The {{Nihongo|'''Tokyo Metro Tozai Line'''|東京メトロ東西線|Tōkyō Metoro Tōzai-sen}} is a [[rapid transit]] line in [[Tokyo]] and [[Chiba Prefecture]], Japan, owned and operated by [[Tokyo Metro]]. Its name translates to "''East-West Line"''. The line runs between [[Nakano Station (Tokyo)|Nakano]] in [[Nakano, Tokyo|Nakano-ku, Tokyo]] and [[Nishi-Funabashi Station|Nishi-Funabashi]] in [[Funabashi, Chiba|Funabashi, Chiba Prefecture]]. The Tōzai Line was referred to as Line 5 during the planning stages; the seldom-used official name is {{Nihongo|Line 5 Tōzai Line|5号線東西線|Go-gō-sen Tōzai-sen}}. The line carries an average of 1,642,378 passengers daily (2017), making it the busiest line on the Tokyo Metro network.<ref name="train media" /> On maps, diagrams and signboards, the Tōzai Line is shown using the color "sky blue" and its stations are given numbers using the letter "T".

==Overview==
The line runs through central [[Tokyo]] from east to west via [[Takadanobaba Station|Takadanobaba]], [[Waseda Station (Tokyo Metro)|Waseda]], [[Ōtemachi Station (Tokyo)|Ōtemachi]], [[Nihombashi Station|Nihombashi]], [[Kiba Station|Kiba]] and [[Urayasu Station (Chiba)|Urayasu]]. It was opened as a bypass route for the [[Chūō Line (Rapid)|Chuo Rapid Line]] and the [[Sōbu Main Line|Sobu Line]], which were heavily congested at the time. It is the only [[Tokyo Metro]] line to extend into [[Chiba Prefecture]] (although the [[Toei Shinjuku Line|Shinjuku Line]] operated by [[Toei Subway|Toei]] also extends into Chiba Prefecture.) It also runs above-ground for {{Convert|14|km|abbr=on}} from {{STN|Minami-Sunamachi|x}} to {{STN|Nishi-Funabashi|x}}, nearly half of the line and longer than any other railway line in the [[Tokyo subway]] network.

The Tōzai Line features [[through train|through services]] at both ends of the line. Trains run onto the [[East Japan Railway Company|JR East]] [[Chūō-Sōbu Line]] for {{STN|Mitaka|x}} at the western (Nakano) end, and onto either the Chūō-Sōbu Line for {{STN|Tsudanuma|x}} or the [[Tōyō Rapid Railway Line]] for {{STN|Tōyō-Katsutadai|x}} at the eastern (Nishi-Funabashi) end.

According to the [[Tokyo Metropolitan Bureau of Transportation]] in 2018, the Tokyo Metro Tōzai Line continues to be most crowded subway line in [[Tokyo]], and the most crowded train line in all of Japan, with its peak running at 199% capacity{{Ref label|notes1|a|}} between {{STN|Kiba|x}} and {{STN|Monzen-Nakachō|x}} 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><ref>{{Cite web|url=https://www.mlit.go.jp/common/001299797.pdf|title=Amount and a congestion rate of passengers who got on|archive-url=https://web.archive.org/web/20190920002726/https://www.mlit.go.jp/common/001299797.pdf|archive-date=2019-09-20}}</ref> [[Women-only passenger car|Women-only cars]] were introduced on the line for use during morning rush hour on November 20, 2006.

During the COVID-19 pandemic, peak ridership dropped from a rate of 199% in 2019 to 123% in 2020.

==History==
{{More citations needed section|date=May 2022}}
The Tōzai Line was planned by a review committee of the then Ministry of Transportation in 1962 and numbered '''Line 5'''. Its name literally means "East-West Line", and it was primarily planned to relieve traffic on the busy [[Sōbu Main Line]] as well as provide a straight crosstown connection through north-central Tokyo. Although this corridor is also served by the [[Tokyo Metropolitan Bureau of Transportation]] (Toei) [[Toei Shinjuku Line|Shinjuku Line]] and JR [[Keiyō Line]], the Tōzai Line continues to operate beyond capacity due to its accessibility to other lines, as well as to growing [[Condominium (living space)|condominium]] developments in eastern Tokyo.

The {{STN|Takadanobaba|x}} to {{STN|Kudanshita|x}} section opened in 1964,<ref>{{Cite web |title=History |url=https://www.tokyometro.jp/lang_en/corporate/profile/history/index.html |archive-url=https://web.archive.org/web/20230605063443/https://www.tokyometro.jp/lang_en/corporate/profile/history/index.html |archive-date=2023-06-05 |access-date=2024-07-13 |website=tokyometro.jp}}</ref> and the remainder opened in stages until its completion in 1969. Through service with the then [[Japanese National Railways]] (today part of the [[JR Group]]) – a first for a Tokyo subway line – began in 1969 connecting the Chūō and Sōbu lines. This is a rare situation in Tokyo, as the only other subway line with through services onto JR lines is the [[Tokyo Metro Chiyoda Line|Chiyoda Line]].

The [[Tōyō Rapid Railway Line]], effectively an eastward extension of the line, opened in 1996. It nevertheless remains a private entity to which the Tōzai lines offers through services.

==Services==
The Tōzai Line was the first Tokyo Metro line on which express services run: two types of rapid trains skip some stations east of Toyocho. The [[Tokyo Metro Fukutoshin Line]] began services on June 14, 2008, and also features express services.

Through services to {{STN|Mitaka|x}} via the JR East Chūō Line and {{STN|Tōyō-Katsutadai|x}} via the Tōyō Rapid Railway run all day. Outside of rush hours, only local trains run through to the Chūō Line and only rapid trains run through to the Tōyō Rapid Railway. During the morning and evening peak periods, through services run to {{STN|Tsudanuma|x}} via the JR East Sōbu Line.

== Station list ==
*Local trains stop at every station. Rapid trains stop at stations marked "●" and do not stop at those marked "｜". Some weekday westbound trains do not stop at stations marked "↑".
