• Gantoku Line: Iwakuni ⇄ Kawanishi (Yamaguchi)

Nishi-Iwakuni Station opened on 5 April 1929 as Iwakuni Station, the terminus of the partial opening of the Gantoku Line, in what is today the city of Iwakuni, Yamaguchi Prefecture. The original San'yō Main Line Iwakuni Station was simultaneously renamed Marifu. On 1 December 1934 the Gantoku East Line was incorporated into the San'yō Main Line as a new alignment. On 1 April 1942 the station was renamed Nishi-Iwakuni and Marifu reverted to Iwakuni. The wartime rerouting of the San'yō Main Line via Yanai on 11 October 1944 returned the station to the Gantoku Line. The station passed to JR West at the 1 April 1987 JNR privatisation. The 1929 station building was registered as a national tangible cultural property on 3 August 2006.

The 1929 station building was registered as a national tangible cultural property in 2006 and is now also used by a local NPO as a community exchange centre.
