The Tōzai Line (東西線 Tōzai-sen?) is a 30.8 km subway line of Tokyo Metro in Tokyo, Japan. The route runs east-west in the centre of Tokyo. The western terminus is Nakano Station in Nakano Ward with inter-operating westward to the East Japan Railway Company's Chūō Main Line (Chūō-Sōbu Line Local trains). The eastern end is Nishi-Funabashi Station in the city of Funabashi, Chiba Prefecture, also inter-operating to JR East Chūō-Sōbu Line and the Tōyō Rapid Railway. On maps and signboards, the line is shown in sky blue; stations on the Tōzai Line carry the letter T followed by a two-digit number.

The official name, which is scarcely used, is the Line 5 Tōzai Line (5号線東西線 5gōsen Tōzai-sen?).

The Tōzai Line is the second most-ridden subway line in Japan (after the Midōsuji Line in Osaka), and according to a 2005 study[1], is the country's most crowded during rush hours. Women-only cars were introduced on the line during morning rush hours starting on November 20, 2006.

[edit] Operation

This is currently the only Tokyo Metro line on which Rapid trains run (Three types of Rapid trains skip some stations east of Tōyōchō), but when service commences on the Fukutoshin Line in June 2008, that line will also have express services on it.

The Tōzai Line features inter-running with JR East at Nakano over the Chūō Main Line west to Mitaka; at Nishi-Funabashi over the Tōyō Rapid Railway to Tōyō Katsutadai all day; and over the Sōbu Main Line to Tsudanuma in the morning and evening peaks.

[edit] Development

The Tōzai Line was planned by a review committee of the then Ministry of Transportation in 1962 and numbered Line 5. Its name literally means "East-West Line," and it was primarily planned to relieve traffic on the busy Sōbu Main Line as well as provide a straight crosstown connection through north-central Tokyo. Although this corridor is now served by the Tokyo Metropolitan Bureau of Transportation (Toei) Shinjuku Line and JR Keiyō Line as well, the Tōzai Line continues to operate beyond capacity due to its accessibility to other lines, as well as to growing condominium developments in eastern Tokyo.

The Takadanobaba to Kudanshita section opened in 1964, and the remainder opened in stages until its completion in 1969. Through service with the then Japan National Railways began in 1969 connecting the Chūō and Sōbu lines.

The Tōyō Rapid Railway Line, effectively an eastward extension of the line, opened in 1996.

[edit] Stations

The Tōzai Line is currently the only subway line in Tokyo that has at least one direct connection to every other subway line. The Fukutoshin Line, presently under construction, will cross the Tōzai Line, but will not have a direct connection to it.
