Nishidai Station (西台)
Nishidai opened on 27 December 1968 with the first section of Toei Line 6, the future Mita Line, as a pair of elevated side platforms in what was then the edge of Itabashi. The feature that matters operationally is next door: the Shimura depot adjoins the station, so this is where train crews change over, and the yard dominates the view from the platform.
The passenger side has grown slowly. A second entrance was added on 31 March 2004 and the original one renamed the East Exit; the West Exit was completed in 2005 together with an elevator, left unstaffed from December 2008 and then given full first-train-to-last-train hours from 1 March 2009. A waiting room opened on platform 1 on 24 March 2015, and since 22 January 2016 an advertisement for Daito Bunka University has hung under the station name board — a reminder that the university’s shuttle traffic is part of what the station does. Takashimadaira and Hasune are the stations either side.
Finding Nishidai 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 Nishidai
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.
First and last trains at Nishidai
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.

Frequently asked questions
It is an advertisement, placed under the station name sign on 22 January 2016. The university is one of the destinations people use Nishidai for, and the sign serves as a pointer for students unfamiliar with the area.
Because the Shimura depot is next to the station. Toei stables and maintains Mita Line trains there, and the crew office attached to the depot makes this a natural place to hand trains over from one driver to the next.
