The 21.9&nbsp;km main line serves the [[wards of Tokyo|wards]] of [[Adachi, Tokyo|Adachi]], [[Arakawa, Tokyo|Arakawa]], [[Bunkyō, Tokyo|Bunkyō]], [[Chiyoda, Tokyo|Chiyoda]], [[Minato, Tokyo|Minato]] and [[Shibuya, Tokyo|Shibuya]], and a short stretch of tunnel in [[Taitō, Tokyo|Taitō]] with no station. A 2.1&nbsp;km branch line between Ayase and Kita-Ayase is located in Adachi. Its official name, rarely used, is {{Nihongo|Line 9 Chiyoda Line|9号線千代田線|kyūgō sen Chiyoda-sen}}. On maps, diagrams and signboards, the line is shown using the color green, and its stations are given numbers using the letter "C". Trains have [[through train|through running]] onto other railway lines on both ends. More than half of these are trains to the northeast beyond Ayase onto the [[East Japan Railway Company]] (JR East) [[Joban Line]] to {{STN|Toride}}. The rest run to the southwest beyond Yoyogi-Uehara onto the [[Odakyū Odawara Line]] to {{STN|Hon-Atsugi}} and to {{STN|Karakida}} on the [[Odakyu Tama Line]]. According to the [[Tokyo Metropolitan Bureau of Transportation]], as of June 2009 the Chiyoda Line was the second most crowded subway line in Tokyo, at its peak running at 181% capacity between [[Machiya Station|Machiya]] and [[Nishi-Nippori Station|Nishi-Nippori]] stations.<ref>{{cite journal| journal=Metropolis| url=http://archive.metropolis.co.jp/tokyo/794/page2.asp| title=Commute| date=June 12, 2009| page=7}} Capacity is defined as all passengers having a seat or a strap or door railing to hold on to.</ref> ==Basic data== *Distance: {{convert|24.0|km|mi|2|abbr=on}} ** Main line: {{convert|21.9|km|mi|2|abbr=on}} ** Branch line: {{convert|2.1|km|mi|2|abbr=on}} *Double-tracking: Entire line *[[Railway signalling]]: CS-[[Automatic Train Control|ATC]] == Station list == * All stations are located in Tokyo. * Stopping patterns: ** Local trains stop at every station. ** Odakyū ''[[Romancecar]]'' limited express services stop at stations marked "●" and does not stop at those marked "｜". ** The Odakyū ''Bay Resort'' limited express service does not stop at stations marked "▲".

In 1964, the plan was changed slightly so that through service would be offered on the [[Joban Line]] north of Tokyo, and the number was changed to "Line 9". Line 9 was designed to pass through built-up areas in [[Chiyoda, Tokyo|Chiyoda]], and also intended to relieve the busy [[Tokyo Metro Ginza Line|Ginza Line]] and [[Tokyo Metro Hibiya Line|Hibiya Line]], which follow a roughly similar route through central Tokyo. The first stretch was opened on December 20, 1969 between {{STN|Kita-Senju}} and {{STN|Ōtemachi|Tokyo}}. The line was almost completed by October 10, 1972 when it reached {{STN|Yoyogi-Kōen}}, although the 1&nbsp;km section to {{STN|Yoyogi-Uehara}} was not completed until March 31, 1978. The branch line to {{STN|Kita-Ayase}} was opened on December 20, 1979. This branch primarily serves as a connection to Ayase Depot, but also serves Kita-Ayase station constructed in the area. A three-car shuttle service operates between Ayase and Kita-Ayase. The Chiyoda Line was one of the lines targeted in the [[Tokyo subway sarin attack|Aum sarin gas attack]] on 20 March 1995. On May 15, 2006, [[women-only car]]s were introduced on early-morning trains from {{STN|Toride}} on the [[Joban Line]] to [[Yoyogi-Uehara Station|Yoyogi-Uehara]]. On March 18, 2008, the Chiyoda Line became the first subway line in Japan with operations by reserved-seating trains when Odakyu ''[[Romancecar]]'' [[limited express]] services began running between Kita-Senju and {{STN|Hakone-Yumoto}} (on the [[Hakone Tozan Line]]) and {{STN|Karakida}} (on the [[Odakyu Tama Line]]).
