The {{Nihongo|'''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 the municipal [[Toei Subway]]. The line runs between {{STN|Motoyawata|x}} in [[Ichikawa, Chiba]] in the east and {{STN|Shinjuku|x}} in the west. At Shinjuku, most trains continue as [[through train|through services]] to {{STN|Sasazuka|x}} on the [[Keiō New Line]], with some services continuing to {{STN|Hashimoto|x|Kanagawa}} in [[Sagamihara, Kanagawa|Sagamihara]], [[Kanagawa Prefecture|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.

In fiscal year 2023, the Shinjuku Line was Toei's third most profitable line, earning 6.25 billion yen in surplus. It served 704,235 passengers on average per day, the second highest in the Toei network (after the [[Toei Oedo Line|Oedo Line]]).<ref>{{Cite web |title=令和4年度 地下鉄路線別収支状況 |trans-title=FY2023 Revenue and expenditure by subway line |url=https://www.kotsu.metro.tokyo.jp/about/information/closing/pdf/r05_closing04.pdf |url-status=live |archive-url=https://web.archive.org/web/20250528095332/https://www.kotsu.metro.tokyo.jp/about/information/closing/pdf/r05_closing04.pdf |archive-date=28 May 2025 |access-date=28 May 2025 |website=Toei Transportation Online |language=ja |format=PDF}}</ref> 

==Basic data==
*Double-tracking: Entire line
*[[Railway signalling]]: D-[[Automatic Train Control|ATC]]

==Overview==
Unlike all other Tokyo subway lines, which were built to {{RailGauge|1435mm}} or {{RailGauge|1067mm}} gauges, the Shinjuku line was built with a track gauge of {{RailGauge|1372mm}} 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 {{Nihongo|"Number 10 Shinjuku Line"|10号線新宿線|Jū-gō-sen Shinjuku-sen}}.<ref>{{Nihongo||[[:ja:鉄道要覧]]|Tetsudō Yōran}}, annual report</ref> 

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%{{Ref label|notes1|a|}} capacity between [[Nishi-ōjima Station|Nishi-ōjima]] and [[Sumiyoshi Station (Tokyo)|Sumiyoshi]] stations.<ref>''[[Metropolis (free magazine)|Metropolis]]'', [http://archive.metropolis.co.jp/tokyo/794/page2.asp "Commute", June 12, 2009, p. 07.] Capacity is defined as all passengers having a seat or a strap or door railing to hold on to.</ref>

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]]. However, all lines that have through services contain at least one route beyond Tokyo.

==Station list==
* Express trains stop at stations marked with a circle (●), while local trains make all stops.
* Express trains run between Motoyawata Station and [[Hashimoto Station (Kanagawa)|Hashimoto Station]] on the [[Keiō Sagamihara Line]] via the Keio Main Line and Keio New Line. Express trains only run during peak hours; westbound in the mornings and eastbound in the evenings.
* On weekends and holidays, two trains run through to [[Takaosanguchi Station]] on the [[Keiō Takao Line]] and one runs through to [[Tama-Dōbutsukōen Station]] on the [[Keiō Dōbutsuen Line]].
