Rental housing drives a fourth month of growth
The Tokyo Metropolitan Government reported on September 4 that 10,939 new homes were started in July 2026, up 6.6% from a year earlier and the fourth consecutive annual increase. Owner-occupied housing rose 9.8% to 1,147 units and rental housing climbed 10.4% to 6,820 units. Housing built for sale, however, slipped 0.9% to 2,944 units. The figures show that Tokyo's overall supply recovery is being driven largely by rental construction. Strong employment concentration and household inflows continue to support rental demand, although project economics vary significantly by location as land and construction costs remain elevated.
Condominium starts fall while detached homes increase
Within housing built for sale, condominium starts dropped 15.0% year on year to 1,376 units, while detached homes increased 19.3% to 1,563 units. High land acquisition and construction costs have made new condominium projects increasingly expensive, especially in central Tokyo. If condominium starts remain subdued, tighter new-build supply could continue to influence resale pricing and buyer demand. The sharp increase in detached housing may also reflect consumers looking for alternatives to increasingly expensive condominiums in some parts of the metropolitan area.
Investors should separate rental supply from ownership supply
For overseas buyers, the latest figures demonstrate why Tokyo cannot be treated as a single housing market. Rental construction is expanding, but new condominium supply is moving in the opposite direction. Investors considering income-producing apartments should focus on rent levels, vacancy and competing rental supply, while owner-occupiers and resale investors need to monitor the limited pipeline of new condominiums. Starts in Tokyo's three central wards reached 610 units, up 13.2% year on year, but scarcity in prime central districts remains a separate issue from aggregate supply growth across the metropolis.
