The Nishiazabu 3-Chome Northeast District First-Class Urban Redevelopment Project is a first-class urban redevelopment project underway around Nishiazabu 3-chome and Roppongi 6-chome in Minato City, Tokyo, on the west side of Roppongi Hills. The project implementer is the Nishiazabu 3-Chome Northeast District Urban Redevelopment Association, with Nomura Real Estate Co., Ltd. and Ken Corporation participating as association members. The project area is about 1.6 hectares, and the plan sits where the dense urban functions on the Roppongi side meet the established urban fabric on the Nishiazabu side. The plan is not limited to replacing buildings; it also reorganizes the district by including roads, pedestrian passages, plaza-like spaces, and green areas.
At the center of the project, Block A is planned as a mixed-use tower with 54 stories above ground, 4 basement levels, a height of 199.98 meters, a maximum height of 201.20 meters, and a total floor area of 96,832 square meters. The total number of units is 498, with residences located from the 6th to the 45th floors and the hotel from the 46th to the 52nd floors, while the lower floors are planned to house retail and office space. Block A began construction in late March 2025 and is scheduled for completion in late December 2029.
Prior to that, development in Blocks B2 and B3 has been moving forward, including the temporary relocation of Choko-ji Temple and Sakurada Shrine, and they are currently announced as having started construction in December 2024 and scheduled for completion in July 2026. In April 2019, the schedule showed a fiscal 2020 start and fiscal 2025 completion, but it was later updated to the current schedule after approval of the rights conversion plan and other procedures. At present, construction of the supertall tower and reorganization of the surrounding blocks, including the temple and shrine, are becoming concrete in stages.

Plan Features
The biggest feature is the vertical stacking of residences, a hotel, retail, and offices in the roughly 200-meter-class tower of Block A. While the plan publicly states that residences will occupy the 6th through 45th floors and the hotel will occupy the 46th through 52nd floors, the hotel brand name, unit size composition, and the detailed floor allocation for offices and retail are not disclosed in the available public materials. This vertical stacking positions the project as one that integrates living, staying, working, and visitor functions in the area adjacent to Roppongi Hills.
The project is also distinctive in that it is not simply the construction of a single supertall building, but includes phased block reorganization. In Blocks B2 and B3, work is already underway with the temporary relocation of Choko-ji Temple and Sakurada Shrine, forming a framework for advancing the redevelopment while adjusting to the existing religious facilities and surrounding rights relationships. Under the redevelopment association framework, the project separates the schedule between Block A and Blocks B2 and B3, while ultimately reconfiguring them into a single urban infrastructure.
Urban infrastructure updates include the widening of Auxiliary Route No. 10, improvements to block roads, better pedestrian circulation, and the development of pedestrian decks. The site sits at the interface between the dense urban fabric behind Roppongi-dori and the narrow streets on the Nishiazabu side, making the organization of vehicle and pedestrian flows, improved disaster resilience, and secure evacuation performance important goals of the redevelopment. The retail spaces on the lower floors, plaza-like spaces, green areas, and pedestrian passages are positioned as core elements of the block reorganization, just like the internal mix of uses within the building.
Relationship with Surrounding Projects and the Area
The project site is located on the west side of Roppongi Hills, near the large-scale office and commercial concentration around Roppongi Station, while on the Nishiazabu side it sits at a boundary area where residential neighborhoods, temples and shrines, and existing streets remain. For that reason, this project is not simply an extension of the high-rise, high-density urban space on the Roppongi side; it also serves to reconnect with the Nishiazabu side through Television Asahi-dori, Auxiliary Route No. 10, block roads, and pedestrian passages. The location itself makes this a redevelopment that asks not only about the building but also about the quality of block connectivity.
What is especially important in relation to the surrounding area is improved walkability and circulation toward Roppongi Hills. Public materials show the development of pedestrian decks and pedestrian networks, and after completion this may change the flow of people moving from the Roppongi side toward Nishiazabu. If the retail spaces on the lower floors, plaza-like spaces, and pedestrian passages function as intended, the redevelopment building will not only become a new destination in itself, but also reshape movement routes and lingering points between existing blocks.
In addition, this plan is notable for advancing in the Nishiazabu area adjacent to Roppongi within Minato City’s central district, where large-scale redevelopment continues around the area. As shown by the fact that Block B2 and B3 are being developed first with the relocation of temples and shrines, this is a reconfiguration premised on coordination with existing assets, not a simple clear-site redevelopment. With the supertall development of Block A, the advance work in Blocks B2 and B3, and the renewal of roads and pedestrian infrastructure combined, this project should be understood as creating a new interface between the urban functions on the Roppongi side and the streetscape on the Nishiazabu side.
INA Brief
The essence of the Nishiazabu 3-Chome Northeast District redevelopment lies less in the construction of a roughly 200-meter mixed-use tower itself than in the reorganization of the boundary block west of Roppongi Hills together with temple and shrine relocation, road improvements, and pedestrian circulation updates. The schedule is now concrete, with Block A starting in late March 2025 and Blocks B2 and B3 starting in December 2024, and the eventual evaluation will depend on how the lower-floor spaces and pedestrian network connect the Roppongi side and the Nishiazabu side after completion.
