Nishi-shinjuku Station (西新宿)
For forty years there was a two-kilometer gap in the Marunouchi Line between Shinjuku and Nakano-sakaue, and the tunnel had been built with a station in mind. Redevelopment west of Shinjuku finally justified it: work started in May 1992, the name was settled on 9 November 1995, and M07 opened on 28 May 1996 at a cost of ¥6.43 billion — the first new station on the line in thirty-one years and eight months.
During construction the project was called Eidan Nishi-shinjuku, because Toei was then using Nishi-shinjuku as the working name for what became Tochomae on its own line. The finished station has two side platforms with the concourse floor spread above both of them, so either entrance leads to either direction, a convenience that is rarer than it sounds. Its secondary name is Tokyo Medical University Hospital, after the hospital it serves.
Finding Nishi-shinjuku on the signs
Every line gives the station its own letter-and-number code. You never have to read the Japanese name to find the right platform.
Station numbers at Nishi-shinjuku
Tokyo signposts every platform, exit and train door with a letter and a two-digit number. Matching the number is faster than reading the name — and it is what you will see on the map, in announcements and on the platform edge.

Frequently asked questions
To fill a gap. The distance from Shinjuku to Nakano-sakaue was about two kilometers, long for this line, and the tunnel had been built so that a station could be inserted later. The redevelopment of western Shinjuku made the case, and the station opened on 28 May 1996.
Tokyo Medical University Hospital. Tokyo Metro adds the hospital’s name to signage at M07 because the hospital is one of the main destinations the station serves, in the same way other stations carry a landmark as a second name.
