The large-scale redevelopment project HARUMI FLAG in Tokyo’s Chuo Ward has been fully completed, with the final two high-rise residential towers now finished. The complex, built on approximately 13 hectares of waterfront land in Harumi, comprises 24 buildings containing a total of 5,632 apartments, along with commercial facilities. With the addition of nursery schools, senior housing, and other amenities, the area is expected to house around 12,000 residents with diverse lifestyles.

HARUMI FLAG was developed on the site of the Tokyo 2020 Olympic and Paralympic Athletes’ Village, implemented by the Tokyo Metropolitan Government. Eleven major developers participated as designated constructors responsible for the construction of the redevelopment buildings.

The two final towers—50 stories above ground and one below, with a combined 1,455 units—were completed and handed over to buyers starting on September 19.

One of the towers stands in the “Sun Village” zone on the western side of the site, designed by Mitsubishi Jisho Design and built by Maeda Corporation. The other, located in the “Park Village” zone to the south, was The other, located in the “Park Village” zone to the south, was designed by Nikken Sekkei in collaboration with Sumitomo Mitsui Construction, which served as the contractor.

The twin towers, positioned at the heart of the district, were designed to complement each other visually.

The Sun Village and Park Village zones each contain seven buildings. In addition, the Port Village area includes four buildings with rental apartments, childcare facilities, and other services, while Sea Village comprises five condominium buildings. A separate commercial facility stands adjacent to these zones. (2025/09/24)
