History
Gyōtoku Station opened on 29 March 1969 as a stop on the Eidan Subway Tōzai Line in Ichikawa, Chiba, and bears the station number T 20. Refurbishment works completed on 27 August 1991. With the new Myōden Station opening on 22 January 2000, all Nakano-bound services that had previously started or ended at Gyōtoku were rerouted to start and end at Myōden instead. On 1 April 2004 the Eidan operator was privatised and the station passed to Tokyo Metro. PASMO IC cards were accepted from 18 March 2007. As part of the "Tōzai Line Solar Power Station" programme a 108 kW photovoltaic array was installed on 27 March 2014. Departure-melody chimes began on 11 June 2015, the under-viaduct retail complex M'av Gyōtoku opened on 30 June 2023, and platform-edge doors entered service on 26 July 2025.

Notes
When the Tōzai Line was built Gyōtoku was originally going to have a passing track, so the outer walls of the platform are gently curved away from the centre and a thin corridor still survives between the staircase and the back wall.
