History
Kawanishi opened on 16 April 1960 as an infill stop on the JNR Gantoku Line between Nishi-Iwakuni and Hashirano, accepting only diesel-railcar passengers and unstaffed from the start. It became a nominal branch terminus on 1 November the same year when the JNR Ganzai Line opened to Kawayama. Around autumn 1977 the platform was extended in both directions following a local petition, allowing the previously-passing-through 10-car loco-hauled passenger trains to stop here. The station passed to JR West at privatisation on 1 April 1987, and on 25 July 1987 the Ganzai Line was transferred to Nishikigawa Railway, making the stop a joint JR West/Nishikigawa station.

Notes
Kawanishi is the operational starting point of the Nishikigawa Seiryū Line — a 0-km post sits on the platform — but the physical junction with the JR Gantoku Line is 1.9 km further on at Morigahara Signal Box. The two operators share that 1.9 km section as joint Class-1 rail businesses, and every Nishikigawa Seiryū Line train runs through onto JR tracks to Iwakuni: JR fares apply on the Iwakuni–Kawanishi section even on Nishikigawa Railway rolling stock.
