The {{Nihongo|'''Tokyo Metro Fukutoshin Line'''|東京メトロ副都心線|Tōkyō Metoro Fukutoshin-sen}}, formally the {{Nihongo|'''No. 13 Fukutoshin Line'''|13号線副都心線|Jūsangō-sen Fukutoshin-sen}}, is a {{convert|20.2|km|adj=on|sp=us}} subway line operated by [[Tokyo Metro]] in west-central [[Tokyo]] and [[Wako, Saitama]], Japan. The newest line in the Tokyo subway network, it opened in stages between 1994 and 2008.<ref>{{cite web |url=http://mdn.mainichi.jp/national/archive/news/2008/06/13/20080613p2a00m0na012000c.html |title=毎日ｊｐ(毎日新聞) |access-date=2008-06-14 |url-status=dead |archive-url=https://archive.today/20120710182830/http://mdn.mainichi.jp/national/archive/news/2008/06/13/20080613p2a00m0na012000c.html |archive-date=2012-07-10 }}</ref> On average, the Fukutoshin Line carried 362,654 passengers daily in 2017,<ref name="ridership"/> the lowest of all Tokyo Metro lines and roughly one third of its sister [[Tokyo Metro Yūrakuchō Line]] (1,124,478).

==Overview==
The Fukutoshin Line is the deepest metro line in Tokyo, with an average depth of {{convert|27|m|sp=us}}.<ref name="yahoo">{{cite web|url=https://blogs.yahoo.co.jp/tucasa_kenko/53685223.html|title=東京メトロ・副都心線 １４日開業|website=ＭＯＮＯ好き親父の一輪車乗りの独り言|access-date=3 March 2019}}</ref> At [[Shinjuku-sanchōme Station]], the line passes under the [[Tokyo Metro Marunouchi Line|Marunouchi]] and above the [[Toei Shinjuku Line|Shinjuku]] lines at a depth of {{convert|15|m|sp=us}}, with a gap of only {{convert|11|cm|sp=us}} to the Shinjuku Line tunnel.<ref name="yahoo"/> The deepest section is at the immediately adjacent [[Higashi-Shinjuku Station]], where the line goes down to {{convert|35|m|sp=us}}, partly due to an underground space reservation for a possible future extension of the [[Jōetsu Shinkansen]] to Shinjuku.<ref name="yahoo"/>

It is the second Tokyo Metro line to feature express services, after the [[Tokyo Metro Tōzai Line|Tōzai Line]]; however, unlike the Tōzai Line (where rapid services are only offered on the {{STN|Tōyōchō|x}} – {{STN|Nishi-Funabashi|x}} section), the Fukutoshin Line offers express services throughout the line, a first for Tokyo Metro. Express trains pass local trains at Higashi-Shinjuku, where additional tracks are installed for this purpose. Local trains stop at all stations.

When first opened, the line operated [[Through train|through services]] to [[Kawagoeshi Station]] on the [[Tobu Tojo Line]] and [[Hannō Station]] on the [[Seibu Ikebukuro Line]]. From 16 March 2013, the [[Tōkyū Tōyoko Line]] moved to share the line's Shibuya terminus, and since then through services have operated onto the [[Minatomirai Line]] via the Tōyoko Line, terminating at [[Motomachi-Chūkagai Station]] in [[Yokohama]].<ref name="tobu20120724">{{cite web |url= http://www.tobu.co.jp/file/pdf/9e67f9298f0c2a004a27615807b6cc25/120724.pdf?date=20120723185709|script-title=ja:東武東上線がより便利に！ 自由が丘、横浜、元町・中華街方面とつながります！|trans-title= The Tojo Tobu Line will be even more convenient!

Since the opening of the section between Ikebukuro and Shibuya station, the Fukutoshin Line operates as a [[one-man operation]] subway line between [[Kotake-Mukaihara Station]] and [[Shibuya Station]] where chest-high [[platform edge doors]] are installed on the station platforms to aid the drivers.<ref>[http://search-tokyometro.dga.jp/?go=http%3A%2F%2Fwww.tokyometro.jp%2Fnews%2F2008%2F2008-25.html%26f%3Dr&rid=1272384&ref=http%3A%2F%2Fwww.tokyometro.jp%2Fnews%2F2009%2F2009-14.html&PHPSESSID=09f5379829a808a353325d56e552d97d 14 May 2008. Accessed 1 August 2013.]</ref> From 28 March 2015, one-man operation was extended from Kotake-Mukaihara to [[Wakōshi Station|Wakōshi station]],<ref>{{Cite web |date=2015-03-10 |title=有楽町線 |lang=ja |url=https://www.tokyometro.jp/news/images_h/metroNews20150310_23.pdf |access-date=2023-05-21 |archive-url=https://web.archive.org/web/20200309144835/https://www.tokyometro.jp/news/images_h/metroNews20150310_23.pdf |archive-date=2020-03-09}}</ref> making this the third Tokyo Metro line to fully operate as one-man operation, following the [[Tokyo Metro Namboku Line|Namboku Line]] and Marunouchi Line.

