Japan Real Estate Price Map

■ View Real Property Transaction Prices Across Japan on a Map

Wondering how much a property in Japan really sold for?
Planning to buy a home or invest in Japanese real estate?
Researching market trends in a specific Japanese city or neighborhood?

This app shows actual property transaction prices across Japan, plotted as pins on an interactive map. Powered by official open data from the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) of Japan, you can see real sales prices — not government appraisals or estimates.


■ Key Features

▼ Interactive Map View
All property transactions across Japan displayed as pins. Open the map and instantly see real sales prices in any area you're researching.

▼ Filter by Period
Focus on recent transactions only, or look back years to study long-term trends.

▼ Filter by Land Use
Narrow your view by property type — residential land, commercial land, prospective residential land, agricultural land, and more.

▼ Price Trend Graphs
Visualize how prices have moved over time in your area of interest. Spot rising or declining markets at a glance — useful for both buyers and investors.

Each pin reveals transaction date, land use, area, and price.


■ Who Is This App For?

・Overseas investors exploring the Japanese real estate market — identify trending areas before investing
・Foreign residents in Japan considering a home purchase — check actual neighborhood sale prices

・Relocating professionals comparing Japanese cities — compare price levels across regions

■ Why This App?

▼ Real Transaction Prices, Not Estimates
Many "land price" services in Japan show government reference prices (kōji chika). This app is different — we show actual transaction prices reported to MLIT, giving you a more realistic picture of the market.

▼ Nationwide Coverage
Data from across all 47 prefectures of Japan, from major metros like Tokyo and Osaka to rural areas.

▼ Simple and Fast
A clean, minimal interface focused on what matters: the map, the prices, and the trends. The map runs smoothly even with large datasets.

▼ Built on Official Open Data
Powered by Japan's MLIT Real Estate Transaction Information dataset — the same source professional researchers use.

This app uses Real Estate Transaction Information published by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT).

Displayed prices are for reference only and do not constitute an appraisal, valuation, or investment recommendation for any specific property.
