Shimoyama Station opened on 1 July 2002 as an intermediate stop on the Tosa Kuroshio Railway's new Asa (Gomen–Nahari) Line in Aki, Kōchi Prefecture, 34.7 km from the line's origin at Gomen. The station sits on an embankment, with two opposed side platforms reached by stairs and a foot underpass; there is no station building, just enclosed and open shelters on each platform plus a separate waiting room and bike shed in the forecourt. Operated by the third-sector Tosa Kuroshio Railway, the stop carries station number GN25 and is served by all Asa Line rapid and local trains, except those terminating at Aki.

Shimoyama's cartoon mascot "Shimoyama Chidori-chan" is a girl in a blue yukata with a white plover on her head — a nod to the children's song Hama Chidori, written by local composer Ryūtarō Hirota whose monument stands at nearby Cape Ōyama.
