Soja Station opened on 17 February 1925 as Nishi-Soja, when the Hakubi South Line opened between Kurashiki and Shiso (now Gokei). The Chugoku Railway's Kibi Line was extended from the original Soja (now Higashi-Soja) to this station on 7 August 1925. The Hakubi South Line was incorporated into the Hakubi Line in 1928, and the Kibi Line was nationalised on 1 June 1944. The station was renamed Soja on 1 November 1959 and passed to JR West at the 1987 privatisation. On 11 January 1999 the third-sector Ibara Railway connected to the station, sharing the running line between Kiyone and Soja with the JR Hakubi Line.
