Pre-purchase risk reports for Japan's empty & cheap houses — known in Japan as akiya (空き家)
Paste a Japanese listing URL. Within 24 hours you get an English risk report built from Japan's official zoning, hazard and transaction data — and the exact questions to send the agent.
The listing usually tells you — in four kanji you can't read. These are the things that turn a bargain into a liability.
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.
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.
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.
No account, no calls. One listing in, one PDF out.
Pay and paste the listing URL (or the listing text plus address if the page blocks robots).
Geocode the lot, query the official zoning, hazard, population and transaction datasets, and parse the listing for the risk keywords.
You get a scored PDF with deal-breakers first, cost estimates, and a bilingual question list you can forward to the agent as-is.
Every item is marked OKCAUTIONRISK or UNKNOWN. Unknown means the listing didn't say — and we tell you what to ask.

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.
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.
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.
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.
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.
