Nishi-ojima Station
S14 · Shinjuku Line · Koto
Nishi-ojima Station (西大島)
Nishi-ojima opened on 21 December 1978 with the first section of Toei’s Shinjuku Line, and it has the plain shape that stretch of line favors: a concourse and ticket gates on the first basement level, an island platform with two tracks on the second, and four street entrances. Elevators linking exit A4, the gate level and the platform were added in 2006.
The station box sits under the crossing of two Tokyo metropolitan routes, 50 — Shin-Ohashi-dori — and 306, Meiji-dori, which is why the exits are spread around the junction. S14 should not be confused with Ojima, a separate station one stop away on the same line, and Sumiyoshi lies on the other side. Trains here run through onto Keio tracks beyond the far end of the subway.
Finding Nishi-ojima 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-ojima
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
No. They are two separate stations one stop apart on the Shinjuku Line, both in Koto ward and with similar names. Nishi-ojima is S14; make sure the train you want actually calls at the one you need.
The intersection of Shin-Ohashi-dori and Meiji-dori — Tokyo metropolitan routes 50 and 306. The station was built under the crossing, so its four entrances surface at different corners of the junction rather than in one building.
