Akiya data studies

Original research from Engawa's government-sourced akiya corpus: natural disaster risk mapped across the catalogue, a municipality subsidy league table, and a listing-freshness audit. Every number is reproducible from our open data, with the method and sources on each page. Free to cite.

Data study We Mapped Natural Disaster Risk for 549 Abandoned Japanese Homes We ran 549 catalogued akiya through official government flood, landslide, tsunami, and earthquake data. Most are safe on paper, but the risk is not priced in the way buyers expect. Data study Which Japanese Towns Pay the Most to Renovate an Akiya We matched 130 renovation and relocation subsidy programmes across 43 Japanese municipalities. Here is the league table of which towns pay the most to fix up an empty home, with amounts and source links. Data study We Checked Which Akiya Listings Are Still Actually for Sale Akiya listings are notorious for going stale. We audited our own catalogue against the source pages and found that 12.2% of homes are no longer straightforwardly for sale. Here are the numbers.
