「私なら潔く先方の企業の指示に従って宿を出ていきますかね」 ― 法律相談で言われたこと

消費者トラブルで都内の大手法律事務所に法律相談を申し込んだ。弁護士は申込内容を読んでおらず、英語の証拠資料を読めず、不当利得にも内容証明にも触れないまま「勝機は見えない」と受任を断った。その3か月後、私は弁護士会に懲戒請求を行った。

"Personally, I'd Accept It and Leave the Place" — What I Was Told at a Legal Consultation

I applied for a legal consultation at a large Tokyo law firm over a consumer dispute. The lawyer had not read my submission, could not read the English evidence, never mentioned unjust enrichment or a contents-certified letter, and declined the case saying he saw no prospect of winning. Three months later I filed a disciplinary complaint with his bar association.

They Deleted My Account by Automated Email, in the Middle of the Night, While I Was Staying There — One Month with Airbnb and a Minpaku Host

In May 2026, while I was staying at a minpaku on a temporary return to Japan, my Airbnb account was deleted by a single automated email at night. One notice gave two different reasons — a compromised payment method, and activity that could lead to fraud, scams, or abuse — and my appeal was rejected twice with an identical form reply. A record of roughly 25 agents and the month it took to get a full refund.

When the Weak Internalise the Logic of the Strong — A 25-Year Record

A structure I first saw in an elementary-school classroom, and kept seeing in middle school, at work, among neighbours, and in nations. Before beginning an evaluation for complex PTSD, I am setting the facts down. Individuals by initial; schools and organisations by name.

The Saturday I Tried to Rebuild iOS 26 Call Screening from Bulgaria

Rejected by Twilio, geo-blocked by Plivo, saved by Vonage at the last minute — and then I realized the feature I wanted was already in my iPhone's settings. A six-hour detour into VoIP APIs, Japanese-in-Bulgaria friction, and what you actually get when your plan fails.

Field Notes — An AA Battery Run, Narrated by Claude

I needed AA batteries. Before leaving the apartment, I asked Claude where to go. This is what the AI-native life actually looks like — not dramatic, just a soft layer of 'I asked first' over small decisions.
