This entry connects your AI client to the official PLATEAU MCP server operated by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT). Project PLATEAU publishes open 3D city models - buildings, roads, urban planning zones, flood risk areas and more - for cities across Japan.

Through the gateway you can search the PLATEAU dataset catalog by city or data type, retrieve CityGML file listings and building attributes for a given area, and obtain 3D Tiles / MVT streaming URLs that can be loaded into map viewers.

Note: the PLATEAU distribution service is operated on a trial basis. Schemas and responses may change without notice, and no service level is guaranteed. Data follows the Japanese government's standard terms of use (commercial use allowed with attribution).
