• Tsuyama Line: Tsuyama ⇄ Sarayama

The station opened on 21 December 1898 under the name Tsuyama Station on the Chūgoku Railway, in what was then Sarayama Village across the Yoshii River from Tsuyama Town. When a more convenient new Tsuyama Station opened in 1923 in Fukuoka Village, the original station was renamed Tsuyamaguchi on 1 August 1923. Until the Chūgoku Railway was nationalised in 1944, the station served as the boundary point between the private company and the Japanese Government Railway's Sakubi Line, which later became part of the Kishin and then the Tsuyama Line. Freight and parcel handling ended in November 1971 and the station became unstaffed. JR West took over on 1 April 1987 with the privatisation of JNR, and a new station building was completed in March 2020.

Although named the gateway to Tsuyama, the original Tsuyama Station here lost its role when a new station with the same name opened in 1923 in a more convenient location across the river; the renaming preceded the new station's debut by twenty days.
