Nishi-takashimadaira Station (西高島平)
I27 is the northernmost station on the Tokyo subway and the end of the Mita Line, opened on 6 May 1976 and used that day to trial the first automatic ticket gates the Toei subway had. It is elevated, with two side platforms that both face the same way — an arrangement shared with only a couple of other dead ends on the network, Nishi-magome and Kita-ayase — and its layout copies that of Shin-takashimadaira, the station before it, so exactly that at the opening the two could be told apart mainly by the color of the gates.
The viaduct stops just short of the Shin-Omiya bypass, which leaves little room for a train that overruns, so hydraulic buffer stops were fitted. Carrying the structure across the road was examined, both for extra safety margin and with an extension toward Omiya in mind, but it would have required permission to build over a national highway and the plan was dropped. Every train here reverses for the run back toward Mita.

Station numbers at Nishi-takashimadaira
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 Nishi-takashimadaira Station?
The station serves a thinly built corner of Itabashi near the bypass, and there is very little within walking distance: a park about 320 m from the single exit, and otherwise low-rise housing and light industry. It is among the quietest places on the network, with Toei counting 12,970 entries and exits a day in its 2024 survey — a fraction of what the other end of this line handles.

Frequently asked questions
The viaduct ends at the Shin-Omiya bypass. Extending it across the road was studied, partly to lengthen the safety margin beyond the platforms and partly with a view to continuing toward Omiya, but it would have meant building over a national highway and the idea was abandoned; buffer stops mark the end of the line.
Yes, of the whole network, which is a little misleading — it lies at the end of a line that runs out into Itabashi rather than in any sense at the top of the city. All trains reverse here and head back toward central Tokyo.
