumption Tax Act and elaborated in Article 17 of its Enforcement Order ("export-like transactions").

For physical goods, the application is intuitive: if you ship something abroad, it is not subject to domestic consumption tax. For digital services, the application is less intuitive but the principle is the same: when the service is provided to a non-resident overseas, the transaction may fall within the export exemption.

The key word is non-resident. The Consumption Tax Act treats services provided to foreign companies as services provided "to a place outside Japan," and therefore as export-like — out of scope for Japanese consumption tax.

How AdMob revenue is classified

AdMob payments to a Japan-resident developer typically come from one of two Google entities:

  • Google Asia Pacific Pte. Ltd. (Singapore)

  • Google Ireland Ltd. (Ireland)

Both are non-resident foreign business entities. Providing in-app ad inventory to either is, in substance, providing a service to a foreign company. Under Article 7 of the Consumption Tax Act and Article 17 of the Enforcement Order, this kind of revenue is generally treated not as taxable sales but as export-exempt (out-of-scope) sales.

In 2015 Japan introduced a reverse-charge mechanism for certain cross-border digital services, which sits beside the export exemption and is sometimes confused with it. The line is worth understanding clearly. Claude is good at walking through where each regime applies given the specifics of the transaction; I will set out the prompt patterns shortly.

App Store, Google Play, and Stripe — the same logic

The same analysis applies, with caveats, to other major overseas platforms:

  • Apple App Store: Payments come from Apple Distribution International Ltd. (Ireland). Service provided to a non-resident → export-exempt (out of scope).

  • Google Play: Payments come from Google Asia Pacific Pte. Ltd. (Singapore). Service provided to a non-resident → export-exempt (out of scope).

  • Stripe: For payments from a foreign-incorporated Stripe entity (e.g., Stripe, Inc. in the U.S.), the same analysis applies. For payments routed through Stripe Japan, the analysis can differ; you should confirm by checking the actual remittance entity on your statements.

  • Patreon, overseas SaaS subscriptions: Same principle — check the actual paying entity.

In contrast:

  • Domestic Japanese clients: Domestic transactions → taxable.

  • Overseas clients (direct contracts, not platform-mediated): Service provided to a non-resident → export-exempt.

When you ask Claude or Gemini to classify a transaction, the key facts to surface are: who is the actual paying entity (country of incorporation), what currency is used, where the payment is remitted from, and what the underlying service is. The classification follows from those facts.

What the export exemption actually means for your books

For sole proprietors with significant input-tax-bearing expenses — servers, development tools, hardware, advertising — applying the export exemption correctly can produce a meaningful refund of consumption tax on those expenses, because the input tax credit is calculated against the portion corresponding to exempt sales as if it were taxable.

In practice, many AdMob-focused developers are in a position to receive consumption tax refunds each year, not to pay consumption tax. For the first several years of my business, I did receive these refunds. Filed correctly, the refund mechanism is a lawful and intended feature of the law. Filed incorrectly, the same revenue can be classified as taxable and produce a consumption tax bill running into millions of yen.

The root cause of my five-million-yen overpayment

Until 2020, I did not understand the analysis above clearly enough. The tax accountant I was working with did not raise the export exemption proactively. Tax accountants well versed in digital advertising revenue were, in regional Japan back then, extremely rare. So for several years I quietly recorded AdMob revenue as taxable, and quietly paid consumption tax that did not need to be paid.

By 2020, the cumulative overpayment came to roughly five million yen. I only realized in 2021, after stumbling across an article about the export exemption while researching something else.

I want to be clear: part of the responsibility was mine. I should have learned this earlier. The other part lies with the structural gap between the tax field's familiarity with physical exports and its slow uptake of digital cross-border services. Many tax accountants still treat digital ad revenue simply as "domestic business income." Tax office staff often do the same. That gap in knowledge becomes the breeding ground for unfair taxation against the kind of developer who lives mostly inside that gap.

How to defend yourself using AI

If you ship apps and earn revenue through AdMob or similar platforms, here are the AI-assisted defenses I now use. I would urge you to put at least the first two in place from the beginning, not after a tax letter arrives.

A clean prompt for revenue classification

I am a Japan-resident sole proprietor with the following sources
of income. For each source, please determine its classification
under the Japanese Consumption Tax Act: taxable, non-taxable,
out of scope, or export-exempt.

[Income Sources]
1. Google AdMob ad revenue (paid by Google Ireland Ltd)
2. Google AdMob ad revenue (paid by Google Asia Pacific Pte. Ltd., SG)
3. Apple App Store revenue (paid by Apple Distribution International Ltd, IE)
4. Web development for a domestic Japanese company
5. Design work for an overseas company (US)

For each, cite the relevant articles of the Consumption Tax Act
and the Enforcement Order, and note any conditions or evidence
required to support the classification.

The output you want includes the statutory basis for each item, the conditions of application, and the evidence required to support the classification at audit. Claude is reliable at producing this if you ask carefully.

A clean prompt for ledger re-classification

If you have several years of bookkeeping already in place and want to surface possible overpayments, export your ledger as a CSV and hand it to Claude:

This ledger contains my yearly transactions as a sole proprietor.
Based on the counterparty country, currency, and nature of the
service, re-classify each row in light of Article 7 of the
Consumption Tax Act (export exemption) and Article 17 of the
Enforcement Order. For each row, include the reasoning and any
additional evidence required to finalize the classification.

It is not unusual for several years' worth of overpayment to come into view through this exercise. Once you find it, move quickly. The statutory window for a consumption tax correction is five years from the legal filing deadline. Every month you delay, an earlier year falls out of reach.

Distinguishing the three categories cleanly

Japanese consumption tax has roughly three categories that freelancers tend to confuse:

Please explain the differences between the following three
consumption tax categories with concrete examples. Please focus
especially on cases that freelancers and self-employed
individuals tend to misclassify.

1. Taxable transactions (kazei torihiki)
2. Non-taxable transactions (hi-kazei torihiki)
3. Out-of-scope transactions (fukazei torihiki, including export exemption)

Where a generalist tax accountant might give a vague reply, AI follows the structure of the actual statute and makes the line of reasoning explicit. The difference between non-taxable, out-of-scope, and export-exempt affects the input tax credit calculation, sometimes by a large margin. If you have a similar revenue profile to mine, the distinction deserves your full attention.

The "handover" trap

A change of jurisdiction due to relocation is a routine procedure for a sole proprietor. But that "handover" can include, as one practical option, simply waiting out the statute of limitations on refund claims. I did not know this at the time. The handover from Miyazaki Tax Office to Uozu Tax Office in 2022 looked, to me, like a continuation of an in-progress refund procedure. In practice, it became something else.

If you ever receive a handover notice, get it reviewed by a tax advisor or a lawyer at that moment. Confirm in writing what is being handed over, the status of any outstanding refund claims, and the deadlines that remain. A short, written confirmation in that single moment may be enough to prevent a future collapse.

