The {{nihongo|'''Toei Subway'''|都営地下鉄|Toei chikatetsu|{{lit|metropolis-operated subway}}<ref>{{cite web |last1=日本国語大辞典,デジタル大辞泉 |first1=精選版 |title=都営(とえい)とは？ 意味や使い方 |url=https://kotobank.jp/word/%E9%83%BD%E5%96%B6-581767 |website=コトバンク |language=ja}}</ref>}} is one of two subway systems in [[Tokyo]], Japan, the other being the [[Tokyo Metro]]. The Toei Subway lines were originally licensed to the Teito Rapid Transit Authority (the predecessor of Tokyo Metro) but were constructed by the [[Tokyo Metropolitan Government]] following transfers of the licenses for each line. The subway has run at a financial loss for most of its history due to high construction expenses, particularly for the [[Toei Ōedo Line |Oedo Line]]. However, it reported its first net profit of ¥3.13bn in FY2006. The Toei Subway is operated by the [[Tokyo Metropolitan Bureau of Transportation]].

Tokyo Metro and Toei trains form completely separate networks. While users of prepaid rail passes can freely interchange between the two networks, 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. The sole exceptions are on the segment of the Toei Mita Line between Meguro and Shirokane-Takanawa, where the platforms are shared with the [[Tokyo Metro Namboku Line]], and at [[Kudanshita Station|Kudanshita]] on the Shinjuku Line, where the platform is shared with the [[Tokyo Metro Hanzomon Line]]. At these stations, it is possible to change between the networks without passing through a ticket gate.

== Branding ==
Apart from its own logo, a stylized [[ginkgo]] leaf used as [[symbols of Tokyo#Metropolitan symbol|the symbol of the Tokyo Metropolis]], Toei Subway shares a design language in common with Tokyo Metro. Lines are indicated by a letter in [[Futura (typeface)|Futura Bold]] on a white background inside a roundel in the line color, with signs indicating stations adding the station number as well. Line colors and letter-designations are complementary with Tokyo Metro's, with none overlapping (e.g., the Mita Line's letter-designation is “I”, rather than “M”, which is used by the [[Tokyo Metro Marunouchi Line]]). Informational signage is also designed identically, with platform-level station placards differing only in the placement of the bands in the line color: Toei Subway has two thin bands at the top and bottom, while Tokyo Metro has one wider band at the bottom (or, in the case of long, narrow placards, in a continuous band extending to the left and right along the wall itself).

== Lines ==
The Toei Subway is made up of four lines operating on {{convert|109.0|km|mi|sp=us}} of route.<ref name="Toei-Subway">{{cite web |url=http://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 |date=April 1, 2015 |access-date=2016-01-17}}</ref>

Two of the lines have different colors for their station signs: Asakusa (Vermilion {{TSLS2|A}}) and Shinjuku (Lime {{TSLS2|S}}). The Ōedo Line formerly had a darker magenta (<span style="color:#8B008B; background:#8B008B;">O</span>) as its designated color.

=== Through services to other lines ===
The different gauges of the Toei lines arose in part due to the need to accommodate through services with private suburban railway lines. Through services currently in regular operation include:

According to the company, an average of 2.34 million people used the company's four subway routes each day in 2008.  The company made a profit of ¥12.2 billion in 2009.<ref>Martin, Alex, "[http://search.japantimes.co.jp/cgi-bin/nn20100803i1.html Ubiquitous Tokyo subways moving the daily masses]", ''[[Japan Times]]'', August 3, 2010, p. 3.</ref>

== Stations ==
{{see also|List of Toei Subway stations}}
There are a total of 99 unique stations (i.e., counting stations served by multiple lines only once) on the Toei Subway network, or 106 total stations if each station on each line counts as one station.<ref name="Toei-Subway" /> Almost all stations are located within the 23 special wards, with many located in areas not served by the complementary [[Tokyo Metro]] network.
