Mizue Station (瑞江)
Mizue was built with overtaking in mind. The Shinjuku Line extension from Funabori to Shinozaki brought S19 into use on 14 September 1986 — the works had called it Nishi-Mizue — with an island platform on two loop tracks and a through track on each outer side. Walls separate the platform from those outer tracks, so a passing express is heard rather than seen. The Motoyawata-direction through track was only commissioned on 24 December 1997, when express running began on the line; under the timetable introduced on 16 March 2024 no scheduled overtaking happens here at all.
The station sits beneath a building owned by the Tokyo Kotsu Kaikan, in the middle of a residential part of Edogawa, and platform screen doors came into use on 9 June 2018. Trains from here run through onto Keio tracks beyond the subway.
Finding Mizue 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 Mizue
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.

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.

What is near Mizue Station?
Mizue is a commuter station in a residential grid, and almost everything around it is local: Lapark Mizue for shopping, the Tobu Friend Hall and the Tobu Citizen’s Hall for events, and the Mizue Daiichi Hotel. A neighborhood park lies about 170 m from the exits and another roughly 340 m. Keisei buses leave from outside for Koiwa, Shin-Koiwa and Edogawa Sports Land, and the station is the local railhead for a part of the ward the Shinjuku Line serves alone.

Frequently asked questions
The two outer tracks at the station are through tracks, and a wall stands between them and the island platform. The arrangement lets fast trains run past the loop tracks where stopping services wait, which is why the platform feels enclosed.
Yes. The last service of the day from the Shinjuku direction running beyond Ojima terminates at this station rather than continuing to the end of the line, so check the destination on the front of the train if you are traveling late.