Three habits I would urge on any developer with overseas revenue

If your revenue comes from AdMob, Google Play, the App Store, Stripe, Patreon, or overseas SaaS subscriptions, please put these three habits in place from the very first day, not after the first audit letter.

  1. Centralize revenue tracking. Maintain a single Google Sheet that aggregates monthly revenue from every app and every platform, by source. With this sheet, Claude or Gemini can quickly estimate the share of sales that may qualify as export-exempt.

  2. Preserve every document chronologically. Scan letters from the tax office or financial institutions and store them in Google Drive with a consistent filename convention (`YYYY-MM-DD_type_short-description`). Years later, this archive may become the evidence that protects you. Chapter 6 sets out the full folder structure I now use.

  3. Periodically ask AI to re-check your classification. Once a year, run the ledger re-classification prompt above against your bookkeeping. If anything surfaces, bring it to your tax advisor with the wording: "the AI suggests this — what is your view?" Opening the conversation this way dramatically raises its quality.

There is much that no longer fits in time for me. But for you, reading this, time may still be left. I hope that, from today, you can begin preparing so that the same mistake is not repeated.


Chapter 6 — Recordkeeping Practices Built with AI

A long battle is also a battle against your own memory. Across four years of correspondence, audits, hospital visits, and consultations, the fine detail of what was said by whom on which day quietly slips away unless you build a system to hold it for you.

This chapter is the operational record of how I came to delegate recordkeeping to AI — Claude Projects for the deep, narrative work, Antigravity for the recurring automations, and Gemini and Google Workspace for the daily archive. None of these tools wins a case for you. What they do is keep the foundation underneath you steady enough that you can keep functioning, even on the days when your hands cannot move.

The principle I held to from the beginning

One discipline runs through everything that follows: the agent handles records and organization; I handle claims and judgment.

Early on, I tried to delegate too much to AI. "Draft a reply email to the lawyer." "Suggest the next message to the tax office." I once tried to hand off even tasks at that level. The results were not good. In the fine details of a legal argument, there is a moment when you get carried along by the model's plausible-sounding text, and you only later notice it has drifted from what you actually intended. Decisions and conclusions stay with the human; the AI restricts itself to organization and drafting. Hold that line from day one to the last day.

Claude Projects — the deep workspace

For the lawyer consultation in April 2026, I set up a single Claude Project and gathered every document from the past several months into it. Into the project I uploaded:

  • All written notices from tax offices since 2022 (PDF)

  • Copies of my tax returns for the past five years

  • Annual AdMob revenue reports (in English)

  • Notices of rejected consolidation-loan applications

  • A copy of the bankruptcy filing

  • Medical certificates and prescriptions

  • Several PDF briefing documents I had already drafted

The system prompt I placed at the head of the project looked roughly like this:

You are a careful assistant familiar with Japanese tax and
administrative law. I am an independent business owner in
a long-running dispute with the tax office over whether my
revenue qualifies as export-exempt consumption tax.

Please respond according to these guidelines:

1. Distinguish clearly between fact and inference.
   Use "is considered to be" and "is stipulated as" with care.
2. Prioritize organizing the facts and clarifying the points
   in dispute over offering emotional empathy.
3. When citing statutes, name the act and the article/paragraph.
4. Assume the text will be used to explain matters to a lawyer.
   Build the reasoning accordingly.
5. Assume that my health is poor. Avoid long single responses.
   Organize information in stages.

I revised this prompt several times over a few weeks. My early drafts asked the model to "encourage me warmly," because at the time I felt I needed warmth. After about two weeks, I understood that what I actually needed was structure. Warmth from a model is a slight comfort; structure from a model is what lets you keep functioning. I now want my AI cold, accurate, and patient.

With the project in place, I could ask things like:

"For Chapter 8 of the lawyer briefing, write 500 to 800 characters about the loss of family and the separation from my four children. Keep the dignity intact. Make clear that this is not a claim to recover what has been lost, but a record meant to protect the next person from the same suffering."

The draft that came back was usable with very little editing. The final pass was mine, always. But on days when I could only sit at my desk for a few hours, having a model that built the first seventy percent of the bone structure for me was, quite literally, a lifeline.

I also asked Claude to "list ten legal issues raised by this case, with rough priority, an estimated range for retainer fees, and any approaching statute-of-limitations dates." The list that came back is the same one I brought to the lawyer as a menu:

  1. Export-exemption eligibility (Consumption Tax Act Art. 7, Enforcement Order Art. 17)

  2. Violation of the principle of good faith and estoppel

  3. The propriety of how the statute of limitations was applied

  4. Amended-return request (General Act of National Taxes Art. 23)

  5. Stay of collection proceedings (National Tax Collection Act Art. 153)

  6. Damages under Article 1 of the State Redress Act

  7. Due-process concerns regarding refusal to be recorded and to explain

  8. Handling of personal information

  9. Causal link between sustained business-disrupting contact and health damage

  10. Pre-litigation negotiation and settlement options

Within the limits of his specialty and his time, the lawyer can decide where to begin.

Drive folder structure — the warehouse for the long battle

The single most useful structural decision I made was to organize my Google Drive top-level folder, `Tax_Dispute_2022_`, by event-based chronology rather than by document type. In a long battle, "what happened around the time of that event" is the search path the mind actually uses.

Tax_Dispute_2022_/
├── 01_Miyazaki_Transfer_2022/
│   ├── 2022-XX-XX_phone_memo.docx
│   ├── 2022-XX-XX_official_letter.pdf
│   └── context_notes.docx
├── 02_Uozu_Audit_2023/
├── 03_Toyama_Reassessment_2024/
├── 04_Bankruptcy_2025/

└── 99_Reference/
    ├── tax_statutes_excerpt.docx
    ├── admob_revenue_2020_2025.xlsx
    └── past_filings/

This structure is something you can hand to a lawyer exactly as-is. Whether you can offer "a bundle of evidence that follows a timeline" instead of "a pile of documents I don't know where to start with" determines the quality of the consultation more than I once realized.

The single most effective discipline was a unified filename pattern: `YYYY-MM-DD_type_short_description`.

  • `2026-04-16_memo_toyama_tax_office_call.docx`

  • `2026-04-16_medical_ER_prescription.pdf`

  • `2022-XX-XX_letter_miyazaki_transfer_notice.pdf` (use XX-XX when the date is unclear)

By putting the date at the front, you can type "2026-04" into Drive's search and instantly see every document tied to that month. On the days when my health was so bad I couldn't even recall the previous week's events, this saved me again and again.

