Kasai Station

Kasai Station (葛西)
Kasai carries a second name on its signs: Chikatetsu Hakubutsukan-mae, in front of the Subway Museum. The museum opened under the viaduct on 12 July 1986, and from 1 August 1993 it got its own ticket gate at one end of platform 2, which shuts after 23:00. The station itself opened on 29 March 1969 as T17, elevated, with two side platforms set outside a pair of central tracks that rapid trains use to overtake – during the middle of the day every rapid on the Tozai Line passes a local here.
The other thing Kasai is known for is underground and has nothing to do with trains: the automated bicycle park completed in April 2008, which stores about 9,400 bicycles in a basement 15 m deep and returns one in roughly 23 seconds, each of its lifts handling 180 to 190 machines. Solar panels went up in 2013 and platform doors came into use on 4 December 2021. With 100,966 entries and exits a day in the 2025 survey, this is the most heavily used of the stations that rapid trains skip between Toyocho and Nishi-funabashi.
Finding Kasai 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 Kasai
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 Kasai
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.
