Overview

AI-generated overview

A hosted MCP server that lets an assistant look up actual Japanese real estate sale prices and official land values from MLIT data by area, year and property.

What you can do
List municipality codes for a prefecture as a lookup step before searching transactions. Search actual closed real estate transactions (land, houses, condos) by prefecture, municipality and year or quarter, returning property type, district, price, floor plan, area, building year, structure and zoning. Retrieve official government land price benchmarks (public land values) for comparison with transaction prices.
When to use it
Useful for real estate investment research, market-rate checks and appraisal work in Japan, or when an assistant needs to answer questions about what properties actually sold for in a given area and period, or compare official land values against transaction prices.
Requirements
A remote streamable HTTP endpoint; no local package, account, API key or header is declared. The README states data is fetched live from the official MLIT real estate information library API and covers transactions back to 2005.
Before you install
The README states a charge of $0.02 per tool call with no subscription or minimum, so usage costs money; check billing before repeated queries. Data is passed to the hosted service and its upstream government API. Prices are historical transaction and benchmark data, not listings or current valuations.

Installation

In SourceWeft

  1. Open Japan Real Estate Prices in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.fujimura-ui%2Fjapan-real-estate-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Japan Real Estate Price MCP — 不動産取引価格検索

Real transaction prices for Japanese real estate — not estimates, actual sales — from the Ministry of Land, Infrastructure, Transport and Tourism (MLIT).

Search actual closed real estate transactions (land, houses, condos) by prefecture, municipality, and year/quarter, plus official land price benchmarks (公示地価).

Tools

list_municipalities

Get municipality codes for a prefecture — the lookup step before searching transactions.

search_transactions

Actual closed-sale prices: property type, district, price, floor plan, area, building year, structure, zoning. This is real market data, not listings or estimates.

get_land_price

Official government land price benchmarks (公示地価) — the stable reference price used for taxation and appraisal, as opposed to volatile transaction prices.

Example queries your agent can now answer

  • "What did condos actually sell for in Shibuya in 2025?"
  • 「渋谷区大山町の土地取引価格の実例を教えて」
  • "Compare official land price vs actual transaction prices in this district"
