History of Shinjuku station

Shinjuku station was opened in 1885. It was previously a stop on the Akabane-Shinagawa line (now part of the Yamanote Line).

The opening of highway lines, including Chuo (1889), Keio (1915) and Odakyu (1953), resulted in increased traffic through the station. Subway services with Marunouchi Line at the station started in 1959, while the services of Toei Shinjuku and Toei Oedo lines began in 1980 and 2000 respectively.

Plans were drawn in the past to connect Shinjuku to the Shinkansen network. According to the plans, the station was supposed to be the southern terminal of the Joetsu Shinkansen line to Niigata.
