Ark Hills is a major office development by Mori Building Company in Minato, Tokyo. Completed in 1986, the complex includes the ANA InterContinental Tokyo Hotel, the ARK Mori Building, 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. Every September the area celebrates with an autumn festival that includes music, dancing, food, art, and shopping.
