Toranomon Hills

Tokyo, JAPAN

Toranomon Hills (虎ノ門ヒルズ Toranomon Hiruzu?) is a skyscraper complex project built by Mori Building in the Toranomon district of Minato, Tokyo, Japan. Designed by Nihon Sekkei, it is built around the new Loop Road No. 2, a surface artery that will connect the Shinbashi and Toranomon districts.

Its highest point is 255.5 metres, by which measure it is the tallest building in Tokyo. However, its building height is 247 metres, by which measure it will be the second-tallest building in Tokyo after Midtown Tower.

The complex has a logo made of four black vertical bars forming a letter “M” (and also resembling the “門” kanji of the Toranomon name). It also has a mascot called Toranomon (トラのもん?) inspired by the Japanese manga character Doraemon.


There have been plans since 1946 to build a new arterial road between Toranomon and Shimbashi as part of a loop road around central Tokyo. The Toranomon segment was popularly referred to as the “MacArthur Road” after General Douglas MacArthur, who led the Allied liberation of Japan following World War II, making reference to the proximity of the United States Embassy compound in nearby Akasaka. The plan remained unrealized for decades due to the government’s inability to expropriate the necessary prime real estate in central Tokyo, but a solution was finalized around 1989 which involved building a new skyscraper above the road and offering to relocate displaced residents into the skyscraper.

The project’s provisional name was Loop Line No. 2 Shimbashi/Toranomon Redevelopment Project Building III (環状二号線新橋・虎ノ門地区第2種市街地再開発事業Ⅲ街区?). Mori Building formally announced the Toranomon Hills name on March 1, 2013.
