The 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".
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. 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 Aum sarin gas attack on 20 March 1995.
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 Hakone-Yumoto (on the Hakone Tozan Line) and Karakida (on the Odakyu Tama Line). Trains also run from/to Shin-Kiba using tracks connecting to the Yurakucho Line.
On March 16, 2019, 10 car services to Kita-Ayase station commenced.