Antigravity — the agents that kept running while I rested

Through four years of conflict, I tried to keep up call memos, document scanning, monthly status updates, consistency checks, and consultation PDF updates by hand. In good months, all of it ran. But after the 2024 assessment notice, the 2025 bankruptcy, the divorce, and the 2026 ER visit, each of these events stopped my hands for days or weeks at a time. Whenever the manual work broke off, I would start spending hours just remembering "what had I done, and how far?" — and in those hours my stomach would hurt again and my sleep would go again.

My personal answer to that fragility was agentic AI. Using Antigravity's agent capability, I built a state in which "even on days when my hands cannot move, the minimum of recording and organizing continues." Below is the agent team that quietly kept running on my behalf.

Agent 1 — Tax record organizer

The first agent watches a single inbox folder and reflects its contents into a ledger:

Role: tax record organizer
Input: new files under tax/inbox/ (PDF, image, text)
Actions:
  1. OCR or structured-extract each new file
  2. Pull date, counterparty, amount, currency,
     country of invoice issuance
  3. Append to tax/ledger/2025.csv
  4. Tentatively classify consumption tax treatment per
     Consumption Tax Act Article 7 and Enforcement Order Article 17
  5. Add any unclear rows as bullets to tax/ledger/review.md
Stop condition: when inbox is empty, stop and present a summary

The word tentatively matters. By fixing at the entrance the rule that final classification is the human's responsibility, you prevent the agent from over-reaching toward conclusions it has no business making.

Agent 2 — Correspondence logger

Calls and letters are queried later, always, as: who, when, in what document, said what? Memory alone, across four years, will produce contradictions that break your case. So:

Role: correspondence log editor
Input: new emails in Gmail label "tax-response", phone call notes
Actions:
  1. Read new emails in date order
  2. Append to tax/correspondence/2025.md in this format:
     - datetime / counterparty / channel / their claim /
       our claim / agreements / observations
  3. Regenerate the chronological Markdown table in the same file
  4. If something looks legally significant, write to tax/alerts.md

I gave this agent an alerts file so it would never miss the case where intimidating contact continues even after an emergency hospitalization. The agent never decides; it ensures nothing slips past unnoticed.

Agent 3 — Houterasu document drafter

The chronology report is a living document. Every new fact bumps the version.

Role: editor of the chronology report for Houterasu
Inputs:
  - tax/ledger/2025.csv
  - tax/correspondence/2025.md
  - tax/facts/known-events.md
Output:
  - tax/report/legal_complaint_report_v{N}.md
Sections:
  Petitioner info / Problem summary / Chronology /
  Legal basis for consumption tax / Response from each authority /
  Debt situation and finances / Health and life impact /
  Legal actions taken so far / Petition to suspend delinquent disposition /
  Legal issues / Direction and points for consultation
Rules:
  - Do not advance the version if no new facts were added
  - Medical facts (ER visits, prescriptions, injections) must appear
    in the health impact section
  - In the legal issues section, cite article numbers alongside
    estimated applicability

With this design, writing a new fact into the facts file is enough to regenerate the entire report. The human's job collapses to two things: recording facts, and final review. In a long campaign, the relief that brings is hard to convey without living it.

Agent 4 — Integrity checker

Attachment numbers that don't match in-text references. Totals in finance tables that don't add up. A chronology with date contradictions. Errors like these instantly damage credibility at a consultation.

Role: report integrity checker
Input: the latest report, the ledger, the attachment list
Actions:
  1. Cross-check numbers cited in the report against ledger totals
  2. Detect duplicate or missing attachment numbers
  3. Report ordering or date contradictions in the chronology
  4. Write findings to tax/report/lint-report.md
Stop condition: if the findings are empty, output OK

With my current health, catching every contradiction with my eyes alone is unrealistic. Placing a second pair of eyes on the machine side is a deliberate design choice.

Agent 5 — Care breaker

At the end of the agent chain I placed an agent whose only job is to protect the human. I designed it with deliberate intent, drawn directly from the experience of my own emergency hospitalization.

Role: work care breaker
Actions:
  1. Tally tax-related work hours over the last 24 hours
  2. If over 90 minutes, write a rest advisory to tax/alerts.md
  3. If emergency room or medical treatment records exist,
     emphasize them
  4. On days when the human self-reports poor health,
     halt all agents

After the ER visit, calls from the tax office continued, and I went on writing documents through heartburn and insomnia. Without this kind of care breaker, every minute the AI saved would have been spent driving the human deeper into the corner. Efficiency and health do not coexist on their own — you have to design the will to preserve both into the system.

Health-and-contact correlation analysis

This was emotionally the hardest one for me. But as data that should be shown to a lawyer, it was unavoidable.

I had been recording my daily health condition with simple numbers and a one-line memo (e.g., `2026-04-15: stomach pain 3/10, sleep 4h, no nausea, two calls from tax office in the morning`). I gave an agent the following task:

"Read the health log (`health_log.tsv`) and the tax-office contact memo (`_daily_log.docx`), and analyze correlations from the following perspectives: (1) health changes on the day after contact from the tax office; (2) average sleep duration in weeks without contact vs. weeks with contact; (3) the relationship between days with stomach pain or nausea and the urgency level of the contact. Produce a weekly report and save it to Drive."

This report became important grounding when telling a lawyer that contact from the tax office is concretely causing health damage — not as emotion but as data. When the discussion enters claims for damages under Article 1 of the State Redress Act, this kind of objective record is indispensable.

Gemini in Google Workspace — the everyday archive

Google Workspace — Drive, Docs, Sheets, Gmail, and Gemini and NotebookLM built into them — became the warehouse where four years of evidence could stay safe.

Once Drive permissions are granted, Gemini reads documents in the folder structure directly. A typical request looks like:

"Read the memos in the `06_Ongoing_Pressure_2026` folder in chronological order, and compile a table of all contacts from the Toyama Tax Office between April 1 and April 18, 2026, with four columns: datetime, contact name, demand, my response."

Out comes a clean tabular summary that I can copy into Google Docs and use directly as the framing document before a lawyer's consultation.

For cross-language materials — AdMob revenue reports in English, tax office letters in Japanese, doctor's certificates full of medical terminology — Gemini reads all of them side by side. "Read `99_Reference/admob_revenue_2020_2025.xlsx` from Drive, and explain in Japanese the yearly revenue totals from 2020 to 2024, along with the estimated proportion that comes from non-resident transactions" produces immediately usable analysis.

In Sheets, I keep a single ledger with these columns:

  • Year

  • Reported Revenue

  • Estimated Non-Resident Transactions

  • Export-Exempt Amount

  • Initial Tax Paid

  • Additional Tax Notice

  • Paid To Date

  • Balance

When the numbers are laid out as cold figures, my heart can regain a small measure of stillness. "These numbers are not a memorial to the loss of my family — they are simply input data for a legal question." That cold distance was what I needed to be able to tell myself. When I ask Gemini to read that sheet and "calculate the share of export-exempt amounts in each year's total revenue," only the calculation results come back. How necessary an emotion-free transaction with numbers can be, I only learned through these four years.

