Shinjuku Sumitomo Building is a highrise building in super 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.
