How this service works
Pay-per-call land data for any point in Japan from government open data: zoning, hazard zones, land prices, evacuation sites, earthquake records, climate, terrain, ground motion. x402 (USDC on Base), no API key.
Output
Returns a JSON object containing a land_id derived from the coordinates, a modules object with terrain and zoning sub-data (including building coverage ratio, floor area ratio, Japanese zone name, and use area), a status indicator, and a payment receipt with ID and expiry timestamp.
Example use cases
Pre-purchase property due diligence
“I'm considering buying a plot of land near Shibuya at 35.6595° N, 139.7004° E — can you pull the terrain data and tell me the zoning type, building coverage ratio, and floor area ratio for that spot?”
Real estate development feasibility
“I'm evaluating a development site in Osaka at 34.6937° N, 135.5023° E — what does the terrain data say about its zoning classification and maximum allowable floor area ratio?”
Urban planning research for a Japanese neighborhood
“For my research on Tokyo's Minato ward, can you get me the terrain and zoning details for coordinates 35.6581° N, 139.7514° E, including the use area classification and building coverage limits?”

Endpoint
GEThttps://api.chishiru.jp/v1/land/terrain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, government-sourced terrain and zoning data for a specific geographic point in Japan, especially for real estate due diligence, urban planning, or property analysis. It is ideal when no API key setup is desired and micropayment via USDC on Base (x402 protocol) is acceptable. Prefer this over general mapping APIs when you specifically need Japanese regulatory land data such as BCR, FAR, and use area classifications.
Side effects
- Coordinates outside Japan return no data or an error — only Japanese territory is supported
- Invalid or missing latitude/longitude parameters result in a 400 bad request
- Payment failure via x402/USDC on Base blocks the request from being fulfilled
- Coordinates in rural or unmapped areas may return partial or empty module data
- Receipt expiry means the same receipt cannot be reused for subsequent calls
