MLIT Japan Property Prices — Free Data for AI Agents & Real Estate Investors
Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) publishes detailed real estate transaction prices for all 47 prefectures — but accessing this data programmatically has always been clunky.

The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) in Japan has made extensive property transaction price data available for all 47 prefectures. This data, which spans over a decade starting from Q3 2005, includes information such as price, land area, location, building details, and zoning classification. The data is clean and provided in JSON format via an API.
Access to this data is made simple through two options. The first is an Apify actor, which is API-friendly and allows users to query transaction prices directly via the Apify API. The second option involves an MCP server, designed for AI agents like Claude or Cursor, which enables them to query the data using natural language.
This tool is particularly useful for real estate investors, market analysts, AI agents conducting research, and data journalists who can use it to build maps and charts of real estate trends in Japan. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) is Japan's department responsible for land, infrastructure, transport, and tourism. Their Reinfolib system (XIT001 dataset) is the primary source of this property price data, which is the most comprehensive official property price database in Japan.
