Tokyo Metro has joined the CoMET group of metros. Their system is the oldest in Asia, dating to 1927 with the opening of the Ginza Line. Privatised in 2004, Tokyo Metro is owned by the national and metropolitan governments. The Tokyo Metro network is 195.1km with 179 stations on 9 lines and is renowned for its punctuality. Annual passenger journeys are estimated at more than 2.2 billion, making Tokyo Metro among the densest metros in the world.
Tokyo Metro’s first two lines, the 1927 Ginza Line and 1954 Marunouchi Line, operate on standard gauge track with third rail power and are independent. The rest of the network operates on narrow gauge (1067mm) like the mainline railway network in Japan, with overhead power and operate through services connecting to various suburban railways. We look forward to working with Tokyo Metro on benchmarking going forward.
