Oji-kamiya Station (王子神谷)
Two neighbouring district names were welded together to make this one: Oji and Kamiya. The prefix is not decoration — it keeps the station apart from Kamiyacho on the Hibiya Line, which would otherwise be easy to confuse. While the line was being planned the working name was Kamiyabashi, and N17 finally opened with the first stretch of the Namboku Line on 29 November 1991.
The layout is unusual for the line: two side platforms rather than an island, a configuration the Namboku Line repeats only at Shirokanedai. Below the concourse the station connects to the Oji depot, and that link shapes the timetable, with trains entering service here in both directions and some arrivals going no further. Tokyo Metro counted 37,603 passengers a day in 2025.
Finding Oji-kamiya 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 Oji-kamiya
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.

What is near Oji-kamiya Station?
This is a quiet stretch of Kita City rather than a destination: blocks of public housing, an elementary school about 180 m from the exits, and two small parks, the Oji 5-chome apartment community park roughly 170 m away and Kamiyabori Park about 280 m. A pharmacy sits near the entrances. The depot beside the station takes up much of the immediate surroundings, and a freight station that closed in 2014 once stood on the other side of it.

Frequently asked questions
It joins two adjoining district names, Oji and Kamiya. Oji was put in front partly to prevent confusion with Kamiyacho on the Hibiya Line, a different station in a different part of the city. Before opening, the planned name for the site was Kamiyabashi.
The Oji depot adjoins the station below ground, so trains can enter and leave service here. The timetable includes departures that start at this station in both directions, as well as arrivals that terminate rather than carrying on, which is unusual for a station in the middle of a line.
