About Property Research Japan

Property Research Japan (propertyresearch.jp) is an independent site that explains Japan's housing market using the government's own data.

It exists so that anyone buying, selling or renting can check whether an area is expensive, cheap, rising or falling, with numbers rather than a sales pitch.

Independence

• We are not a real estate agent. We do not buy, sell, broker or value property.
• All figures are calculated from public data from Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT), the Statistics Bureau and other public bodies. We never pick or change numbers to favour a property or company.
• Some Japanese pages carry advertising marked "PR" (affiliate links). Advertising never affects the reports or the rankings. See Privacy and advertising.

How the reports are written

Each area report is written from the aggregated data. Every number is checked against the source data, and superlatives such as "highest" or "fastest" are only used after comparing all areas. Sources and methods are on the Data and methodology page.

If you find a mistake, please tell us and we will correct it promptly.
