• JR Sanyo Main Line: Kamigori ⇄ Yoshinaga

Mitsuishi Station was first opened on 1 December 1890 as a temporary terminus of the San'yō Railway, situated within Hyōgo Prefecture some 3.2 kilometers east of the present site near the eastern portal of the Funasaka Tunnel. On 18 March 1891 the line was extended west to Okayama and the station relocated to its current location in Bizen, Okayama Prefecture. The San'yō Railway was nationalised on 1 December 1906, and the line was designated part of the San'yō Main Line under the rail-naming reform of 12 October 1909. Freight services ceased on 25 December 1983. The station passed to JR West at the 1 April 1987 privatisation, became unmanned from 1 June 2016, and gained an ICOCA-compatible simple ticket gate on 15 September 2018.

The 12.8-kilometer gap between Mitsuishi and the neighboring Kamigōri Station is the longest distance between adjacent stations on any JR West conventional line, a record acquired in 2024 after a previous record-holding section transferred to a third-sector operator.