Like most Tokyo Metro lines, the first carriage of the Fukutoshin Line is designated a "women-only car" before and during the morning rush hour. During these hours only women, children of [[Elementary schools in Japan|elementary school]] age or younger and physically [[disabled]] passengers (and their [[caregiver|carers]]) may board the first carriage.<ref>{{cite web|url=https://www.tokyometro.jp/safety/attention/women/|title=女性専用車｜東京メトロ|website=www.TokyoMetro.jp|access-date=3 March 2019}}</ref>

==History==
[[File:Construction of Kita-Sando Station at April 6th 2006.jpg|thumb|Construction at Kitasandō Station, 2006]]
''Fukutoshin'' is Japanese for "secondary city center", and the Fukutoshin Line connects three of Tokyo's secondary city centers: [[Ikebukuro]], [[Shinjuku]] and [[Shibuya, Tokyo|Shibuya]]. Prior to its opening, only [[East Japan Railway Company|JR East]] had rail service between the three (on the [[Yamanote Line]], the [[Saikyō Line]] and the [[Shōnan-Shinjuku Line]]). The new line was conceived to relieve congestion along this busy corridor, and to provide convenient through service between the northwest, the southwest and the central part of Tokyo served by the Yamanote Line.

The line was initially planned in 1972 as a run from [[Shiki Station (Saitama)|Shiki]] to Shinjuku, with the possibility of further extension to Shibuya, {{STN|Shinagawa|x}} and [[Haneda Airport]]. In 1985, a second Ministry of Transportation committee proposed that the line terminate at Shibuya. Part of the northern end of the original plan line became unnecessary following improvements to the [[Tobu Tojo Line]] and the beginning of through service from the [[Tokyo Metro Yurakucho Line|Yurakucho Line]].

The original plan for the Fukutoshin Line only contained fifteen stations, however in May 1999 a plan for an additional station "Shin-Sendagaya" (later renamed {{STN|Kitasandō|x}}) between {{STN|Shinjuku-sanchōme|x}} and {{STN|Meiji-Jingūmae|x}} was included due to an increase in demand from the area.<ref>[https://web.archive.org/web/19991112084526/http://www.tokyometro.go.jp/news/99-12.html より便利な地下鉄を目指して] 20 May 1999. Accessed 1 August 2013.</ref>

A {{convert|3.2|km|abbr=on}} segment from [[Kotake-Mukaihara]] to [[Ikebukuro]], running parallel to the [[Tokyo Metro Yurakucho Line|Yurakucho Line]] on separate tracks began operation in 1994. This segment was initially known as the {{Nihongo|Yūrakuchō New Line|有楽町新線|Yūrakuchō Shin-sen}}, and was operated with no intermediate stops.

The newest segment connecting the districts of [[Shinjuku, Tokyo|Shinjuku]] and [[Shibuya, Tokyo|Shibuya]] via {{STN|Zōshigaya|x}}, {{STN|Shinjuku-sanchōme|x}}, and {{STN|Meiji-Jingūmae|x}} (‘Harajuku’) opened for service on 14 June 2008, officially completing the Fukutoshin Line.<ref>{{Cite web |date=27 March 2007 |title=副都心線・有楽町線のダイヤが決定！ |trans-title=Fukutoshin Line and Yurakucho Line timetables have been decided! |url=http://www.tokyometro.jp/news/2008/2008-17.html |archive-url=https://web.archive.org/web/20170718015046/http://www.tokyometro.jp/news/2008/2008-17.html |archive-date=18 July 2017 |access-date=31 January 2024 |website=tokyometro.jp |language=ja}}</ref> Service to the {{STN|Senkawa|x}} and {{STN|Kanamechō|x}} stations, which had been bypassed by the Yūrakuchō New Line, also started on the same day.

Technical problems resulted in delays of up to 30 minutes during the Fukutoshin Line's first few days of operation.<ref>http://mdn.mainichi.jp/national/archive/news/2008/06/17/20080617p2a00m0na006000c.html{{Dead link|date=July 2018 |bot=InternetArchiveBot |fix-attempted=no }}</ref>

On 6 March 2010, express services began stopping at {{STN|Meiji-Jingūmae|x}} on weekends and holidays.<ref>[http://www.tokyometro.jp/news/2010/2010-06.html 3月6日（土）有楽町線・副都心線のダイヤ改正] 3 February 2010. Accessed 8 March 2010.</ref>

From 10 September 2012, 10-car 5050-4000 series sets entered revenue service on the Tokyo Metro Fukutoshin Line, with inter-running through to the [[Seibu Ikebukuro Line]] (via [[Seibu Yurakucho Line]]) and [[Tobu Tojo Line]].<ref name="rmnews20120910">{{cite web |url= http://rail.hobidas.com/rmn/archives/2012/09/5050_2.html|script-title=ja:東急5050系が西武鉄道池袋線で営業運転開始|trans-title= Tokyu 5050 series enters service on the Seibu Ikebukuro Line |date= 10 September 2012|work= RM News|publisher= Neko Publishing|location= Japan|language= ja|access-date= 10 September 2012}}</ref>

From the revised timetable effective 18 March 2023, through services to and from the [[Sōtetsu Main Line|Sotetsu Line]] courtesy of the [[Tōkyū Shin-yokohama Line|Tokyu]] and [[Sōtetsu Shin-yokohama Line|Sotetsu Shin-Yokohama Line]] began operation.<ref>{{Cite web |date=27 January 2022 |title=～神奈川県央地域及び横浜市西部から東京・埼玉に至る広域的な鉄道ネットワークの形成～ |trans-title=-Formation of a wide-area railway network from central Kanagawa Prefecture and western Yokohama to Tokyo and Saitama- |url=https://www.tokyometro.jp/news/images_h/metroNews220127_g01_1.pdf |archive-url=https://web.archive.org/web/20220127092346/https://www.tokyometro.jp/news/images_h/metroNews220127_g01_1.pdf |archive-date=27 January 2022 |access-date=22 March 2023 |website=tokyometro.jp}}</ref> This operation sees most express services continuing as far south as [[Shōnandai Station]] on the [[Sōtetsu Izumino Line|Sotetsu Izumino Line]] by way of the [[Tōyoko Line|Toyoko Line]].
