About this app
See what homes in Japan ACTUALLY sold for — with official government data. Tochi maps real transaction prices, land values, and disaster risk across all of Japan. No listings, no agents, no guesswork. Just the data you need before a ¥10M+ decision. WHY TOCHI Japan publishes remarkable open data about its real estate market — but only in Japanese. Tochi translates it into English and puts it on a map, so overseas buyers can finally see what locals see. WHAT YOU GET • A map of real transactions. Every dot is a sale that happened, coloured by price per square metre. Tap one for the price, the size, the year it was built, the layout and the zoning. • Ten years of price history for each district, so you can see a direction rather than a snapshot. • Price rankings for the whole country or any of the eight regions, on transaction prices or on official land values. • Flood, storm surge and liquefaction risk, mapped. In Japan this changes from one street to the next, and two neighbouring plots at the same price can carry very different exposure. • Population projections to 2050, and how much of that population will be over 65. An area losing a fifth of its residents is a different proposition from one that is growing, at the same price. • The nearest station, its lines, and how many people use it a day. WHO IT'S FOR Property investors, families relocating to Japan, and akiya hunters who want facts before flying in. FREE TO EXPLORE Browse the nationwide price map and recent transaction data free. Upgrade to Pro for full 10-year history and hazard layers. SUBSCRIPTIONS The free tier shows the transaction map and the most recent year of prices, and carries advertising. Pro adds the full price history, the hazard overlays, area comparison and a saved-areas list. Investor adds PDF reports, an unlimited list and alerts when a saved area's prices move. Both remove the ads. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula Privacy policy:https://jpi-api.japanrealestate.workers.dev/legal/privacy?lang=en
