"Roppongi Hills" is an expansive 12.0 hectare site, which is about 8 times the space that Tokyo Dome covers. It features shopping areas and restaurants, as well as art galleries, movie theaters, apartments, offices, a park, and much more. Mori Tower has 52 floors and extends 250m above sea level. It has a 360-degree glass observation deck called "Tokyo City View", and the "Sky Deck" above that offers a wide open space with a complete panoramic view of Tokyo's cityscape.

The observation deck on the 52nd floor of Mori Tower that rises over Roppongi Hills is located almost in the center of central Tokyo. Despite this, there is nothing blocking the view from here, providing you with a 360-degree dynamic view of the scenery.

Tokyo Midtown has a wide variety of places, including shopping centers, office buildings, hotels, art museums, event halls, medical institutions, parking lots, and parks.

A complex city, ARK HILLS, where offices, hotels, residences, a concert hall and a studio gather, has four high-rise buildings.
