The '''Tokyo Metro''' ({{langx|ja|東京メトロ|Tōkyō Metoro}}) is a major [[rapid transit system]] in [[Tokyo]], Japan, operated by the [[#Organization|Tokyo Metro Co.]] With an average daily ridership of 6.52 million passengers (as of 2023), the Tokyo Metro is the larger of the [[Tokyo subway|two subway operators]] in the city, the other being the [[Toei Subway]], with 2.85 million average daily rides.<ref name=TM2012/><ref name="Toei-Subway">{{cite web |url=https://www.kotsu.metro.tokyo.jp/information/service/subway.html |script-title=ja:東京都交通局ホーム - 経営情報 - 交通局の概要 - 都営地下鉄 |publisher=東京都交通局 [Tokyo Metropolitan Bureau of Transportation] |language=ja |trans-title=Tokyo Metropolitan Bureau of Transportation Home - Management Information - Overview of the Department of Transportation - Toei Subway |access-date=2015-11-24}}</ref>

==Organization==
[[File:TRTA logo.svg|thumb|The old TRTA logo, a stylized [[roundel]] in the shape of an "S" was introduced in 1953, adopted as TRTA's corporate logo in 1960 and used until 2004.]]
[[File:Tokyo Metro Office Building.jpg|thumb|right|Head office of Tokyo Metro near [[Ueno Station]], one of the first stations of the network]]
Tokyo Metro is operated by {{Nihongo|the '''Tokyo Metro Co., Ltd.'''|東京地下鉄株式会社|Tōkyō Chikatetsu kabushiki-gaisha}}, a [[joint-stock company]] jointly owned by the [[Government of Japan]] and the [[Tokyo Metropolitan Government]].

The company, founded as a part of then-Prime Minister [[Junichiro Koizumi]]'s policy of converting [[statutory corporation]]s into [[Joint-stock company|joint-stock companies]], replaced the {{Nihongo|'''Teito Rapid Transit Authority'''|[[w:ja:帝都高速度交通営団|帝都高速度交通営団]]|Teito Kōsokudo Kōtsū Eidan|lit. "Imperial Capital{{efn|{{nihongo||帝都|Teito}} means the {{nihongo|"capital of the [[Empire of Japan]]"|大日本'''帝'''国の首'''都'''|Dai Nippon '''Tei'''koku no shu'''to'''}}, that is, Tokyo}} Highspeed Transportation Management Foundation"}}, commonly known as Eidan or TRTA, on April 1, 2004.<ref>{{Cite web |date=2006-07-08 |title=「営団地下鉄」から「東京メトロ」へ |trans-title=From "Teito Rapid Transit Authority" to "Tokyo Metro" |url=https://www.tokyometro.jp/news/s2004/2004-06.html |url-status=dead |archive-url=https://web.archive.org/web/20120516041232/http://www.tokyometro.jp/news/s2004/2004-06.html |archive-date=16 May 2012 |access-date=29 May 2022 |website=Tokyo Metro Online}}</ref> TRTA was administered by the [[Ministry of Land, Infrastructure and Transport (Japan)|Ministry of Land, Infrastructure and Transport]], and jointly funded by the national and metropolitan governments. It was formed in 1941 as a part-nationalization of the Tokyo Underground Railway and Tokyo Rapid Railway (now both form the [[Tokyo Metro Ginza Line]]), although its oldest lines date back to 1927 with the opening of the Tokyo Underground Railway the same year. Upon its establishment, the TRTA's legal form was a {{nihongo|"management foundation"|経営財団|keiei zaidan|abbreviated to and hence {{nihongo||[[w:ja:営団|営団]]|eidan}}}}, a form of entity established by the government of the wartime cabinet of the [[Empire of Japan]] with both public and private sector investments. Private sector investments to the TRTA were prohibited in 1951 when it was converted into an ordinary statutory corporation. In 2024, the company made its [[initial public offering]], raising $2.3 billion in what became Japan's biggest IPO since 2018.<ref name=":0">{{cite web | url=https://www.france24.com/en/live-news/20241023-tokyo-metro-asia-s-oldest-subway-goes-public | title=Tokyo Metro: Asia's oldest subway goes public |date=23 October 2024 |work=France 24 }}</ref>

The other major subway operator is [[Tokyo Metropolitan Bureau of Transportation]] ([[Toei Subway]]) which is owned solely by the government of Tokyo. Tokyo Metro and Toei trains form completely separate networks, although [[Tokyo Metro Namboku Line]] and [[Toei Mita Line]] share the same track between [[Meguro Station]] and [[Shirokane-takanawa Station]]. Users of prepaid rail passes and [[Suica]]/[[Pasmo]] [[smart card]]s can freely interchange between the two networks (as well as other rail companies in the area), but fares are assessed separately for legs on each of these systems and regular ticket holders must purchase a second ticket, or a special transfer ticket, to change from a Toei line to a Tokyo Metro line and vice versa. Though, most Tokyo Metro (and Toei) line offer through service to lines outside of central Tokyo run by other carriers, and this can somewhat complicate the ticketing.

