Why cheap houses in Japan are cheap

The listing usually tells you — in four kanji you can't read. These are the things that turn a bargain into a liability.

再建築不可 — you can't rebuild

If the lot doesn't touch a 4 m road for at least 2 m, you cannot replace the house if it burns or collapses. Common in old towns, almost never explained to foreign buyers.

Hazard maps are Japanese-only

Flood depth, landslide warning zones and tsunami inundation areas are published by the government — in Japanese, tile by tile. We check the exact coordinates of the lot.

Septic tanks, propane, leasehold

浄化槽 maintenance, LPG contracts, 借地権 ground rent and 告知事項 (disclosure matters) change what the house really costs. We translate them into a running-cost view.

How it works

No account, no calls. One listing in, one PDF out.

1

Send the listing

Pay and paste the listing URL (or the listing text plus address if the page blocks robots).

2

We run the checks

Geocode the lot, query the official zoning, hazard, population and transaction datasets, and parse the listing for the risk keywords.

3

Read, then ask

You get a scored PDF with deal-breakers first, cost estimates, and a bilingual question list you can forward to the agent as-is.

Questions

Can foreigners buy an akiya in Japan?

Yes. Japan has no nationality or residency requirement for owning land or houses. Some akiya-bank (municipal) listings attach residency, age or renovation conditions — the report flags those.

Is this legal or real-estate brokerage advice?

No. Akiya Check is an information service. We summarize public government data and the listing text so you can ask better questions. We do not negotiate, mediate, or give legal or tax advice.

Which listing sites do you support?

Any Japanese listing page — SUUMO, AtHome, LIFULL HOME'S, municipal akiya banks, regional agents. If a page cannot be fetched, paste the listing text and the address instead.

Where does the data come from?

Zoning, hazard, population and transaction layers come from MLIT's Real Estate Information Library (不動産情報ライブラリ). Geocoding uses the Geospatial Information Authority of Japan. Listing facts come from the listing text itself. Every report lists the status of each source.

What if the report is wrong?

If we state a fact that turns out to be wrong, we refund the full price. Items the listing does not state are reported as UNKNOWN, never guessed.