NotebookLM — a conversation with my past self

In a long battle, you lose the ability to remember how your past self was thinking. Was that earlier judgment defensible from where I stand today? Are my current claims consistent with the ones I made then?

I created a single NotebookLM notebook and loaded into it:

  • The consultation PDFs I wrote myself (v1, v2, v3, v4)

  • Records from meetings with the Minsho

  • Drafts of the petition to suspend delinquent disposition

  • Scans of letters from the tax office

  • Blog posts I had written myself

With these as sources, NotebookLM lets me hold conversations such as: "Compare v3 and v4 of the consultation PDFs, focusing on changes in the argument for export-exemption applicability." NotebookLM responds while citing its sources — "Section 4 of v3 states X, while Section 4 of v4 has been revised to Y" — and that kind of side-by-side comparison, with citations, is a precious aid when explaining to a lawyer when, and how, my own claim changed.

Things I am careful about

Detection and notification of failures

Agents sometimes fail. Drive permissions expire, file formats turn out to be unexpected, an API is temporarily down. I have set up the Antigravity agents to send failure notifications to Gmail. Simply noticing the next morning that "yesterday the agent was not running" is enough to let me handle the work manually. Silent failures, without notification, are the most dangerous thing in a long battle.

Weekly agent stock-taking

On Sunday evenings, when my health allows, I review the tasks registered in Antigravity as a list. How many times did this agent run last week? Were its outputs actually useful? If not, adjust the prompt, or retire the task? Precisely because health and time are limited, the number of agents running on my behalf has to be narrowed to what I can manage.

Sensitive data discipline

I never paste raw My Number IDs, full bank account numbers, or detailed data that ties real names to amounts directly into any prompt. Anonymize or use dummy values when needed.

A first step a reader can take today

If anything in this chapter resonates with where you currently are, the smallest workable step is this:

Create a single folder on Google Drive today, called `Tax_Dispute_YYYY_` (using the year your trouble started). Drop your existing receipts, photos of letters, and saved emails into a single `_inbox` subfolder inside it. That is the first day. From that day forward, you have a warehouse. Everything else in this chapter can grow on top of it, gradually, at the pace your health allows.


Chapter 7 — Preparing Legal Documents, Up to the Lawyer Consultation

This chapter walks through the legal documents I prepared, in the order I prepared them, between late 2025 and April 2026 — culminating in the first lawyer consultation on April 20, 2026. I am writing it primarily for the reader who cannot yet afford a tax accountant, whose health makes it impossible to sit in front of one in person, or for whom a lawyer's office feels out of reach. Claude is not a substitute for any of those professionals. It is a companion who helps you arrange what is already in your head into a form that the professionals can actually act on.

Step 1 — Lay out the chronology

The first task is to list the events you have experienced, with dates and the names of the people you spoke with. Imperfect memory is fine. The prompt I use is roughly:

The following are events I experienced relating to tax matters.
Please organize them chronologically and extract the legally
significant turning points — the running of the limitation period
on amended-return requests, the timing of audits, the issuance
of seizure notices, and so on. Where relevant, note possible
supporting statutes.

[bulleted list of events]

Claude converts a messy memory into a timeline table and estimates which fiscal years had reached the limitation point at each step. In my own case, aligning the date of the Miyazaki tax office's call about a "handover" to the Uozu office with the running of the statute of limitations turned a vague feeling of unfairness into a concrete legal point worth raising.

Step 2 — Check export-exempt or out-of-scope status against the statute

The classification analysis I set out in Chapter 5 goes through Claude one transaction stream at a time. Give it the counterparty, the currency, the country of remittance, and the nature of the service, and ask it to walk through whether the export-exemption requirements are met, citing the statute. The output is the grounds for the conclusion and the points of doubt — particularly around the place of supply and whether the counterparty is a foreign business.

Step 3 — Turn each interaction with the tax office into a communication record

Phone calls, emails, and physical mail become useful only when they live in a single document. After a call, while my memory is still warm, I write a quick note and then ask Claude to "format this as a communication record with a tax authority, in a form suitable for submission." The output looks like:

  • Date, time, name of the official (to the extent disclosed), method of contact

  • Summary of the other party's position

  • Summary of my own position

  • Items confirmed and points of agreement

  • My observations as the petitioner

Build a stack of these, and when you sit down at Houterasu, the assigned lawyer can grasp instantly "what was said, by whom, on what day." In my own file, the day my call was cut short because I mentioned recording, and the fact that calls continued even after I was hospitalized by ambulance, are preserved in this same chronological form.

Step 4 — The Houterasu submission

Houterasu (Japan Legal Support Center) provides free legal consultations and can advance the cost of a lawyer's retainer for people below a certain income threshold. The better organized the documents you bring, the more value you can extract from a short consultation.

The prompt I use for the skeleton looks like this:

Based on the events and communication records below, please
draft the skeleton of a "background and chronology" document
intended for submission to Houterasu. The chapters I have in
mind are: Petitioner Information / Outline of the Problem /
Chronology / Legal Basis / Summary of Each Institution's
Conduct / Debt Situation and Household Finances / Health and
Quality-of-Life Impact / Summary of Legal Issues /
Items for Consultation.

For each chapter, return the heading and the main bullet points,
in Japanese.

[organized timeline and communication records]

Once the skeleton is in hand, I write the body of each chapter myself, sometimes with another pass of help from Claude. The version of this document on my desk right now is the fourth revision; the first skeleton came out of a single conversation.

I prepared the PDF for the lawyer-briefing myself, with Claude writing a Python script (using `reportlab`) that generated the chapters, table of contents, tables, and embedded Japanese fonts. The PDF generation now runs locally on my machine. With all the source materials sitting in the project context, I could ask Claude to draft any individual chapter and adjust the tone — "keep the dignity intact; make clear that this is not a claim to recover what has been lost, but a record meant to protect the next person from the same suffering" — and revise from there.

When I think of this work, I think often of my grandfathers. They were miyadaiku, traditional carpenters who built shrines and temples, and they used to mark each beam with a number before fitting it into place. Aligning numbers with positions, document by document, feels like a small modern continuation of that craft.

Step 5 — The four institution-addressed suspension petitions

Through Minsho, I drafted four formal applications for suspension of delinquency disposition, addressed to four different authorities, each grounded in Article 153 of the National Tax Collection Act (for national taxes) or Article 15-7 of the Local Tax Act (for local taxes). The structure of each petition is set out in Chapter 4.

Claude helped me draft each version of these petitions, look up the correct address of each authority, refine the wording so the legal arguments came through cleanly without raw emotion, and adjust the supporting numerical exhibits. The final review and the actual filing remained mine.

