History
Aoyama-itchōme Station opened on 18 November 1938 as a stop on the privately built Tokyo Rapid Railway, the western half of what is now the Ginza Line. Wartime consolidation transferred it to the Teito Rapid Transit Authority on 1 September 1941. Platforms were extended for six-car operation by 1957. The Hanzōmon Line platform opened on 1 August 1978, initially in single-track service that ran in unusual reverse-direction-only patterns until full double-track operation resumed in December 1982. The Toei Ōedo Line platform opened on 12 December 2000. Privatisation moved the Ginza and Hanzōmon platforms to Tokyo Metro on 1 April 2004.

Notes
Although the station is named for Aoyama-itchōme, the address "Aoyama" itself has never officially existed as a town name; planners borrowed the long-standing intersection label.
