Sengoku Station (千石)
Sengoku was nearly called Kagomachi. That was the old name of the district, and a 1919 transport study for the city had already pencilled in a Kagomachi station on a planned Shibuya–Otsuka line; the provisional name stayed on the drawings until shortly before opening. What opened, on 30 June 1972, was a station on Toei Line 6 — the Mita Line did not take that name until 1 July 1978.
The platform is a single island with a ticket hall at either end, running under Hakusan-dori from the Shinobazu-dori crossing to the point where the old and new stretches of Hakusan-dori part company. I14 is the northernmost station in Bunkyo, and Toei’s 2024 survey counted 31,304 passengers a day.
Finding Sengoku 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 Sengoku
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.

What is near Sengoku Station?
Everything near the exits is small in scale: the ward’s Sengoku library about 120 m away, Kagomachi Park about 130 m, and a string of children’s playgrounds — Sengoku 1-chome, Sengoku 4-chome, Hayashicho — filling the gaps between apartment blocks. Hiroo Gakuen Koishikawa junior and senior high school stands roughly 200 m from the station and a kindergarten about 260 m, with the Sengoku green space and Sengoku Park further out. The Rikugien garden and the Toyo Bunko library are among the places the station serves.

Frequently asked questions
Kagomachi, after the former name of the neighborhood. A 1919 study of Tokyo’s transport had already listed a Kagomachi station on a planned Shibuya–Otsuka route, and the name survived as the working title until shortly before the station opened in 1972.
Because that is what the Mita Line was called at the time. Sengoku opened on 30 June 1972 as a station on Toei Line 6, and the line was renamed the Mita Line on 1 July 1978. Plans and photographs from the first six years use the old name.
