Higashi-ojima Station (東大島)
Higashi-ojima is a station built as a bridge. Its two side platforms span the Kyu-Naka river on a series of spans, with one entrance on the Koto bank and the other in Edogawa, so the ward boundary runs through the station – there is a marker on the platform showing where. That oddity earned it a place among the hundred selected stations of the Kanto region in 2000.
It opened on 21 December 1978 as the end of the Shinjuku Line and became an intermediate stop on 23 December 1983 when the line was extended to Funabori. The ground here lies below sea level, so the structure was set above A.P. +3.5 m against flooding and the platforms stand about 12 m above the water. The whole station sits on a curve of 600 m radius, which is why a member of staff is posted on the platform through most of the day. Toei has used it as a test bed for solar and wind power, rainwater collection and rooftop planting; mist sprayers cooled the platform each summer until 2016, and air-conditioned waiting rooms replaced them in June 2018. The 2024 count was 30,424 entries and exits a day.
Finding Higashi-ojima 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 Higashi-ojima
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.
