Renovating a Tokyo akiya? You’re flying blind on cost.
No transparency.
Tokyo contractors hand you a single number and resist itemizing. You sign your akiya renovation contract without knowing what’s negotiable.
No comparables.
English-language akiya renovation guides give vague "¥10–30M" ranges. Specifics about brand, model, labor, overhead? Nonexistent.
No playbook.
Even fluent Japanese speakers renovating in Tokyo get markups they can’t see — list-price discount theater, padded overhead, scope creep.
I was about to overpay by ¥7,000,000.
In February 2024 I bought a 1980s detached house in Setagaya-ku for ¥39,800,000 — full asking price. Five minutes from Komazawa-Daigaku station. A real Tokyo akiya.
Five months later the renovation quote arrived: ¥23,100,000. It looked professional. It also looked padded — vague line items, a "10% off list" discount on every fixture, ¥2.2M of "general management" overhead. I’d never renovated in Japan. I had no comparables. I almost signed.
Instead I went line-by-line. Four revisions, three months of negotiation, two contractors competing, dozens of items I supplied myself. The signed contract: ¥15,000,000. With change orders during construction, the final paid was ¥15,987,000.
That’s ¥7,113,000 (30.8%) off the original. About $46,000 USD.

“After we moved in, friends and other expats kept asking the same question: "How much did it actually cost?" I’d open the spreadsheet and walk them through it. After the fifth time, I realized — this shouldn’t be a private conversation. So I’m releasing it.”

A NOTE FROM MINSEON
I’m Minseon. I documented every yen so you don’t have to make the same mistakes I almost did. If this saves you even ¥500,000, the investment paid itself back 8×.

Questions
Is this in English or Japanese?
The spreadsheet and playbook are both in English. Japanese construction terms are translated with the original Japanese shown for cross-reference with quotes you receive.
I’m not renovating in Setagaya — is this still useful?
Yes. Pricing in Setagaya is mid-to-upper for Tokyo wards; if anything your numbers will be lower. The categories, negotiation plays, and owner-supply strategies apply to any Japanese renovation (Tokyo, Osaka, Kyoto, anywhere).
How is this different from a free blog post?
Blog posts give you vague ranges. This gives you 200+ line items with brand names, model numbers, unit prices, and what was negotiable. It’s the difference between "houses cost money" and a closing statement.
Can I share this with my contractor?
Yes. It’s licensed for personal use including showing it to your own contractor as a reference. Resale or republishing is not permitted.
I don’t have Excel — does it work in Google Sheets / Numbers?
Yes. The file opens cleanly in Google Sheets, Apple Numbers, and LibreOffice Calc. Some advanced formatting may render slightly differently outside of Excel.
How quickly will I get it?
Instantly. The download link appears immediately after purchase and is also emailed to you.
