History
Tamba-Ōyama Station opened on 25 May 1899 as Ōyama Station, a passenger and freight stop on the Hankaku Railway between Sasayamaguchi and Kaibara, after Ajima village mayor Mori Rokubē donated land to secure its construction. Nationalised in 1907, it was assigned to the Hankaku Line in 1909 and to the Fukuchiyama Line in 1912, then renamed Tamba-Ōyama on 1 May 1917 to avoid confusion with similarly named stations. Freight handling ceased in 1962 and the station was reduced to unstaffed operation in 1973. Operations passed to JR West with the 1987 privatisation, and ICOCA support began on 13 March 2021.

Notes
The station owes its existence to Mori Rokubē, the first mayor of Ajima village, who donated his own land to the Hankaku Railway; villagers later erected a memorial stone to him on a hill overlooking the platform in 1915.
