History
Gaiemmae Station opened on 18 November 1938 as Aoyama-yonchōme on the privately built Tokyo Rapid Railway, the western half of what is now the Ginza Line. It was renamed Gaiemmae on 16 September 1939, taking the alias of the adjacent Meiji Shrine Outer Gardens. Wartime consolidation transferred it to the Teito Rapid Transit Authority on 1 September 1941, and the platforms were extended for six-car operation by July 1957. A major modernisation between 1995 and 2001 widened the platform and concourse and added a second exit set near the Ginkgo Avenue. Tokyo Metro inherited the station on 1 April 2004, and departure melodies were introduced on 22 August 2018.

Notes
After the 2020 reopening of Toranomon Hills broke up Toranomon's standalone status, Gaiemmae became the busiest single-line station on the Ginza Line.
