:Toei Subway

Apart from its own logo, a stylized ginkgo leaf used as 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 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).

The Toei Subway is made up of four lines operating on {{convert|109.0|km|mi|sp=us}} of route.{{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}}

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 (O) as its designated color.

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:

• Mita Line shares tracks of the section from Meguro to Shirokane-takanawa with Tokyo Metro Namboku Line, {{convert|2.3|km|mi}}.

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.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.

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. Almost all stations are located within the 23 special wards, with many located in areas not served by the complementary Tokyo Metro network.
