Older mixed-use building to become housing

The Tokyo Metropolitan Government announced on August 19 the first project selected under its renovation-based affordable-housing challenge. Yasuda Real Estate's project in Kanda Nishikicho, Chiyoda Ward, will renovate a mixed-use building constructed under older seismic standards into affordable residences together with shops and other community-facing uses. Residential rents are to be calculated using 80% of rents for comparable nearby housing as a benchmark. Design or construction is scheduled to begin during fiscal 2026, with renovation expected to be completed in fiscal 2027.

Existing buildings become part of housing-supply policy

High land and construction costs make it difficult to expand affordable housing in central Tokyo through new development alone. The program therefore focuses on adapting existing building stock. Converting offices or older mixed-use buildings can add residential supply without following the same development model as demolition and full reconstruction. The economics remain complex because seismic upgrading, building services, change-of-use requirements and renovation costs can materially affect project feasibility.

A new reference point for surrounding rental owners

Housing priced around 80% of comparable local rents can create a new reference point for nearby tenants and landlords, although the impact on the broader market will depend on the number of units and eligibility requirements. For investors, the larger significance is the emergence of a concrete model combining adaptive reuse and public policy support in central Tokyo. Future rental-market analysis should therefore consider not only newly built apartments but also office-to-residential conversions and renovation of older stock.
