A 5,632-unit district across roughly 18 hectares

The Tokyo Metropolitan Government's updated outline of the Harumi 5-chome West Urban Redevelopment Project describes a large mixed residential and commercial district in Chuo Ward. The roughly 18-hectare area contains 21 mid- and high-rise residential blocks, two approximately 180-meter, 50-story residential towers and one commercial building. Total housing supply is 5,632 units, including 4,145 units for sale and 1,487 rental units. Facilities originally used as accommodation for athletes during the Tokyo 2020 Games were converted and supplemented with post-Games construction to form a permanent residential neighborhood.

Large-scale supply can influence the wider waterfront market

Sites capable of accommodating thousands of new homes are scarce in central Tokyo, where land availability and construction costs constrain development. Harumi is therefore significant not simply as a condominium project but as the creation of an entire residential stock in one district. The arrival of thousands of households can affect local retail demand, rental supply, resale competition and the relative positioning of older waterfront condominiums. The presence of both owner-occupied and rental inventory also makes the project relevant to multiple segments of Tokyo's housing market.

Overseas buyers should evaluate the district, not only individual units

Foreign and non-resident buyers considering Tokyo Bay properties may need to look beyond unit size, floor level, view and acquisition price. Transport access, commercial amenities, management quality, future competing supply and the maturity of the surrounding neighborhood can all affect long-term usability and resale liquidity. Large developments expand buyer choice, but periods when multiple owners list similar units for sale or rent can also increase competition. Harumi will remain an important indicator of how far central Tokyo housing demand continues to extend into the waterfront districts.
