Iwakuni Station opened on 25 September 1897 on the privately built San'yō Railway as part of the line's extension from Hiroshima to Tokuyama, in what is today the city of Iwakuni, Yamaguchi Prefecture. The San'yō Railway was nationalised in 1906 and the line renamed the San'yō Main Line in 1909. The station was renamed Marifu on 3 February 1929 but reverted to Iwakuni on 1 April 1942. The American air raid of 14 August 1945 burned down the station building, and a third-generation structure opened in 1949. Following the 1 April 1987 JNR privatisation the station passed to JR West and JR Freight. A fourth station building elevated above the tracks was inaugurated on 26 November 2017.

Iwakuni Station was renamed Marifu in 1929 after the town it stood in, and the name Iwakuni passed that April to the newly opened terminus of the Gantoku Line — the station known today as Nishi-Iwakuni. This station took the name Iwakuni back on 1 April 1942.