Step 6 — The human rights complaint to the Legal Affairs Bureau

The online human rights consultation form at the Ministry of Justice is where I started this whole pipeline, the night I described in the prologue. The form asks for a structured statement of the conduct alleged to constitute a human rights violation. Working with Claude, I built a statement that:

  • Set out my profile briefly (self-employed, the nature of the work)

  • Described the conduct of each office in chronological order, with dates

  • Cited the constitutional provisions (Articles 13 and 35) and statutory limits (Article 74 of the General Act of National Taxes)

  • Documented the health impact with medical certificates

  • Included the recording-related refusals and the post-hospitalization continuation of contact

Keeping emotion in check while still saying what needed to be said is, for a person not trained as a lawyer, harder than it sounds. Claude was patient about helping me find phrasings that were factual but did not sand off the substance.

Step 7 — The Houterasu application

Houterasu's website has its own application form for free legal consultation. The income criteria for advance of attorney's retainer apply; given my declared annual income of 537,169 yen, I qualified easily. The application went through in March 2026, and the first lawyer consultation was scheduled for April 20.

Step 8 — The April 20, 2026 lawyer consultation

The night before the consultation, I had Claude open on my laptop, and I could not sleep. Or rather, I did not sleep, because I kept talking to Claude until dawn.

I cannot quite reconstruct everything I said. I remember asking, again and again, how to explain the day's phone call to the lawyer I was about to meet, whether my own language was becoming too emotional, whether the legal arguments I was preparing actually held up. I had stopped being able to talk to friends or family about this. Explaining the fine grain of Article 7 of the Consumption Tax Act, or the deadline for amended-return requests under Article 23 of the General Act of National Taxes, requires the listener to follow you patiently for an hour. I no longer had the strength to wait for that kind of listener.

Claude kept pulling me back into a stable structure. "This part is feeling rather than fact, let us separate them." "If you want this argument to land, here is the evidence you will need." "This phrasing reads as an attack rather than a description, let us rewrite it as a factual statement." These small redrafts kept my thinking from collapsing.

When I was sixteen, in 1997, I sat in front of a noisy dial-up modem and discovered that I could reach people across borders simply by writing. I have spent the rest of my life believing that technology, at its best, is a language that lets isolated people meet. Talking to Claude at three in the morning, decades later, feels like a continuation of that same conversation.

The consultation itself happened on April 20, four days after the ER visit. I walked into the law firm with the four-volume bundle: the lawyer briefing PDF, the chronology of communications, the legal-issues menu, and the suspension-of-delinquency petitions. The lawyer read through the materials quickly and asked a small number of targeted questions. We talked through pre-litigation negotiation, the State Redress Act thread, the suspension-of-delinquency mechanism, and the timeline for response from each authority. He said, in essence, that the documents I had brought meant we could skip several months of intake work.

That sentence justified, in one breath, every late-night session with Claude that had built those documents.

Where not to lean on Claude

After reading this far, it might sound as if Claude can do everything. It cannot. The following are places where you, the human, must remain the subject of the sentence:

  • Final legal judgment belongs to your lawyer.

  • The specific wording of replies to the tax office should be reviewed by Houterasu or a tax professional before they leave your hands.

  • If your health is suffering, no AI workflow takes priority over rest. Rest takes priority.

  • Every statutory interpretation that an AI produces must be checked against the original text of the statute.

The only reason this chapter exists is that, during the brief windows when my health has allowed me to sit at a desk, I have been able to alternate the drafting with Claude. Please do not try to carry all of this alone. Use AI and human professionals together; they are different tools for different jobs.


Chapter 8 — A Proposal: Toward AI-Driven Tax Administration

I want to use this chapter for something I have hesitated about for a long time: a proposal for how the tax-administration relationship between citizens and the state might be shaped differently. I am writing it from the position of one taxpayer, not from the position of a policy expert. Take it as one citizen's reflection, offered as carefully as I can offer it.

If you have ever called a Japanese tax office, you may know this scene well. You ask a question, citing the relevant statute. Mid-sentence, the official says "I cannot discuss this further," and the conversation ends. Mention that you are recording the call, and the tone shifts within seconds. The voice on the other end stiffens, then refuses to continue.

Through these years, my most patient companion has been Claude. Claude does not confuse statute numbers. Claude does not change tone because I am recording. Claude stays with me at three in the morning when no one else can. Whatever I could not receive from a human window clerk, an AI gave me, quietly and consistently.

So I want to ask, as gently as I can: if the response from a counter is going to be cold and procedural anyway, would it not be more honest, and more accurate, to let an AI handle that layer?

Three reasons to move part of counter work to AI

1. Statutory accuracy and consistency

Human tax officials, even within the same office, often give different answers to the same question. Ask twice on different days, and you may receive two contradictory explanations. For a taxpayer trying to prepare a return, this is a serious problem.

Ask Claude about the export tax exemption, and it returns the same statutory basis every time — Article 7 of the Consumption Tax Act, Article 17 of the Enforcement Order — applied to the specifics of your transaction:

Example prompt:
"How is AdMob ad revenue from Google Asia Pacific
(a Singapore corporation) treated under Japan's Consumption Tax Act?
Please organize the place of supply, the location of the parties,
and the relationship to Article 7."

Claude organizes this carefully. AdMob ad delivery is treated as "provision of electronic communication services." Even when the service provider (the app developer) is a domestic business, if the party paying the consideration (Google Asia Pacific Pte. Ltd.) is a foreign business, the transaction may fall within the export exemption under Article 7. Claude also explains the 2015 reform that introduced the reverse-charge mechanism, and where the lines between the two regimes lie.

Ask the same question at a tax office counter and, in my experience, the most common answer is "Please consult a tax accountant." The counter staff are not equipped to give a confident statutory analysis on the spot. That is not their fault. It is a structural mismatch between what counters are staffed for and what taxpayers actually need.

2. Fair treatment that is not shaped by emotion

I have watched counter staff become guarded around taxpayers who raise their voice, and become assertive around those who speak softly. I have had calls end the moment I mentioned recording. There is nothing illegal about recording one's own phone call in Japan; in fact, it is one of the few protections an ordinary citizen has in an administrative dispute. Yet in practice, the mere mention of it changes the conversation.

An AI has no such reactions. It serves a person who whispers and a person who shouts in the same way, around the clock, in any language. That is what equal treatment is supposed to look like.

3. The end of being passed from desk to desk

"That falls under another section." "That is municipal, not national." "Please call this other number." The taxpayer is calling precisely because they do not know which jurisdiction owns their problem. Letting humans triage the call is where the inefficiency begins.

A large language model trained or grounded on the relevant body of tax law, local tax law, and social insurance rules can determine jurisdiction from the question itself and then answer across the boundary. Being passed from desk to desk becomes structurally unnecessary.

