Nijubashimae Station
C10 · Chiyoda Line · Chiyoda
Nijubashimae Station (二重橋前)
The planners called it Iwaidacho in 1925 and Babasakimon in 1964; when C10 finally opened on 20 March 1971 it took its name from the Nijubashi, the double bridge at the entrance to the Imperial Palace. That name has confused people ever since, because the station stands among the office blocks of Marunouchi, so on 17 March 2018 Tokyo Metro added “(Marunouchi)” as an official secondary name to say where it actually is.
The Chiyoda Line platform is a single island with an unusual number of ways out: permanent gates at the Otemachi and Hibiya ends, another serving the elevator, and a fourth in the middle of the platform that is opened only occasionally. Departure melodies arrived on 27 October 2018 and platform doors on 3 November that year. The Toei Mita Line passes close by underground but has no platforms here.
Finding Nijubashimae 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 Nijubashimae
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 Chiyoda Line stops here, and no other railway serves this station, so there is nothing to transfer to inside the station.

Frequently asked questions
Because the main name says little about the location. Nijubashimae refers to the palace bridge, but the station serves the Marunouchi office district, so Tokyo Metro added Marunouchi as a secondary name on 17 March 2018 to make that clear and to spread traffic among the stations in the area.
Yes, underground. A passage containing the Gyoko-dori Underground Gallery links the two stations, so you can make the connection without going up to street level — useful in bad weather, though it is a walk rather than a platform-to-platform change.
