Toei Shinjuku Line
Subway line in Tokyo, Japan
From Wikipedia, the free encyclopedia
The Toei Shinjuku Line (都営新宿線, Toei Shinjuku-sen) is a rapid transit line in Tokyo and Chiba Prefecture, Japan, operated by the municipal Toei Subway. The line runs between Motoyawata in Ichikawa, Chiba in the east and Shinjuku in the west. At Shinjuku, most trains continue as through services to Sasazuka on the Keiō New Line, with some services continuing to Hashimoto 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 lime green circle.
In fiscal year 2023, the Shinjuku Line was Toei's third most profitable line, earning ¥6.25 billion in surplus. It served 704,235 passengers on average per day, the second highest in the Toei network (after the Oedo Line).[2]
The name “Shinjuku Line” dates to 1903, when a Tokyo tram line of the same name opened, operating above ground between Shinjuku and Yotsuya, along the same route of the present-day Tokyo Metro Marunouchi Line. The name predates the Seibu Shinjuku Line, which was renamed from the Murayama Line in 1952.[3]

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).[4]
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%[a] capacity between Nishi-ōjima and Sumiyoshi stations.[5]
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, the Tokyo Metro Fukutoshin Line and the Tokyo Metro Tozai Line are the only other subway lines to run beyond Tokyo, with the shared northern terminus of the first two at Wakōshi Station in Saitama Prefecture, and the eastern terminus of the Tozai Line being at Nishi-Funabashi Station in Chiba Prefecture. However, all lines that have through services contain at least one route beyond Tokyo.
History
In April 1968, the Urban Transportation Council proposed Line 10 as a route running from Roka-koen via Shinjuku and Yasukuni-dōri, passing through Ichigaya, Jimbochō, Sudachō, and Hamachō, and terminating at Sumiyoshichō.[6]
Following this recommendation, the Ministry of Construction issued Notice No. 3731 on December 28 of the same year, formally approving the construction of the Shinjuku–Sumiyoshichō section (12.5 km) as Line 10, officially designated the Tokyo Metropolitan Rapid Transit Line No. 10.[6] On 20 May 1969, Notice No. 2430 extended the planned route by incorporating the Keio Line between Chōfu and Shinjuku and further extending the urban planning area to Higashi-Ōjima, the site of the line’s depot, bringing the total planned length to 31.2 km.[7]
On 1 May 1971, construction began near Morishita and Sumiyoshi.
Subsequently, in March 1972, Urban Transportation Council Report No. 15 added the sections between Hashimoto, Tama New Town Chuo, Chofu, and Roka Koen, as well as between Sumiyoshi-cho, Higashi-Ojima, Shinozaki-cho, Motoyawata, Kashiwai, northern Kamagaya, the Chiba New Town Komuro area, and the Chiba New Town Inba area. Additionally, it was decided that the section between Chofu and Shinjuku would be double-tracked as part of the Keio Line. Of these routes, the section between Shinjuku and Motoyawata opened in stages as the Toei Shinjuku Line, the section between Hashimoto and Chofu opened as the Keio Sagamihara Line, and the section between Sasazuka and Shinjuku opened as an extension of the Keio Line (the Keio New Line).[7]
