Two subway systems (Japanese: 地下鉄, Hepburn: chikatetsu) operate in Tokyo: Tokyo Metro and the Toei Subway. Most of the network is located in the 23 special wards, with portions extending into Chiba and Saitama Prefectures. The subways are one part of Greater Tokyo's passenger rail network, with through service further connecting the subway to suburban railways in Western Tokyo and Kanagawa Prefecture.
There are two primary subway operators in Tokyo:
As of 2023 [update] , the combined subway network of the Tokyo and Toei metros comprises 286 stations and 13 lines covering a total system length of 304.0 kilometers (188.9 mi). The Tokyo Metro and Toei networks together carry a combined average of over eight million passengers daily. Despite being ranked second overall in worldwide subway usage (after the Shanghai Metro) as of 2019, subways make up a relatively small fraction of heavy rail rapid transit in Tokyo alone—only 286 out of 938 railway stations, as of 2020. The Tokyo subway at 8.7 million daily passengers only represents 22% of Tokyo's 40 million daily rail passengers (see Transport in Greater Tokyo). Other urban commuter rail systems include Keikyu Corporation (formerly the Keihin Electric Express Railway), Keio Corporation, Keisei Electric Railway, Odakyu Electric Railway, Seibu Railway, Tobu Railway and Tokyu Corporation.

In addition, but not formally designated as subways:
The Yokohama Subway and the Minatomirai Line also operate in the Greater Tokyo Area, but they are not directly connected to the Tokyo subway network. However, direct through services from the Tokyo Metro Fukutoshin Line regularly run into Yokohama's Minatomirai Line via the Tōkyū Tōyoko Line.
Both the Tokyo Metro and Toei Subway systems are closely integrated with a unified system of line colors, line codes, and station numbers. However, the separate administration of metro systems has some ramifications:
As is common with Japanese subway systems, many above-ground and underground lines in the Greater Tokyo Area operate through services with the Tokyo Metro and Toei lines. Through services operate on all lines except Tokyo Metro Ginza and Marunouchi Lines and Toei Oedo Line. In a broader sense they are considered a part of the Tokyo subway network, allowing it to reach farther out into the suburbs.
