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 (encoded as lat_lon_resolution), a modules object with climate data under the 'climate' key (status and data fields), a receipt object with an ID and expiry timestamp, and api_version. The climate module data reflects official Japanese government open data for the queried coordinates.
Example use cases
Real estate due diligence in Tokyo
“I'm evaluating a property in Shinjuku, Tokyo at coordinates 35.6938, 139.7034 — can you pull the climate data for that exact point from Japan's government open data so I understand the local climate conditions?”
Climate risk assessment for construction site
“We're planning a construction project at latitude 34.6937, longitude 135.5023 in Osaka — please fetch the climate data for that site so our engineers can review environmental conditions.”
Academic research on regional climate patterns
“I need to compare climate data for several points across Japan for my research — start with coordinates 43.0642, 141.3469 in Sapporo and give me the government climate data from Chishiru.”

Endpoint
GEThttps://api.chishiru.jp/v1/land/climate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official Japanese government climate data for a precise geographic point in Japan without a subscription or API key — ideal for one-off lookups, agent-driven property analysis, or research pipelines where pay-per-call micro-payment via USDC on Base is preferred over flat-fee plans.
Side effects
- Invalid or out-of-Japan coordinates return an error or empty module data
- Insufficient USDC balance or failed x402 payment results in a 402 Payment Required response
- Coordinates outside Japan's land boundary may return no data or a 404
- Network timeouts on the government data backend may cause delayed or failed responses
- Malformed query parameters (e.g. non-numeric lat/lon) return a 400 Bad Request
