History
Shinjuku-gyoemmae Station opened on 15 March 1959 as a stop on the Teito Rapid Transit Authority's Marunouchi Line, named for the imperial garden it serves. The two side platforms are arranged in a staggered configuration roughly 20 metres offset from each other, an artefact of the cut-and-cover construction along Shinjuku-dōri. The Marunouchi Line passed to Tokyo Metro on 1 April 2004 when Teito Rapid Transit Authority was privatised, and PASMO support began on 18 March 2007. Platform-edge doors were installed in December 2006 to support one-person operation introduced on 28 March 2009, and a third entrance with an elevator was opened on 11 July 2009. The garden's cherry-blossom season produces the year's highest passenger surges.

Notes
The Oginbo-bound (A-line) and Ikebukuro-bound (B-line) platforms are staggered roughly 20 metres apart along the tunnel rather than directly opposite each other.
