DOI 10.5281/zenodo.19625688 →Buy a Japanese house at a court auction without walking into a legal trap.
Japanese court auctions (競売 / keibai) sell foreclosed property well below market. The catch is the fine print: it is all-cash, sold as-is, and a few conditions buried in the court files can stop a foreign buyer outright. Yudane scores every live Fukuoka lot, reads the court documents for you, and gives you one clear verdict before you ever place a bid.

Open the map and browse every lot → The method behind every verdict is published and checkable
A verdict is only worth as much as the method behind it. Yours is open: two peer-reviewed papers, the source code, and the underlying datasets, all released so you can see exactly how a lot earned its risk score before you trust it with your money.
