Toei Subway

Subway system in Greater Tokyo, Japan

The Toei Subway (Japanese: 都営地下鉄; lit. 'metropolis-operated subway') is a major rapid transit system in Tokyo, Japan, operated by the Tokyo Metropolitan Bureau of Transportation under the Tokyo Metropolitan Government Ordinance on Underground High-Speed Trains. 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 in 1958. It is the one of Tokyo's two subway operators, with an average daily ridership of 2.85 million; the other operator, the Tokyo Metro, carries approximately 6.52 million passengers per day, as of 2023.
