Nishi-magome Station (西馬込)
A01 is the southernmost station of the Tokyo subway, and it was built in the expectation of not staying that way. When it opened on 15 November 1968 at the end of Toei Line 1 — the Asakusa Line from 1978 — the designers assumed an extension toward Kawasaki would one day make it an intermediate stop, so instead of the island platform usual for a terminus they built two side platforms, with the reversing crossover placed beyond the station and the sidings laid out for a line that might continue.
Two other consequences of being a dead end show up here. Cooling was installed from the first day, because trains standing to reverse shed heat from their resistors and no through traffic pushes the air along. And the Magome depot lies just beyond the buffers, maintaining stock for the Asakusa Line and for the Oedo Line, whose trains reach it through a connecting tunnel near Shiodome. The east exit opened on 30 March 2013, and in November 2023 Nishi-magome became the last Toei station to receive platform doors.
Finding Nishi-magome 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-magome
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.

Transfers and connections
Only the Asakusa Line stops here, and no other railway serves this station, so there is nothing to transfer to inside the station.

What is near Nishi-magome Station?
Ota ward at this point is houses and small workshops along the Daini Keihin highway, which the station runs beneath. It is one of the closest stations to the temple of Ikegami Honmon-ji, which is the main reason a visitor would come out here; otherwise the surroundings are local — four small parks between 280 m and 330 m from the exits, an elementary school about 400 m, a car dealership roughly 180 m — and the depot occupies much of the land on the far side.

Frequently asked questions
Because it was not meant to stay a terminus. The Asakusa Line was expected to be extended toward Kawasaki, which would have made Nishi-magome an ordinary through station, so side platforms were built rather than the island layout normal at the end of a line; the depot connections beyond the platforms also ruled out an island.
The Magome works, just beyond the station, maintains rolling stock for both Toei subway lines. Oedo Line trains reach it by running onto the Asakusa Line through a connecting tunnel near Shiodome, since the two networks are otherwise separate.
