• Nankai Koya Line: Koyashita ⇄ Kami-Kosawa

Shimo-Kosawa Station opened on 18 June 1928 when the Kōyasan Electric Railway built the line from Kōyashita to Jinya (now Kii-Jinya) in what is now Kudoyama, Wakayama Prefecture. The 1947 corporate restructuring of the Kōyasan Electric Railway into the present Nankai Electric Railway brought the station into the latter's network. The passing loop was removed in November 2002, leaving the station as the Kōya Line's only single-track halt. After Typhoon Lan damaged the roadbed at neighbouring Kami-Kosawa in October 2017, the passing-loop function was relocated here on 31 March 2018, restoring both an inactive platform and on-site staffing. The station was destaffed again on 10 October 2023.

After the passing loop was removed in 2002, only the Namba-bound platform stayed in use, and from October 2007 the disused Kōyasan-bound platform was given a "flower screen" of plantings as part of the Kōya Flower Railway Project — only for it to be torn out again when the recovery from the 2017 typhoon brought the loop back into service in 2018 and the down platform was rebuilt.
