Azabudai Hills (麻布台ヒルズ,Azabudai Hiruzu) is a complex of three skyscrapers in theAzabudai business district in the ward ofMinato,Tokyo, Japan. Upon its completion in 2023, the Azabudai Hills Mori JP Tower in the development became thetallest building in Tokyo andJapan, surpassingAbeno Harukas inOsaka. The complex is also the largest skyscraper development in Japan by floor area while the Azabudai Hills Mori JP Tower currently serves as thelargest skyscraper in the world by floor area.[3]
The complex was developed by theMori Building Company at a project cost of about 640 billionyen ($5.3 billion).[4] Negotiations with landowners and residents on the site started in March 1989, and the redevelopment was authorised by the government in September 2017. The construction started in August 2019 and was completed in 2023. The architectural firmPelli Clarke Pelli Architects won the contract for the exterior design of the skyscrapers, whileSou Fujimoto andThomas Heatherwick were commissioned to design the interiors and the exteriors of the low-level structures respectively.[5][4]
The complex lies between sister Mori Building projectsRoppongi Hills to the west,Toranomon Hills to the east, andArk Hills to the north. The complex is also directly connected to theKamiyachō Station of theHibiya Line and both the Toranomon-Gochōme and Azabudai Hills bus stations of theToei Bus, while also sharing a close distance to theRoppongi-itchōme Station of theNamboku Line from the northwest.

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.[6]Azabudai Hills consists of three buildings: Azabudai Hills Mori JP Tower, Azabudai Hills Residence A and Azabudai Hills Residence B.[7] Mori JP Tower, measuring 325.2 metres (1,067 ft) and featuring 64 floors, was the firstsupertall to be built in Tokyo. Its appearance was designed to complement the nearbyArk Hills Sengokuyama Mori Tower, a project by the same architect and developer located 250 metres (820 ft) away. The two accompanying buildings, Residence A and Residence B, measure 237.2 and 262.8 metres (778 and 862 ft) in height and feature 54 and 64 floors.[8] The three skyscrapers were designed byPelli Clarke Pelli Architects, the firm of Argentine architectCésar Pelli. Upon completion in 2023, the Azabudai Hills Mori JP Tower became the tallest building in Tokyo, surpassing the nearbyToranomon Hills Station Tower, as well as in Japan, surpassingOsaka'sAbeno Harukas.[5][9]

Accompanying the skyscrapers are a series of low-rise buildings that creates a landscapepergola, designed by London-basedHeatherwick Studio.[10] The 8.1-hectare (20-acre) area is surrounded by lush greenery and features 24,000 m2 (260,000 sq ft) of green space, including a 6,000 m2 (65,000 sq ft) central square, 214,500 m2 (2,309,000 sq ft) of office spaces, 3,300 m2 (36,000 sq ft) of two-level working space named the Hills House located at the 33rd and 34th floors, and 23,000 m2 (250,000 sq ft) of retail spaces, which features 150 shops.[11][12] According to Mori, the design embodies the concept of a "modern urban village". Additionally, 9,000 m2 (97,000 sq ft) of cultural facilities will also be included.[13][14][15] The complex is also a Platinum-levelLEED-certification in two categories, the LEED Core and Shell Development (BD+C) and the LEED Neighborhood Development (ND).[15]

The project has a total floor area of 861,700 m2 (9,275,000 sq ft),[4] including 213,900 m2 (2,302,000 sq ft) of office space and approximately 1,400 residential units.[13] The main tower is the largest skyscraper by floor area in Japan and the world. The main building, known as the Mori JP Tower, 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, which is named the Aman Residences Tokyo.[16] Some media outlets have reported that the largest units of the residential floors in the main tower were sold for approximately 2 billion yen each.[17][18] The complex's low-rise residential complex is the Azabudai Hills Garden Plaza Residence, which features 31 residential units located on the 6th to 8th floors of the Garden Plaza B Mall.[15]
The lower floors also include a supermarket and a multi-language child care facility, as well as an international school,The British School in Tokyo.[11][19] It is projected that the complex will house offices for about 20,000 workers and residences for about 3,500 people.[13]
