Shinjuku (Japanese: 新宿区, Hepburn: Shinjuku-ku, IPA: [ɕiɲdʑɯkɯ] ^ⓘ), officially called Shinjuku City, is a special ward of Tokyo, Japan. It is a major commercial and administrative center, housing the northern half of the busiest railway station in the world (Shinjuku Station) as well as the Tokyo Metropolitan Government Building, the administrative center of the Tokyo Metropolitan Government. As of 2018^[update], the ward has an estimated population of 346,235 and a population density of 18,232 people per km². The total area is 18.23 km².^[4] Since the end of World War II, Shinjuku has become a major secondary center of Tokyo (fukutoshin), rivaling the original city center in Marunouchi.

"Shinjuku" is also commonly used to refer to the entire area surrounding Shinjuku Station. The southern half of this area and of the station are in fact located in the neighboring Shibuya ward.
