Ojima Station (大島)
Three tracks and two island platforms give Ojima a job most stations on the Toei Shinjuku Line do not have. The middle pair of tracks leads into the Ojima depot, so trains begin and end their day here, and every express on the line pauses at S15 to connect with a local service — a timetable that looks straightforward elsewhere becomes busy at this one platform.
The station opened on 21 December 1978 beneath the junction of Shin-Ohashi-dori and Kyuhachi-dori, and its trains do not stop at the Toei boundary: Shinjuku Line services run through onto the Keio network west of Shinjuku. Toei counted 31,661 passengers a day in 2024, the lowest total of any express stop on the line, which says something about the place of Ojima in the network: it matters more to the running of the Shinjuku Line than to the number of people who pass through it.
Finding 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 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.

Departure times come from the operators’ own GTFS timetables (ODPT GTFS Toei-Train-GTFS (version 20261009, valid 2026-03-14..2027-03-12) + TokyoMetro-Train-GTFS (version 20261008, valid 2026-09-19..2027-03-12)). Japan publishes two subway timetables: 平日 weekdays and 土休日 Saturdays, Sundays and national holidays. There is no separate Sunday timetable, and the December 30 – January 3 period runs the holiday timetable.

What is near Ojima Station?
The surroundings are a mix of shops, apartments and light industry, with Koto Hospital about 90 m from the exits and the Daiyon Ojima elementary school roughly 140 m away. Small neighborhood playgrounds — the Ojima 6-chome second children’s park at about 180 m, Ojima 4-chome Park and Ojima 5-chome Park a little further — stand in for anything larger. A special-needs school and a second junior high school are also close, and Toei buses from the stop outside run towards Asakusa, Kameido and Kasaibashi.

Frequently asked questions
Because of the track layout. Ojima has three tracks between its two island platforms, and every express on the Shinjuku Line uses the station to connect with a local service, letting passengers from the smaller stations either side join the faster train here. The waiting tracks double as the approach to the depot.
The centre tracks run into the Ojima depot, so the station has its own departures at the start of service and its own arrivals at the end of it. Destination boards showing Ojima are therefore normal rather than a sign of disruption.
