History
Nishi-Shinjuku-gochōme Station opened on 19 December 1997 as a stop on the Toei 12-go Line, the section that became the Toei Ōedo Line when the route was renamed on 20 April 2000. The station was added when the line's planned alignment was reworked to serve the Tokyo Metropolitan Government's new Nishi-Shinjuku headquarters, placing a stop between Nakano-sakaue and the relocated metropolitan offices. PASMO support began on 18 March 2007, and on 27 April 2013 platform-door installation here completed the rollout across the entire Ōedo Line. The station carries the secondary name Shimizubashi, taken from a former bridge over the now-culverted Izumi River nearby.
