HistoryThe Chiyoda Line was originally proposed in 1962 as a line from Setagaya in Tokyo to Matsudo, Chiba; 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, 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 and . The line was almost completed by October 10, 1972 when it reached, although the section to was not completed until March 31, 1978. The branch line to 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 operated between Ayase and Kita-Ayase. The Chiyoda Line was one of the lines targeted in the Aum sarin gas attack on March 20, 1995. On May 15, 2006, women-only cars were introduced on early-morning trains from on the Joban Line to . 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 (on the Hakone Tozan Line) and (on the Odakyu Tama Line). Trains also run from/to using tracks connecting to the Yurakucho Line. On March 16, 2019, 10-car trains commenced operation on the branch line to Kita-Ayase station after platforms were lengthened by 135m, allowing direct services from Kita-Ayase to Yoyogi-Uehara.[22] Notesa.
