A high-rise shopping and entertainment hub, with well over 500,000 travelers passing through it each day.
Shinjuku Station in Shinjuku-ku, the "new center of Tokyo," is an immense terminal with a concentration of various rail lines: the JR Chuo, Yamanote, Sobu and Saikyo lines; the Toei Shinjuku and Oedo Subway lines; and private railways such as the Odakyu, Keio and Seibu Shinjuku lines.
Shinjuku can be roughly divided into three areas: the West Exit area, an office town with a row of high-rise buildings such as the Tokyo Metropolitan Government Office Building; the South Exit area, a newcomer to Shinjuku with complex establishments for shopping and amusement; and the prominent entertainment district around Kabukicho, a town that never sleeps. In the East Exit area there is a row of department stores and other large stores, all of which are integrated and linked together.
South of the downtown area around the East Exit is Shinjuku-gyoen National Garden, completed in 1906, it features European gardens designed by a French engineer. This garden park surrounds you in luscious greenery and exudes serenity, completely secluded from the hustle and bustle of metropolitan Tokyo. It is renowned as the best site in the city for viewing flowers and wild birds.
