The Chiyoda Line (千代田線 Chiyoda-sen?) is a rapid transit line of the Tokyo Metro in Tokyo, Japan, with proper name Line 9 Chiyoda Line (9号線千代田線 9-gō sen Chiyoda-sen?) which is scarecely used.

Trains interoperate on both ends: more than half trains to the north-east with the East Japan Railway Company (JR East) Jōban Line beyond Ayase down to Toride; some to the south-west with the Odakyū Electric Railway Odawara Line beyond Yoyogi-Uehara down to Hon-Atsugi, and more trains than to Hon-Atsugi, to Karakida on Tama Line.

The 21.9 km main line serves the wards of Tokyo: Adachi, Arakawa, Bunkyō, Chiyoda, Minato and Shibuya; a short stretch of tunnel in Taitō with no station. A 2.1km branch line goes from Ayase to Kita-Ayase both in Adachi.

The colour of the line shown on maps and signboards is dark green, and EMUs of Tokyo Metro proper are lined with the colour (see photograph). Station numbers carry the preceding letter C. Automatic Train Operation is used on the line between Ayase and Kita Ayase.

[edit] Development

The Chiyoda Line was originally proposed in 1962 as a line from Setagaya to Matsudo, Chiba Prefecture: the initial name was Line 8. In 1964, the plan was changed slightly so that through service would be offered on the Jōban Line north of Tokyo, and the number was changed to Line 9.

Line 9 was designed to pass through build-up area in Chiyoda, and also intended to relieve the busy Ginza Line and Hibiya Line, which follow a roughly similar route through central Tokyo.

The first stretch was opened on December 20, 1969 between Kita-Senju and Ōtemachi. The line was almost completed by October 10, 1972 when it reached Yoyogi-Kōen, although the 1 km section to Yoyogi-Uehara was not completed until March 31, 1978. The branch line to Kita-Ayase was opened on December 20, 1979.

In May 15, 2006, women-only cars were introduced on early-morning trains from Toride on the Jōban Line to Yoyogi-Uehara.

Odakyū currently plans to begin Limited Express trains through service to the Chiyoda Line in 2008, which would mark the first time that a Japanese subway system has accommodated reserved-seating trains.