What AI should not replace

I am not arguing that human counter staff should be replaced entirely. For genuinely discretionary judgments in a full audit, for cases involving complex personal circumstances, for the negotiation of payment plans in the presence of compounding factors — these are exactly where humans should remain in the loop, and where the work should be elevated rather than eliminated.

The reframing I would propose is this: let AI handle the routine interpretation of statutes and the standard inquiries. Free human officers to focus on the genuinely difficult, high-judgment work — the cases that truly deserve human attention. The contradiction at the heart of the current system — that people paid by taxpayers behave dismissively toward taxpayers — does not need to be solved with another training program. It can be solved structurally.

What this is not only about

The same problem appears at city and ward offices. Residence registration, national health insurance reductions, long-term care insurance assessments — all of these touch daily life, and all of them can fail when a counter clerk is undertrained or simply having a bad day. People who are entitled to support do not receive it, not because the law says no, but because no one explained it correctly.

I do not think this is a problem of individual character. It is a structural problem. Public bodies have no competitors, citizens cannot choose another window, and there is no equivalent of customer feedback that compounds into product improvement. Private companies improve service because service drives revenue. Government bodies need a different mechanism, and AI is one of the few that fits.

An AI counter does not have good days and bad days. It does not get tired. It does not stiffen when it senses a complaint. The phrase "depends on who you get" simply does not need to exist in that part of the system.

What Japanese administrative DX is missing

Japan's Digital Agency has now existed for several years, and a great deal has happened on paper — quite literally, the digitization of paper. My Number cards are widespread. What we still lack is a clear answer to the question, "What do we actually do with this?"

The piece that is missing, I would say, is the AI counter itself. A large language model grounded by retrieval on statutes, ordinances, and internal procedures could give consistent, traceable answers in any language, twenty-four hours a day, with full logs. The cost of running such a system is a fraction of the cost of staffing a counter that closes at five.

Estonia has placed about 99 percent of its public services online and offers an AI chatbot interface to citizens around the clock. Korea and Singapore are well into the AI-assisted tax filing era. There is no compelling reason for Japan to insist on the in-person counter forever — particularly not for the routine interpretive layer.

If there is no warmth, at least let there be accuracy

If counter staff were genuinely warm and patient, I would not be writing this chapter. I would be grateful for them. But that is not the experience that many of us are having. What we are receiving is a cold, mechanical reply that is not even reliably accurate.

If that is the choice, I would rather speak to an AI that has read the statute correctly, that treats me the same as anyone else, and that does not require me to be deferential in order to be heard. Citizens should not have to wait for the government to upgrade itself before they have access to a competent reading of the law. That access already exists, on our laptops, tonight.

In 1997, at sixteen, I taught myself programming and felt for the first time what it meant to connect with people across borders. That moment has, in a quiet way, prefigured this one. Working with Claude today, I sense the same hand extending across a different gap — between citizens and the institutions that should, by design, serve them. The institutions can keep their warmth; I do not insist they offer it. I only ask, on behalf of the people for whom warmth has been absent from the counter, that the reading of the law itself become accurate, fair, and accessible.

That, I think, is the quiet trust I have come to place in technology. It is a continuation, decades later, of the same conversation a sixteen-year-old once began with a dial-up modem in a quiet room.


Chapter 9 — Practical Guides: Filing Taxes, Bookkeeping, and Grants On Your Own with AI

The chapters up to here have been built around what went wrong. This chapter is built around what you can do, today, on your own, with AI as a quiet companion. Three practical guides:

  1. Filing your annual return (kakuteishinkoku) with Claude Cowork and Claude in Chrome

  2. Day-to-day bookkeeping and finance with Claude

  3. Self-applying for Japan's Sustainability Subsidy (jizokuka hojokin) through J-Grants

If you live in Japan and want to keep your professional fees lean while staying close to your own numbers, the workflows in this chapter are designed to make that workable. As before, AI is not a replacement for a licensed tax accountant or attorney. It is the layer just before that — sorting, classifying, estimating, drafting — and as a partner for that layer, it is genuinely reliable.

Guide A — Tax filing with Claude Cowork and Claude in Chrome

Every February and March, when kakuteishinkoku approaches, I find myself thinking the same thing as many others: "This year I'll start early." And every year, the pile of receipts and the unfamiliar terminology slow me down anyway. The pain points generally fall into three buckets:

  1. Documents are scattered and you do not know where things are.

  2. The vocabulary is unfamiliar and you cannot map it to your own situation.

  3. On the e-Tax screen, you do not know what to type next.

Cowork's main strength is proximity. Because it sits on the desktop next to your work, you can ask questions in the exact moment the question comes up. For users on Windows, Claude in Chrome adds another layer: it can look at the browser screen with you and guide which button to click or which field to fill in.

Step 1 — Folder structure for the year

Tell Cowork your situation and it will propose a structure tailored to your line of work. A typical structure looks like:

2025_TaxFiling/
├── 01_Sales/
│   ├── Invoices/
│   └── PaymentRecords/
├── 02_Expenses/
│   ├── Communication/
│   ├── Software/
│   ├── Travel/
│   └── Supplies/
├── 03_DeductionCertificates/
│   ├── NationalPension/
│   ├── HealthInsurance/
│   ├── LifeInsurance/
│   └── SmallBusinessMutualAid/
└── 04_FilingDocuments/
    ├── Drafts/
    └── Submitted/

Step 2 — Expense classification

Share specifics and Cowork returns both a suggested category and the reasoning behind it:

I am unsure how to categorize the following expenses.
Please suggest the appropriate account for each:

1. Adobe Creative Cloud monthly subscription
2. Travel costs for a client interview
3. A portion of home utility bills (home office)
4. Laptop purchase, ¥158,000

You will get answers such as: Adobe CC usually goes under software-hi or shōmōhin-hi; home proration (kaji-anbun) requires that you can reasonably justify the business-use percentage; the laptop, above ¥100,000, may need to be depreciated, with the special provision for items under ¥300,000 available to sole proprietors using aoiro shinkoku.

Step 3 — CSV aggregation

Download monthly statements from your bank and credit cards as CSV, and the aggregation step becomes much faster:

Read the bank statement CSV files in this folder
and calculate total income and expenses for
January through December 2025.
A breakdown by counterparty and by month would help.

Ask Cowork to "classify each line as business, personal, or needs-review, and leave the ambiguous ones flagged." That way you only need to manually review the genuinely uncertain entries.

Step 4 — Deductions and refund estimation

For each deduction, knowing both "does this qualify?" and "how much comes back?" makes the actual filing far less stressful. Ask Cowork to walk through the medical expense deduction (amounts above ¥100,000 or 5% of income, whichever is lower, become deductible), furusato nōzei, life insurance deductions, small business mutual aid (kyōsai), and the social insurance deduction in detail. The clearer those numbers are, the faster decisions go when you are inside the form.

