Azabudai Hills

Azabudai Hills (麻布台ヒルズ) is a complex of three skyscrapers in Tokyo, Japan. Upon its completion in 2023, the Azabudai Hills Mori JP Tower in the development became the tallest building in Tokyo and Japan.

Designed by the architectural firm Pelli Clarke Pelli Architects and developed by the Mori Building Company, it is estimated that the project will cost about 580 billion yen ($4.4 billion). Construction started in 2019 and was completed in 2023.

The complex is located in the Toranomon business district, in the ward of Minato; it lies between sister Mori Building projects Roppongi Hills to the west, Toranomon Hills to the east and Ark Hills to the north.

Design
Tentatively known as the Toranomon-Azabudai District or Toranomon-Azabudai Project, its official name, "Azabudai Hills", was announced by Mori Building on 14 December 2022. Azabudai Hills consists of three buildings: Azabudai Hills Mori JP Tower, Azabudai Hills Residence A and Azabudai Hills Residence B. Mori JP Tower, measuring 325.2 m and featuring 64 floors, was the first supertall to be built in Tokyo. Its appearance was designed to complement the nearby Ark Hills Sengokuyama Mori Tower, a project by the same architect and developer located 250 m away. The two accompanying buildings, Residence A and Residence B, measure 237.2 and 262.8 m in height and feature 54 and 64 floors. The three skyscrapers were designed by Pelli Clarke Pelli Architects, the firm of Argentine architect César Pelli. Upon completion in 2023, the Azabudai Hills Mori JP Tower became the tallest building in Tokyo, surpassing the nearby Toranomon Hills Station Tower, as well as in Japan, surpassing Osaka's Abeno Harukas.

Accompanying the skyscrapers are a series of low-rise buildings that plan to create a landscape pergola, designed by London-based Heatherwick Studio. The 8.1 ha area will be surrounded by lush greenery and will feature 24,000 m2 of green space, including a 6,000 m2 central square. According to Mori, the design embodies the concept of a "modern urban village". Additionally, 9,000 m2 of cultural facilities will also be included.

Usage
The project will have a total floor area of 860,400 m2, including 213,900 m2 of office space and approximately 1,400 residential units. The main building contains office space in lower and middle floors, while residential spaces will be located on the upper floors, from the 56th to the 65th floor. The lower floors will also include a supermarket and a multi-language child care facility, as well as an international school, The British School in Tokyo. It is projected that the complex will house offices for about 20,000 workers and residences for about 3,500 people.
