Sources and methodology

Source: MLIT Real Estate Information Library property transaction data. We filter the data by category and independently calculate medians and transaction counts.

The median is the central observation when sorted by price (or the mean of the two central observations for even-sized samples). The reference periods differ for market-level figures, transaction history and price trends.

Total transaction prices and published unit prices are summarized separately. Figures are not appraisals of individual properties and may change as the source data is updated.Data update information · Disclaimer for more details.
