MLIT Japan Property Prices — Free Data for AI Agents & Real Estate Investors

Description and use

Apify actor and MCP server simplify access to Japanese property price data, enabling automated price tracking, investment screening, and AI research.

Problem

Accessing Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) real‑estate transaction prices programmatically was clunky.

Outcome

The actor and MCP server enable easy, programmatic access to MLIT property price data, facilitating automated price tracking, investment screening, AI research, and data journalism.

Workflow

• Wrap MLIT Reinfolib XIT001 dataset in an Apify actor.
• Expose API endpoint for programmatic queries.
• Create MCP server package exposing get_property_prices tool.
• Install MCP server via npx and add to agent config.
• Query data via API or AI agent tool.
• Use results for price tracking, screening, research, or journalism.

Evidence

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.

Source

The raw data comes from MLIT's Reinfolib system (XIT001 dataset), which I've wrapped in an Apify actor for easy programmatic access.
