History
Higashi-ginza Station opened on 28 February 1963 as a joint Toei Line 1 and Teito-Rapid-Transit Authority Hibiya Line station, with the two operators sharing a single ticket window from day one. Toei's Line 1 was renamed the Asakusa Line on 1 October 1978. Privatisation moved the Hibiya Line platform to Tokyo Metro on 1 April 2004, and PASMO acceptance began on 18 March 2007. Departure melodies entered service in March 2019 on the Asakusa Line and February 2020 on the Hibiya Line. The Toei side numbers its platforms consecutively with the Tokyo Metro side — an unusual courtesy between two separate operators in Japan.

Notes
Higashi-ginza is one of the very few interchanges in Japan where two different operators agreed to number their platforms consecutively rather than restarting each company's count.
