Ark Hills (アークヒルズ, Āku Hiruzu) is a major office development by Mori Building Company in Minato, Tokyo. Opened in 1986, the complex includes the Ark Hills Sengokuyama Mori Tower, the Ark Mori Building, the ANA InterContinental Tokyo Hotel, the world-class Suntory Hall concert hall, a TV studio and several apartment buildings. TV Asahi still uses its former headquarters as an annexe for some of its departments and subsidiaries; the network's headquarters themselves were moved to the nearby building designed by Fumihiko Maki in 2003. Every year the area celebrates the autumn festival Ark Hills Music Week, that includes music, dancing, food, art and shopping.[1]

The name "Ark" is derived from the location of the complex, at the intersection of the Akasaka, Roppongi and Kasumigaseki districts. Another explanation is that the name stands for Akasaka and Roppongi knot.[2] The complex lays on a slight slope, rather than a hill.

The heliport on the roof of the Ark Mori Building used to provide direct flights between Ark Hills and the Narita International Airport (approximately 20 minutes), until it was discontinued on December 1, 2015.[3]
