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 the land_id (coordinate+resolution key), zoning module data including use area name in Japanese (e.g. 商業地域), building coverage ratio percentage (bcr_pct), floor area ratio percentage (far_pct), urbanization area classification (zone_ja), a status indicator, API version, and a payment receipt with ID and expiry timestamp.
Example use cases
Property due diligence in Tokyo
“I'm looking at buying a plot of land near Shinjuku at coordinates 35.6938, 139.7036 — can you check the zoning, what use area it's in, and what the BCR and FAR limits are?”
Checking development feasibility for a Kyoto site
“We're evaluating a development site in Kyoto at 35.0116° N, 135.7681° E. What's the zoning classification, and what are the building coverage and floor area ratio rules that would apply?”
Real estate research app enriching listings
“For each property listing in our dataset, look up the Japanese zoning data at its lat/lon coordinates — I need the use area name in Japanese, the BCR percentage, and the FAR percentage for 35.1815, 136.9066.”
Technical details
Endpoint
GEThttps://api.chishiru.jp/v1/land/zoning?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, government-sourced zoning classification data for a specific geographic point in Japan — especially BCR, FAR, and use area designations. Prefer it over general real estate APIs when you need Japanese-specific regulatory zoning data (not estimated values) at coordinate level, and when you are already using the x402 micropayment protocol on Base. It is ideal for property due diligence, development feasibility checks, and GIS data enrichment pipelines focused on Japan.
Side effects
- Coordinates outside Japan return no data or an error — the API only covers Japanese territory
- Invalid or malformed lat/lon parameters result in a 400-level error
- Payment failure via x402/USDC on Base will block the request from being fulfilled
- Some rural or undeveloped areas may have no zoning data and return empty or null module results
- Expired or invalid payment receipt causes rejection
