the initial name was "Line 8". 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. [[File:TRTA 6000 and OER 9000 at Yoyogi-Uehara Station 19780331.jpg|thumb|Opening ceremony of through services at [[Yoyogi-Uehara Station]], with an Odakyu 9000 series and TRTA 6000 series present, 31 March 1978]] 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 {{Cvt|1|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 March 20, 1995. On May 15, 2006, [[women-only car]]s were introduced on early-morning trains from {{STN|Toride}} on the [[Joban Line]] to {{STN|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]]). Trains also run from/to {{STN|Shin-Kiba}} using tracks connecting to the [[Tokyo Metro Yūrakuchō Line|Yurakucho Line]]. On March 16, 2019, 10 car services to Kita-Ayase station commenced. ==Notes== {{refbegin|}} a. {{note|notes1}}Crowding levels defined by the [[Ministry of Land, Infrastructure, Transport and Tourism]]:<ref>{{Cite web|url=https://www.mlit.go.jp/tetudo/toshitetu/03_04.html|title = 混雑率の推移}}</ref><ref>{{cite web|url=https://www.japantimes.co.jp/news/2017/07/06/national/tokyo-plans-new-effort-ease-crowding-rush-hour-trains/ |title=Tokyo plans new effort to ease commuter hell on rush-hour trains |first=Daisuke |last=Kikuchi |date=6 July 2017 |work=[[The Japan Times]] |archive-url=https://web.archive.org/web/20170706120354/http://www.japantimes.co.jp/news/2017/07/06/national/tokyo-plans-new-effort-ease-crowding-rush-hour-trains/ |archive-date=6 July 2017 |url-status=live}}</ref> :100% — Commuters have enough personal space and are able to take a seat or stand while holding onto the straps or hand rails. :150% — Commuters have enough personal space to read a newspaper. :180% — Commuters must fold newspapers to read. :200% — Commuters are pressed against each other in each compartment but can still read small magazines. :250% — Commuters are pressed against each other, unable to move. {{refend}} ==References== {{Portal|Tokyo}} {{refbegin}} * {{cite book| last1=Shaw| first1=Dennis| last2=Morioka| first2=Hisashi| title=Tokyo Subways| year=1992| publisher=Hoikusha Publishing}} {{refend}} {{Reflist}} ==External links== {{Commons category}} * [http://www.tokyometro.jp/global/en/index.html Tokyo Metro website] {{Tokyo transit}} {{DEFAULTSORT:Chiyoda Line}} [[Category:Tokyo Metro Chiyoda Line| ]] [[Category:Lines of Tokyo Metro]] [[Category:Railway lines in Tokyo]] [[Category:Railway lines opened in 1969]] [[Category:1067 mm gauge railways in Japan]] [[Category:1500 V DC railway electrification]]'