Much effort has been made to make the system accessible to non-Japanese speaking users:

* Many train stops are announced in both English and Japanese. Announcements also provide connecting line information.
* [[Ticket machine]]s can switch between English and Japanese user interfaces.
* Train stations are signposted in English and Japanese (in [[kanji]] and [[hiragana]]). There are also numerous signs in Chinese (in [[Simplified Chinese character|simplified characters]]) and Korean.
* Train stations are now also [[station numbering|consecutively numbered on each color-coded line]], allowing even non-English speakers to be able to commute without necessarily knowing the name of the station. For example, [[Shinjuku Station]] on the [[Tokyo Metro Marunouchi Line|Marunouchi Line]] is also signposted as M-08 with a red colored circle surrounding it; even if a commuter could not read the English or Japanese station names on signs or maps, they could simply look for the red line and then find the appropriately numbered station on said line. In addition, some trains have interior LCD displays which display station names in Japanese, English, Chinese, and Korean.

Many stations are also designed to help blind people as railings often have [[Braille]] at their base, and raised yellow rubber guide strips are used on flooring throughout the network.

Tokyo Metro stations began accepting contactless ([[RFID]]) [[Pasmo]] stored value cards in March 2007 to pay fares, and the JR East [[Suica]] system is also universally accepted. Both these passes also can be used on surrounding rail systems throughout the area and many rail lines in other areas of Japan. Due to the complexity of the fare systems in Japan, most riders converted to these cards very quickly even though there is an additional charge to issue it.

The Tokyo Metro is punctual{{cn|date=June 2025}} and has regular trains arriving 3 to 6 minutes apart most of the day and night. However, it does not run 24 hours a day. While through service with other companies complicates this somewhat, the last train generally starts at midnight and completes its service by 00:45 to 01:00, and the first train generally starts at 05:00.

Tokyo Metro also owns a number of commercial developments which mostly consist of shopping developments at major stations. It also owns the [[:ja:地下鉄博物館|Subway Museum]] near [[Kasai Station]] on the [[Tokyo Metro Tōzai Line]] which opened on July 12, 1986, and features a few retired trains which once operated on the Ginza and Marunouchi Lines as well as a maintenance vehicle and some [[train simulator]]s.

In 2024, Tokyo Metro was listed on the [[Tokyo Stock Exchange]], debuting as the exchange's largest IPO in six years and with a market capitalization of roughly 1 trillion yen.<ref name=":0" /> The [[Government of Japan]] and the [[Tokyo Metropolitan Government]] each sold half of their shares, with the former using the proceeds to repay bonds funding reconstruction after the [[2011 Tōhoku earthquake and tsunami]].<ref>{{cite web|title=Tokyo Metro surges 47.3% on debut in Japan's biggest IPO in 6 years|date=2024-10-30|url=https://english.kyodonews.net/news/2024/10/01f18868ea16-tokyo-metro-shares-debut-in-japans-biggest-ipo-in-6-yrs.html|work=Kyodo news}}</ref><ref>{{cite web|title=Tokyo Metro shares surge 45% on debut after Japan’s largest IPO in six years|url=https://www.cnbc.com/2024/10/23/tokyo-metro-shares-gain-40percent-on-debut-after-japans-largest-ipo-in-six-years-.html|work=CNBC|date=2024-10-30}}</ref>

=== Overseas affiliates ===
In 2017, Tokyo Metro opened its affiliate in [[Hanoi]], [[Vietnam]], as part of preparations to be the service operator of [[Hanoi Metro]].<ref>[http://vneconomictimes.com/article/business/vietnam-tokyo-metro-set-up-to-run-hanoi-s-urban-railway Vietnam Tokyo Metro set up to run Hanoi's urban railway]</ref><ref>[https://www.tokyometro.jp/lang_en/corporate/profile/history/index.html History of Tokyo Metro]</ref> The Hanoi Metro opened in 2021.<ref>{{cite web |last=Burroughs |first=David |date=9 November 2021 |title=Hanoi opens Vietnam's first metro line |url=https://www.railjournal.com/passenger/metros/hanoi-opens-vietnams-first-metro-line/ |website=[[International Railway Journal]]}}</ref>

