History
Gokokuji Station opened on 30 October 1974 when the Teito Rapid Transit Authority (TRTA) inaugurated the initial Ikebukuro–Ginza-itchōme stretch of the Yūrakuchō Line. Magnetic-stripe tickets were sold from the outset because the line's terminus stations used automatic gates from opening day. Operation passed from TRTA to Tokyo Metro on 1 April 2004 when the authority was privatised. PASMO acceptance began on 18 March 2007, and half-height platform-edge doors were introduced on 26 March 2011 as part of a Yūrakuchō Line-wide retrofit. The station is the westernmost stop in Bunkyō ward and bears the line code Y 11; departure melodies "Bōken Densha" and "Kazaguruma" have been used on platforms 1 and 2 since the platform-door rollout.

Notes
Kodansha's headquarters next door has a basement entrance built directly into the station, added when the publisher rebuilt its main offices.
