“Subway services at the station started in 1959.”

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 – Chuo, Keio and Odakyu – resulted in increased traffic through the station. Subway services at the station started in 1959.

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 Jōetsu Shinkansen line to Niigata. At present Jōetsu line terminates at Tokyo Station.
