FAQ

Search for your address using the search box above. Our system cross-references geocoded coordinates and address data from Japan's Geospatial Information Authority (国土地理院) to match street addresses with registered lot numbers. You can also browse by prefecture, city, and postal code.

Navigate to the lot page using the prefecture → city → postal code → lot number directory. Each lot page shows the corresponding street address (住居表示) where available, derived from Japan's official address geocoding data.

Japan uses two parallel address systems. The 住居表示 (jūkyo hyōji) is the postal/street address used for mail and everyday navigation. The 地番 (chiban) is the cadastral lot number tied to land registration and property deeds. They do not share a predictable structure — a conversion table or geocoding is required to translate between them.

Lot code data is sourced from the Ministry of Justice's 登記所備付地図データ (Legal Affairs Bureau cadastral map data), published as open data via the Japanese government's geospatial data portal. Coordinates are matched using the Geospatial Information Authority of Japan (GSI) address search API.

The database currently contains over 5,316,912 registered land parcels across Japan, sourced from the 2025 Ministry of Justice cadastral dataset. Coverage is being expanded across all 47 prefectures.

Yes. A chiban identifies a parcel of land, not a building. If a piece of land was subdivided over time, or if several structures were built on land that was never formally split into separate parcels, more than one building can sit on and share the same lot number. This is one of the reasons jūkyo hyōji was introduced: it assigns each building its own address regardless of how the underlying land is divided.

Use the chiban. Real estate registration documents, sale and purchase contracts, and title records (tōki jikō shōmeisho) all reference the land by its chiban, not its street address. If you only have the street address, you'll need to convert it to a chiban before filing or reviewing registry records — which is exactly what this tool is for.
