Overview of New Residential Property Prices in Tokyo

In a recent study conducted by At Home Inc., a company known for its real estate information services based in Ota, Tokyo, the trends and dynamics of new residential property prices in the metropolitan area have been analyzed. This information was gathered and released through a partnership with At Home Lab, a sister company based in Chiyoda, Tokyo.

Price Trends and Insights

As of August 2025, the average price of newly built houses in the metropolitan Tokyo area has reached an impressive ¥48.26 million, marking a 0.4% increase from the previous month and representing the first rise in two months. This upward trend is further emphasized by comparing it to the same month last year, indicating a significant 5.9% increase over the last twelve months. Notably, all eight surveyed areas have shown consistent growth for five consecutive months, surpassing year-on-year comparisons.

In particular, four regions including the western wards of Tokyo, Yokohama, Kawasaki, Saitama Prefecture, and parts of western Chiba have set new price records since January 2017, indicating robust demand and limited supply in these key locations.
