Tokyo Metro

The Tokyo Metro (東京メトロ Tōkyō Metoro) is a major rapid transit system in Tokyo, Japan. While it is not the only rapid transit system operating in Tokyo, it has the higher ridership among the two subway operators: in 2014, the Tokyo Metro had an average daily ridership of 6.84 million passengers, while the other system, the Toei Subway, had 2.85 million average daily rides. The company replaced the Teito Rapid Transit Authority (帝都高速度交通営団 Teito Kōsokudo Kōtsū Eidan), commonly known as Eidan or TRTA, on April 1, 2004.

Tokyo Metro has indicated in the public share that it will cease line construction once Fukutoshin Line has been completed. The line was completed in 2013 with the opening of the line connection at Shibuya Station, but there are several lines such as Hanzomon Line that still have extensions in the official plans and in the past, these plans have tend to happen but often in several decades.

There are also some other rail project proposals in Tokyo which would involve large-scale tunneling projects, but these are unlikely to involve Tokyo Metro. The only proposal that has any suggestion of possible Tokyo Metro involvement is the prominent project proposed as a new Narita and Haneda Airport connection through a tunnel through central Tokyo to a new station adjacent to the existing Tokyo Station. This line is often described as a bypass of the current Toei Asakusa Line. It would link the Keisei Oshiage Line (with service to Narita Airport) to the Keikyu Main Line (with service to Haneda Airport) through Tokyo Station. The 400 billion yen project would be largely divided between the Tokyo metropolitan government and the Japanese central government (which is similar to the structure of Tokyo Metro) with the rail operator or operators paying the balance. The suggestion of Tokyo Metro involvement comes mostly from its description as a bypass to the Asakusa Line which might imply it to be a subway line, but the principle proposal only includes one stop in Tokyo (at Tokyo Station). The principle justification of the proposal is to reduce connection time from Narita Airport to Tokyo Station by 13 minutes, and the design of the proposal makes this much more a high-speed rail project than a subway project (though, it would likely not be up to all of Japan's Shinkansen high-speed rail standards). Currently the only high-speed connection to the Narita Airport is the Keisei Skyliner which runs to Ueno, but there is ordinary train service between these airports using the Asakusa Line. The proposal would essentially allow the Skyliner to run to the more important Tokyo Station as well as establish a high-speed connection to the Haneda Airport.

Nine lines include:
 * Line 2: Hibiya Line
 * Line 3: Ginza Line
 * Line 4: Marunouchi Line
 * Line 5: Tozai Line
 * Line 7: Namboku Line
 * Line 8: Yurakucho Line
 * Line 9: Chiyoda Line
 * Line 11: Hanzomon Line
 * Line 13: Fukutoshin Line

Several trains were donated to Buenos Aires, which is the Eidan 500 series, Nagoya 300/700/1200 series as well as Nagoya 5000 series. Some of the 203 series trains were shipped to Kereta Commuter Indonesia (KCI) in 2011. One of the train in the same batch was involved in the sarin gas attack in 1995.

Fukutoshin is Japanese for "secondary city center", and the Fukutoshin Line connects three of Tokyo's secondary city centers: Ikebukuro, Shinjuku and Shibuya. Prior to its opening, only JR East had rail service between the three (on the Yamanote Line, the Saikyō Line and the Shōnan-Shinjuku Line). The new line was conceived to relieve congestion along this busy corridor, and to provide convenient through service between the northwest, the southwest and the central part of Tokyo served by the Yamanote Line. The line was initially planned to run from Shiki, Saitama to Shinjuku, with the possibility of going to Shibuya and Haneda Airport. A 3.2km of the Kotake-Mukaihara to Ikebukuro, running parallel to Yurakucho Line (which is called Yurakucho New Line), opened in 1994. The newest segment was completed on 14 June 2008, via Zoshigaya, Nishi-waseda, Higashi-shinjuku, Shinjuku-sanchome, Kita-sando and Meiji-jingumae (Harajuku).