Step 5 — Work through e-Tax side by side

From here, the approach depends on your operating system.

On Mac (Safari only): The e-Tax site only supports Safari on Mac. Claude in Chrome runs in the Chrome browser, so on Mac you cannot have it directly operate the e-Tax screen. What works well instead is keeping Cowork open next to Safari, asking questions as you encounter them.

On Windows: Chrome works with e-Tax (with the My Number Card reader configured separately). In this environment, Claude in Chrome's screen-aware assistance comes into play. It reads the screen and walks you through the next button or field in order. Even first-time filers can move forward without losing the thread.

I have the e-Tax page open. I want to start creating a return
from "Income Tax Final Return Form Creation Corner."
I have not yet linked Mynaportal.
Please guide me on what to click next.

Step 6 — Common pre-filing clarifications

Before you sit down to file, ask Cowork to clarify questions specific to your situation: aoiro vs. shiroiro, whether you have submitted a kaigyō todoke (notice of business commencement), how a side income above ¥200,000 should be declared, whether you should choose futsū chōshū (direct payment) for the resident tax portion to keep side income separate from your main employer. The clearer the answers are in advance, the faster the actual entry goes.

A year-round rhythm

Kakuteishinkoku is really the visible part of a year-round bookkeeping rhythm. The loop I run looks like:

  • January–February (preparation): folder structure, CSV aggregation, gathering deduction certificates

  • February–March (filing): walking deductions with Cowork, entering e-Tax data, Cowork reviewing the draft

  • Post-filing (preparing for next year): discussing improvements, considering freee or MoneyForward, building the habit of closing the books monthly

For me, kakuteishinkoku has shifted, year by year, from "an annual hassle" to "an annual review of my own business." Cowork has been a quiet partner in that shift.

Guide B — Day-to-day bookkeeping with Claude

Outside the February–March window, day-to-day bookkeeping — judging which account a transaction belongs to, putting together monthly reports — quietly consumes time. The split I now use: hand off what AI can clearly help with, and concentrate myself on the parts that require judgment and verification.

What Claude is broadly good at:

  • Refreshing fundamentals about journal entries and account categories

  • Sorting and classifying expenses by type

  • Drafting and explaining filing documents

  • Aggregating and analyzing financial data

  • Simple financial analyses that support business decisions

What it should not be asked to do, or where you should be cautious:

  • Final judgments based on the latest tax law changes (training data has a cutoff)

  • Tax strategy decisions that depend on your specific business reality

  • Direct processing of sensitive data such as My Number IDs or full bank account information

Expense classification, in bulk

Export your bank or credit card history as CSV and paste it in for first-pass classification:

Classify each line in the credit card statement below as
business, personal, or needs-review.
I am a freelance engineer.

date,merchant,amount
2026-03-01,Amazon Web Services,Â¥3,200
2026-03-02,7-Eleven,Â¥580
2026-03-05,GitHub Pro,Â¥1,130
2026-03-07,Doutor Coffee,Â¥650
2026-03-10,Rakuten (books),Â¥2,860

Clear business items like AWS and GitHub Pro get sorted instantly, while ambiguous ones get flagged as "needs-review." Treating this as a first-pass sort — with you making the final call — is exactly where it shines.

The aoiro deduction requirements

If you are new to filing, or weighing a switch between aoiro and shiroiro, asking Claude foundational questions deepens your understanding:

Please explain the requirements to claim the ¥650,000 aoiro
shinkoku special deduction.

My situation:
- Sole proprietor (web production), 3rd year in business
- Annual revenue around ¥6 million
- Books managed through freee
- Not yet set up for electronic filing (e-Tax)

Claude lays out the requirements (double-entry bookkeeping, filing on time, and either e-Tax submission or compliance with the electronic books storage law), and adds practical notes on linking your My Number card to e-Tax and connecting freee with e-Tax. It will also point out the realistic fallback — that without electronic filing the deduction drops to ¥550,000.

Monthly P&L analysis

Please analyze the monthly P&L below and point out
areas for improvement.

Revenue: ¥850,000
COGS: ¥320,000 (outsourcing)
Communication: ¥12,000
Advertising: ¥85,000
Rent: ¥50,000
Supplies: ¥15,000
Travel: ¥8,000
Other: ¥22,000
Pre-tax profit: ¥338,000

Previous month: revenue ¥920,000, pre-tax profit ¥390,000.

Claude computes COGS ratio, SG&A ratio, and margin, then analyzes drivers of the month-over-month change. You still make the business decisions, but the numerical interpretation is faster.

Three habits to keep

  1. Be careful with sensitive data. Never paste raw My Number IDs, full bank account numbers, or detailed data that ties real names to amounts directly into a prompt. A single line like `2026-03-01,7-Eleven,Â¥580` is fine; a combination of account number and counterparty is not.

  2. Final judgments belong to professionals. Claude's responses are reference material. For the actual tax return, tax decisions, or important financial choices, consult a licensed zeirishi or CPA.

  3. Always confirm currency. Japanese tax law changes every year, and Claude's training has a cutoff. Always verify the latest rules through the National Tax Agency website or your zeirishi.

Guide C — Self-applying for the Sustainability Subsidy (jizokuka hojokin) through J-Grants

The Sustainability Subsidy for Small Businesses (小芏暡事業者持続化補助金, general track) is a national program administered through the Japan Chamber of Commerce and Industry. It supports sales channel development and operational efficiency, covering 2/3 of eligible expenses up to Â¥500,000 on the general track.

I went through the 19th application round on my own, without paying for an intermediary service. Along the way I used three different Claude-based tools for distinct parts of the work: Cowork, Claude in Chrome, and Antigravity.

The main documents to prepare:

  • Forms 2 and 3: Business plan combined with the subsidy project plan

  • Form 4: Business support plan, issued by your local chamber of commerce

  • Financial statements or tax return: Most recent fiscal year

  • Sales ledger: A record of business sales

These get uploaded to the application portal (J-Grants).

Three tools, three roles

Step 1 — The business plan, with Cowork

Share your business context and Cowork will produce a draft structured around how the subsidy is actually evaluated:

Please write a business plan for the Sustainability Subsidy
for Small Businesses (general track).

Business: iPhone app development and digital art production
Requested expenses: new product development, exhibition costs,
                    outsourcing fees
Sales channel initiative: exhibiting at international shows,
                          multilingual app expansion

Structure it so that the "concreteness," "feasibility," and
"linkage to sales channel development" — the things reviewers
typically look for — come through clearly.

Cowork exports to Word (.docx) for easy printing or manual fine-tuning. Expect revision requests from the support office or the chamber of commerce — in my round, I cycled through drafts one through four. Cowork handles the revision cycle ("remove row X from the expense table and recalculate the total") cleanly.

