No publicly available departure data for this station.

Minami-Ōtsuka Station opened on 14 November 1897 as a Kawagoe Railway stop, added two years after the line's initial Kume-gawa (now Higashi-Murayama) to Kawagoe section began service. From 15 February 1925 the station was also the start of the Ahina freight branch, used to haul Iruma River gravel; that branch was suspended in 1963 and formally abolished on 31 May 2017. A new elevated-walkway station building opened on 22 December 1980, with the depot relocated about 100 m toward Tokorozawa. Operation has always been by Seibu Railway. In fiscal 2012 the station was assigned the number SS28, and on 27 March 2025 it became a remotely operated stop with on-site ticket sales discontinued.

The disused Ahina freight branch crossed where the station's north entrance now passes, and surviving track sections are still visible alongside platform 1.