In November 2024, [[GTS Rail Operations]] (a consortium comprising [[Go-Ahead Group]], Tokyo Metro and [[Sumitomo Corporation]]) was chosen from four bidders to operate the [[Elizabeth line]] in London, England, for seven years from May 2025 with an option to extend for two years.<ref>{{Cite news |last=Simpson |first=Jack |date=2024-11-20 |title=Tokyo Metro wins contract to operate London’s Elizabeth line |url=https://www.theguardian.com/uk-news/2024/nov/20/tokyo-metro-wins-contract-operate-london-elizabeth-line |access-date=2024-11-20 |work=[[The Guardian]]|language=en-GB |issn=0261-3077}}</ref><ref>New operator announced for Elizabeth Line ''[[Rail Express]]'' issue 344 January 2025 page 10</ref>

==Future expansion==
Tokyo Metro indicated in its public share offering that it would cease line construction once the [[Tokyo Metro Fukutoshin Line|Fukutoshin Line]] was completed.{{Citation needed|date=October 2024}} That line was completed in March 2013 with the opening of the connection with the [[Tōkyū Tōyoko Line]] at [[Shibuya|Shibuya Station]], allowing through service as far as [[Motomachi-Chūkagai Station]] in [[Yokohama]]. There are several lines such as the [[Tokyo Metro Hanzōmon Line|Hanzōmon Line]] that still have extensions in their official plans, and in the past, these plans have tended to happen, though often over several decades.

In March 2022, Tokyo Metro received permission to add two new extensions to the network. Under these plans, the [[Tokyo Metro Yūrakuchō Line|Yūrakuchō Line]] would receive a new branch from [[Toyosu Station]] to [[Sumiyoshi Station (Tokyo)|Sumiyoshi Station]] with three new stops (including one at [[Toyocho Station]] on the [[Tokyo Metro Tozai Line|Tōzai Line]]) to better serve the [[Toyosu]] urban development zone, and the [[Tokyo Metro Namboku Line|Namboku Line]] would receive an extension from [[Shirokane-Takanawa Station]] to [[Shinagawa Station]], where it would connect with the [[Tokaido Shinkansen]] and the under-construction [[Chūō Shinkansen]] in addition to serving the surrounding business district. Both extensions are expected to open in the 2030s.<ref>{{cite web|date=2024-10-30 |title= Tokyo Metro Receives Approval for Yurakucho and Namboku Line Extensions| work=International Railway Journal|url=https://www.railjournal.com/passenger/metros/tokyo-metro-receives-approval-for-yurakucho-and-namboku-line-extensions/}}</ref><ref>{{cite web|date=2024-10-30 |title=Tokyo to Build New Waterfront Metro Line|work=International Railway Journal|url=https://www.railjournal.com/passenger/metros/tokyo-to-build-new-waterfront-metro-line/}}</ref><ref>{{cite web | date=2024-10-30 |title=Tokyo Metro eyes extending 2 subway lines to ease congestion

==Fares==
[[Pasmo]] and [[Suica]] are accepted on the Tokyo Metro, as well as on railway stations operated by other companies. Transfers between Tokyo Metro subway lines and [[Tokyo Metropolitan Bureau of Transportation|Toei Subway]] lines are usually not free, but a discount is given when using the Pasmo or Suica cards to transfer between lines.

==Traffic==
According to the company, an average of 6.33 million people used the company's nine subway routes each day in 2009. The company made a profit of ¥63.5 billion in 2009.<ref>{{cite news |author=Martin, Alex |url=https://search.japantimes.co.jp/cgi-bin/nn20100803i1.html |title=Ubiquitous Tokyo subways moving the daily masses |newspaper=[[The Japan Times]] |date=August 3, 2010 |page=3}}</ref>

==Lines==
Altogether, the Tokyo Metro is made up of nine lines operating on {{convert|195.1|km|mi|sp=us}} of route.<ref name="lines">{{cite web |url=https://www.tokyometro.jp/en/corporate/enterprise/transportation/conditions/index.html |title=Business Contents - Transportation Services - Business Situation |publisher=Tokyo Metro Co., Ltd. |access-date=2014-06-07}}</ref>

==Overcrowding==
[[File:TokyoMetroSignReservedForWomen.jpg|thumb|A sign on the [[Hibiya Line]] denoting that cars stopping in this area are for women only during morning peak hours]]{{Unreferenced section|date=May 2022}}
As is common with [[rail transport]] in Tokyo, Tokyo Metro trains are severely crowded during peak periods. During the morning peak period, platform attendants ([[oshiya]]) are sometimes needed to push riders and their belongings into train cars so that the doors can close. On some Tokyo Metro lines, the first or last car of a train is reserved for women during peak hours.
