• JR Sanyo Main Line: Wake ⇄ Mantomi

Kumayama Station first appeared as a signal station on 10 July 1917 between Wake and Mantomi on the Railway Bureau's San'yō Main Line. It was upgraded to a full station on 11 August 1930. Freight ended in October 1960 and parcel handling in February 1984. With the privatization of JNR on 1 April 1987 it passed to JR West. ICOCA service began in September 2007, the staffed ticket window closed in May 2019 (the station became unstaffed from 1 June 2019), and station number JR-S08 was introduced in September 2020. The relocated footbridge here was certified as modern industrial heritage in 2009.

The station's footbridge originally stood at Seto Station from 1912 and was relocated to Kumayama in 1960, earning a modern industrial heritage citation from METI in 2009.
