Shinjuku Sumitomo Building
About
Shinjuku Sumitomo Building (新宿住友ビルディング, Shinjuku Sumitomo Birudingu) is a highrise building in the corner of Shinjuku Shintoshin in Nishi-Shinjuku, Shinjuku-ku, Tokyo. It houses the head office of Sumitomo and is a prominent piece of the Shinjuku, Tokyo, Japan skyline. The building's three-sided construction makes good use of available space, yet the building's design sacrifices valuable floor space by including a massive atrium running the entire height of the building. Construction began in November 1971 and was finished on March 6, 1974. At the time of its completion, its elevators were the fastest in the world at 540 meters per minute. It was the tallest building in Tokyo from March to September 1974 when it was surpassed by the Shinjuku Mitsui Building which is located just to the east of the Sumitomo building.
