TheFukutoshin Line (副都心線,Fukutoshin-sen), formally theNo. 13 Fukutoshin Line (13号線副都心線,Jū-san-gō-sen Fukutoshin-sen), is a 20.2-kilometer (12.6 mi) subway line operated byTokyo Metro in west-centralTokyo andWako, Saitama, Japan.

The newest line in the Tokyo subway network, it opened in stages between 1994 and 2008.^[2] On average, the Fukutoshin Line carried 362,654 passengers daily in 2017,^[1] the lowest of all Tokyo Metro lines and roughly one third of its sisterTokyo Metro Yūrakuchō Line (1,124,478).

Fukutoshin is Japanese for "secondary city center", and the Fukutoshin Line connects three of Tokyo's secondary city centers:Ikebukuro,Shinjuku andShibuya. Prior to its opening, onlyJR East had rail service between the three (on theYamanote Line, theSaikyō Line and theShōnan-Shinjuku Line).

The Fukutoshin Line is the deepest metro line in Tokyo, with an average depth of 27 meters (89 ft).^[3] AtShinjuku-sanchōme Station, the line passes under theMarunouchi and above theShinjuku lines at a depth of 15 meters (49 ft), with a gap of only 11 centimeters (4.3 in) to the Shinjuku Line tunnel.^[3] The deepest section is at the immediately adjacentHigashi-Shinjuku Station, where the line goes down to 35 meters (115 ft), partly due to an underground space reservation for a possible future extension of theJōetsu Shinkansen to Shinjuku.^[3]

It is the second Tokyo Metro line to feature express services, after theTōzai Line; however, unlike the Tōzai Line (where rapid services are only offered on theTōyōchō –Nishi-Funabashi 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 operatedthrough services toKawagoeshi Station on theTobu Tojo Line andHannō Station on theSeibu Ikebukuro Line. From 16 March 2013, theTōkyū Tōyoko Line moved to share the line's Shibuya terminus, and since then through services have operated onto theMinatomirai Line via the Tōyoko Line, terminating atMotomachi-Chūkagai Station inYokohama.^[4] This is a rare instance of a Tokyo Metro train operating on four companies' tracks.^[5]

Since the opening of the section between Ikebukuro and Shibuya station, the Fukutoshin Line operates as aone-man operation subway line betweenKotake-Mukaihara Station andShibuya Station where chest-highplatform edge doors are installed on the station platforms to aid the drivers.^[6] From 28 March 2015, one-man operation was extended from Kotake-Mukaihara toWakōshi station,^[7] making this the third Tokyo Metro line to fully operate as one-man operation, following theNamboku 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 ofelementary school age or younger and physicallydisabled passengers (and theircarers) may board the first carriage.^[8]

The line was initially planned in 1972 as Line 13 running fromShiki to Shinjuku, with the possibility of further extension to Shibuya,Shinagawa andHaneda Airport. 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.

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 theTobu Tojo Line and the beginning of through service from theYurakucho 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 renamedKitasandō) betweenShinjuku-sanchōme andMeiji-Jingūmae was included due to an increase in demand from the area.^[9]

A 3.2 km (2.0 mi) segment fromKotake-Mukaihara toIkebukuro, running parallel to theYurakucho Line on separate tracks began operation in 1994. This segment was initially known as the Yūrakuchō New Line (有楽町新線,Yūrakuchō Shin-sen), and was operated with no intermediate stops.

The newest segment connecting the districts ofShinjuku andShibuya viaZōshigaya,Shinjuku-sanchōme, andMeiji-Jingūmae (‘Harajuku’) opened for service on 14 June 2008, officially completing the Fukutoshin Line.^[10] Service to theSenkawa andKanamechō 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.^[11]

On 6 March 2010, express services began stopping atMeiji-Jingūmae on weekends and holidays.^[12]

From 10 September 2012, 10-car 5050-4000 series sets entered revenue service on the Tokyo Metro Fukutoshin Line, with inter-running through to theSeibu Ikebukuro Line (viaSeibu Yurakucho Line) andTobu Tojo Line.^[13]

From the revised timetable effective 18 March 2023, through services to and from theSotetsu Line courtesy of theTokyu andSotetsu Shin-Yokohama Line began operation.^[14] This operation sees most express services continuing as far south asShōnandai Station on theSotetsu Izumino Line by way of theToyoko Line.
