History
Wakōshi Station opened on 1 February 1934 as Niikura Station on the Tōjō Railway, with the name initially written in hiragana and respelled in kanji from 12 July of the same year. The army built a cadet school and arms factories nearby from 1937, and after the war US occupation forces took over the sites as Camp Drake, leaving the area a hybrid of military and industrial uses. The station was renamed Yamato-machi on 1 October 1951 and again to Wakōshi on 20 December 1970 to reflect the new city name. Tokyo Metro Yūrakuchō Line through-service began on 25 August 1987, and Fukutoshin Line through-service followed on 14 June 2008.

Notes
It is the only Tokyo Metro station that lies outside Tokyo Metropolis: it sits in Saitama Prefecture and is at once the westernmost and northernmost station in the entire Tokyo Metro network.
