Roppongi Hills

 Roppongi Hills, which was completed about 20 years after the start of its conception, was born based on the concept of "a cultural city center" that was developed based on the idea of "a vertical garden city." Roppongi Hills has complex facilities, including a highly secured office tower as a core of Roppongi Hills, an entertaining art center, a hotel, a studio, and a network of greenery interwoven with the natural environment and historical features.
