• JR Sanyo Main Line: Kumayama ⇄ Seto

Mantomi Station opened on 26 December 1897 between Wake and Seto on the Sanyō Railway, handling both passengers and freight from day one. Nationalisation on 1 December 1906 made it an official railway station, and the 1909 naming reform attached it to the Sanyō Main Line. Freight ended on 15 October 1960 but resumed on 5 January 1972 when the Kirin Brewery's Okayama factory and its connecting siding entered service; that operation closed on 1 November 1986. JR West took over on 1 April 1987. ICOCA acceptance began on 1 September 2007. The Midori-no-Madoguchi staffed counter closed on 31 May 2019, and the station has been unstaffed since.

From January 1972 to November 1986 Mantomi handled freight from a private siding into the Kirin Brewery's Okayama factory next door, including malt-import shipments shuttled from Kobe Port.
