Akasaka Station (赤坂)
For a while this station was going to be called Hitotsugi – the provisional name was set out in a 1964 government notice while the route was still being fixed – and it took the name Akasaka only when the Chiyoda Line opened here on 20 October 1972 as C06. The platform is a single island on a pronounced curve, a trait it shares with Nogizaka and Kokkai-gijidomae on either side; for decades a member of staff stood on the platform to signal departures to the conductor, a practice dropped in February 2022. Departure melodies were introduced on 27 October 2018, with a different tune for each track.
The station is a single-line stop that nevertheless does heavy work: 80,453 entries and exits on an average day in the 2025 survey, 49th among Tokyo Metro’s 130 stations and the highest figure of any Chiyoda Line station with no connection to another line. Its identity comes largely from one neighbor. The headquarters of Tokyo Broadcasting System sits beside the exits, and automated announcements on the platform and on board name the stop twice and then add TBS-mae.
Finding Akasaka 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 Akasaka
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.
