History
Sakuradamon Station is a Tokyo Metro Yūrakuchō Line stop in Kasumigaseki 2-chōme, Chiyoda ward, numbered Y-17 and named after the now-vanished Edo Castle gate of the same name. It opened on 30 October 1974 as part of the Yūrakuchō Line's first segment from the Teito Rapid Transit Authority (TRTA), with the magnetic-stripe tickets that supported new automatic gates at Ikebukuro and Ginza-itchōme already on sale here from day one. The station was inherited by Tokyo Metro at the TRTA privatisation on 1 April 2004, gained PASMO support on 18 March 2007, and switched on platform-edge doors on 11 February 2012. A connecting track between Sakuradamon and Nagatachō reaches the Chiyoda Line at Kasumigaseki, enabling rolling-stock transfers to the Ayase depot.

Notes
The basement-one level once housed the Sakuradamon Control Office, which ran train operations across the Yūrakuchō and Hanzōmon lines until consolidated dispatching moved to the Koishikawa depot in 1994.
