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

Description and use

The solution offers API and MCP tools to access Japanese property price data, simplifying data collection and analysis.

Problem

Accessing Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) real‑estate transaction data programmatically was cumbersome, requiring manual PDF handling and complex web forms.

Outcome

The solution enables automated price tracking, investment screening, AI agent research, and data journalism by providing clean, programmatic access to comprehensive Japanese property price data.

Workflow

• 1. Sign up for a free Apify account (free tier includes 100 GB storage, 100 min/month compute).
• 2. Run the "mlit-japan-property-prices" actor via the web UI or curl API to retrieve recent transactions.
• 3. (Optional) Install the MCP server with npx -y mcpb fetch io.github.atushi1841/[email protected] --transport stdio and add it to your agent config.
• 4. Use the exposed tool get_property_prices to query MLIT data directly from an AI agent in natural language.
• 5. Integrate the API token or MCP server into your analytics, valuation models, or data journalism workflows.

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.

The actor is free to try (pay-per-result pricing at $0.005 per record). No credit card required for the free tier.
