Tokyo Tatemono Co., Ltd. and Tokyu Fudosan Corporation, as business partners with the executor, the Urban Renaissance Agency (UR), have announced that construction began on the 'Kita-Aoyama 3-chome District Class 1 Urban Redevelopment Project' (Minato-ku, Tokyo) on June 1, 2026, with a groundbreaking ceremony held on the same day.
As part of the Tokyo Metropolitan Government's 'Kita-Aoyama 3-chome Urban Development Project,' this initiative aims to integrally develop the area along Aoyama-dori Avenue and the former site of metropolitan housing. The project will enhance the seismic resistance of buildings, create a vast green space, and form a hub for culture and trends.
The development includes the 'B-1 Block,' a 38-story high-rise building with a total floor area of approximately 178,000 m², comprising offices, a hotel, and retail facilities. It also features the 'B-2 Block,' a 3-story retail building with a total floor area of about 2,000 m². Furthermore, a vast 'wooded belt' spanning approximately 1 hectare, including the preceding development area, will be established.
The project utilizes a business partner system, where Tokyo Tatemono (as the lead company) and Tokyu Fudosan are responsible for acquiring reserve floors, promoting the project, and formulating the overall management and operation plan. Tokyo Tatemono has also been selected as the hotel operator.
## A 1-Hectare 'Wooded Belt' in the Heart of Aoyama's Bustle
A vast 'wooded belt' of about 1 hectare (including the preceding area) will be developed in a rare location near Omotesando and Gaienmae stations.
The planting design and tree selection are supervised by Landscape-plus Inc. Based on ecological surveys, the plan features a variety of seasonal plants, primarily native species. This aims to contribute to biodiversity by serving as a stepping stone in the ecological network connecting nearby large green spaces like Meiji Jingu and the Akasaka Imperial Grounds.
The 'wooded belt' will not only function as a place for office workers to rest and refresh but will also be used for events that promote interaction among local residents and businesses. It is also expected to help address environmental issues such as the urban heat island effect.
## Aoyama's Largest Building and a Mixed-Use Facility with Diverse Functions
The standard office floors (7th to 37th) will offer one of the largest floor plates in the Aoyama area, ranging from approximately 2,800 m² to 3,100 m² per floor. The lower floors are planned to include smaller, divisible sections with balconies.
A lounge space for office tenants is planned for the 4th floor, and the 5th floor will feature facilities for internal and external meetings.
