The Toei Shinjuku Line (都営地下鉄新宿線, Toei Chikatetsu Shinjuku-sen) is a rapid transit line in Tokyo and Chiba Prefecture, Japan, operated by Tokyo Metropolitan Bureau of Transportation (Toei). The line runs between Motoyawata Station in Ichikawa, Chiba in the east and Shinjuku Station in the west. At Shinjuku, most trains continue as through services to Sasazuka Station on the Keiō New Line, with some services continuing to Hashimoto Station in Sagamihara, Kanagawa via the Keiō Line and the Keiō Sagamihara Line.

On maps and signboards, the line is shown in the color leaf green. Stations carry the letter "S" followed by a two-digit number inside a yellow-green chartreuse circle.

Overview

Unlike all other Tokyo subway lines, which were built to 1,435 mm (4 ft 8+1⁄2 in) or 1,067 mm (3 ft 6 in) gauges, the Shinjuku line was built with a track gauge of 1,372 mm (4 ft 6 in) to allow through operations onto the Keiō network. The line was planned as Line 10 according to reports of a committee of the former Ministry of Transportation; thus the rarely used official name of the line is the "Number 10 Shinjuku Line" (10号線新宿線, Jū-gō-sen Shinjuku-sen).^[2]

According to the Tokyo Metropolitan Bureau of Transportation, as of June 2009 the Shinjuku Line was the third most crowded subway line in Tokyo, at its peak running at 181% capacity between Nishi-ōjima and Sumiyoshi stations.^[3]

It is the only Toei line to run outside Tokyo, and one of only two Tokyo subway lines to run into Chiba Prefecture, the other being the Tokyo Metro Tozai Line. The Tokyo Metro Yūrakuchō Line and the Tokyo Metro Fukutoshin Line are the only other subway lines to run beyond Tokyo, with their shared northern terminus at Wakōshi Station in Saitama Prefecture. All lines that have through services contain at least one route beyond Tokyo, however.
