History
Yoyogi-Kōen Station opened on 20 October 1972 as the western terminus of the Teito Rapid Transit Authority's Chiyoda Line with the inaugural Kasumigaseki-to-here section, in Tomigaya, Shibuya, Tokyo. The station was set up as a transfer point to Odakyū's adjacent Yoyogi-Hachiman Station from the start. When the Chiyoda Line was extended from here to Yoyogi-Uehara on 31 March 1978, Yoyogi-Kōen became an intermediate station and the Odakyū interchange arrangement was dropped. The Eidan subway operator was privatised into Tokyo Metro on 1 April 2004, PASMO IC cards were accepted from 18 March 2007, and platform-edge doors and Switch-composed departure melodies both entered service on 6 October 2018.

Notes
Beneath Yoyogi Park, a Chiyoda Line underground depot capable of holding eight ten-car trains stretches from the station's Omotesandō end; a parallel pit-style siding hugs the platform itself.