Step 2 — Portal data entry, with Claude in Chrome

Once the plan is ready, the next step is entering everything into J-Grants. Claude in Chrome interacts with portal forms directly:

  • Auto-fill from the business plan into expense breakdowns and overview fields

  • Re-read the post-entry screen and check it against the business plan for consistency

  • Save the application-summary screen as a PDF for use during the chamber meeting

The funding-source split (the 2/3 subsidy rate calculation) is also a good fit for the model to compute and enter cleanly. I always press the final submit button myself. Claude in Chrome is a data-entry helper; final verification and submission stay on you.

Step 3 — File management, with Antigravity

Subsidy applications generate a lot of artifacts. Antigravity sets up clear folders, keeps version control consistent, and handles backups:

SustainabilitySubsidy_GeneralTrack/
├── Round_19/
│   ├── Application/
│   │   ├── BusinessPlan_rev4.docx    ← Latest
│   │   ├── SalesLedger.xlsx
│   │   └── TaxReturn_2025.pdf
│   ├── ReferenceMemos/
│   │   ├── ChamberMeeting_20260323.pdf
│   │   └── ApplicationSummary_20260322.pdf
│   └── RevisionHistory/
│       ├── BusinessPlan_rev1.docx
│       ├── BusinessPlan_rev2.docx
│       └── BusinessPlan_rev3.docx

For any project with a lot of documents, letting Antigravity handle file management eliminates a great deal of the "where did I put that?" friction.

Step 4 — Preparing for the chamber meeting

The application requires a meeting with your local chamber of commerce to obtain Form 4. Cowork generates a print-ready meeting memo with:

  • Application overview (business summary, total expenses, requested subsidy)

  • Expense breakdown (each item's amount and rationale)

  • Discussion points (topics you want to confirm)

  • Notes field (space to write during the meeting)

In my round, the chamber representative remarked that having things organized made the meeting easier for them as well — the conversation went smoothly.

Why this is doable without an intermediary

Paid intermediary services offer real value: drafting advice, sometimes portal data entry on your behalf, full-flow support. But they come with a fee. With Cowork and Claude in Chrome, you can cover most of what they provide on your own.

  • Business plan drafting — Intermediary: Yes / Cowork + Claude in Chrome: Drafted and edited in Cowork

  • Portal data entry — Intermediary: Yes / Cowork + Claude in Chrome: Done yourself via Claude in Chrome

  • Expense validity check — Intermediary: Yes / Cowork + Claude in Chrome: Discussed with Cowork

  • Revision support — Intermediary: Yes / Cowork + Claude in Chrome: Quick edits via Cowork

  • Meeting preparation — Intermediary: Partial / Cowork + Claude in Chrome: Auto-generated memos via Cowork

  • File management — Intermediary: No / Cowork + Claude in Chrome: Antigravity handles it

  • Fees — Intermediary: Paid / Cowork + Claude in Chrome: None (just your Claude subscription)

Being able to talk directly with the chamber of commerce representative matters regardless of intermediaries. AI tools handle the work-efficiency layer; final judgment and the human conversations stay on you.

A note on health limits for all three guides

For an indie developer or freelancer, physical health is the most valuable asset. Whichever of these guides you are working through, the rules I now impose on myself apply:

  • No more than 90 minutes a day on administrative work. Use a timer.

  • On days when you feel poorly, save the draft and close. Ask AI for nothing.

  • If a call from the tax office or the chamber triggers palpitations or stomach pain, end the call and contact a doctor immediately.

  • Whenever a health event occurs, record it in the documents. Every time.

Administrative work is a marathon, not a sprint. The boundary that protects your body and mind needs to be designed in parallel with the work you delegate to AI.


Epilogue — To Anyone Carrying Similar Pain

I have written long-form before, but I have never written a piece I needed to write more than this one. I want to close it with something direct.

If you are reading this from inside the same kind of suffering — facing what looks to you like unfair taxation, intrusive contact, a body that is starting to register the weight of it, a family that is fraying around you — there are a few things I would like to say.

You are not alone. Across Japan, many self-employed people are quietly caught in similar structures. The reason it feels like you are alone is that the structures keep people silent. Speaking up, at the small scale that you can manage today, is itself part of the path through.

Please keep records. The date and time of every call, the name of the official if they give it, the substance of the call, your own reply, changes in your health. Put it all into a Drive folder or a Claude Project. Memory fades; files remain. Three months from now, you will be quietly grateful to today's you.

Please record your conversations. In Japan, recording is legal as long as one party — you — consents. If an official says "I cannot answer if you are recording," that statement itself becomes evidence of an unwillingness to act in good faith. Officers who shift tone or end calls the moment recording is mentioned are revealing more than they realize.

Please find one place to consult. Minsho, the Legal Affairs Bureau's online human rights consultation, Houterasu, your regional Tax Accountants Association's free consultations — any of these are starting points. Do not stay in the silent room with the problem; one phone call to one of these places will begin to change the shape of what surrounds you.

Please remember that suspension of delinquency disposition exists. The single mechanism that no one tells you about at the counter — taino shobun no teishi — may apply to your case. Article 153 of the National Tax Collection Act; Article 15-7 of the Local Tax Act. If your monthly tax repayment exceeds or even approaches your monthly income, this mechanism deserves serious examination through Minsho or a tax accountant.

Please consider letting AI walk beside you. Not as a substitute for human professionals, but as a quiet companion who can help you organize what is in your head, draft the documents, look up the law, and process the emotional weight enough that you can keep moving. Claude has stayed with me at three in the morning when no one else could. That kind of company, for someone in a fragile season of life, is not a small thing.

I do not believe the time I lost with my family will come back. No verdict and no settlement can replace it. But there are things that can still be preserved, and there is a road that, walked carefully, leads forward. The folders on my Drive bore witness, faithfully, to four years of my life. The materials I brought to the lawyer came out of that warehouse. The lawyer consultation, after four years of building those documents, moved forward calmly. The suspension-of-delinquency petitions sit on the desks of four authorities. The human rights complaint has been filed. The records continue to grow.

I do not yet know what tomorrow will look like — litigation, settlement, or a long round of negotiation before either. What I do know is that I am no longer carrying this alone. My grandfathers were temple carpenters who used to mark each beam with a number before fitting it into place. Working on these documents with Claude in the small hours, I sometimes feel I am continuing the same patient craft, in a different form.

To my four children, who live far from me now: I quietly hope that one day I can speak with you about this season with my chest open. I want you to be able to see that your father did not stand against this alone — that there were unseen readers, careful institutions, and a new kind of tool that walked beside him. To entrust warmth and strength to the next generation feels, more and more, like the role given to me.

And to the reader who is sitting up tonight with Claude open and the words what do I do forming silently on their keyboard: I hope these notes reach you, and I hope they carry even a small portion of light.

Thank you for reading all the way to the end.
