History
Kawaguchi-Motogō Station opened on 28 March 2001 with the inauguration of the Saitama Rapid Railway Line, a third-sector subway extending the Tokyo Metro Namboku Line into Saitama. The underground station serves Motogō 1-chōme in Kawaguchi, Saitama, with a single island platform behind waist-height platform-edge doors. Station-plaza-side elevator access was added on 10 November 2002. PASMO IC fares became valid on 18 March 2007. From 22 September 2016 the station has carried the secondary name 'OKS CAMPUS Ōizumi Kōjō Nearest Station', and on 7 February 2017 a Daily Yamazaki convenience store opened inside the gates. Most services through-run southbound onto the Namboku Line to Meguro and the Tōkyū Meguro Line to Hiyoshi.
