Kasumigaseki Station
M15 H07 C08 · Marunouchi Line, Hibiya Line, and Chiyoda Line · Chiyoda
Kasumigaseki Station (霞ケ関)
Three lines serve the government district from here, arriving over thirteen years: the Marunouchi Line on 15 October 1958, the Hibiya Line on 25 March 1964 and the Chiyoda Line on 20 March 1971. The Marunouchi Line has an unusual arrangement – an island platform and a side platform between them serving two tracks, with one face of the island fenced off – and the Chiyoda and Marunouchi platforms do not connect directly: passengers changing between them walk through the Hibiya Line platform, a journey of about five minutes.
The station is bound up with the worst day in the subway’s history. On 20 March 1995 it was one of the targets of the sarin attack, and five days earlier the same group had tried to release botulinum toxin here, an attempt that caused no known casualties. Today it is one of the busier stations on the network, with 136,303 entries and exits a day in the 2025 survey across its three lines, and TH Liner services have called since 6 June 2020.
Finding Kasumigaseki 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 Kasumigaseki
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.
