• Ibusuki Makurazaki Line: Oyama (Kagoshima) ⇄ Satsuma-Kawashiri

Nishi-Ōyama Station opened on 22 March 1960 as a stop on the JNR Ibusuki Line, in the Yamakawa-Ōyama district of Ibusuki. It began life as an unstaffed station handling passengers from railcars only, and the line serving it was renamed the Ibusuki Makurazaki Line on 31 October 1963. At privatisation on 1 April 1987 the station transferred to JR Kyushu. The stop consists of a single side platform with no building. Sited at 31°11′N, it overtook Yamakawa as Japan's southernmost station on opening, a distinction it held until Yui Rail's Akamine Station opened in Naha in 2003. The marker outside was changed first to "southernmost in the mainland" and, in 2004, to its present "southernmost JR Group station" inscription. Mount Kaimon dominates the view from the platform, and a souvenir-shop annex at the nearby Nakazono Kyūtarō Shōten pickle factory issues "arrival certificates" to visitors.

Since Yui Rail's Akamine Station opened in 2003, Nishi-Ōyama at 31°11′N has been the southernmost station of the JR Group — its marker now reads "southernmost JR Group station." It also remains the southernmost station on Japan's ordinary (conventional) railway network.
