• Nishikigawa Seiryu Line: Shuuchi-Kasagami ⇄ Kawanishi (Yamaguchi)

Seiryū-Shin-Iwakuni Station opened on 1 November 1960 as Mishō Station (御庄駅) on the Japanese National Railways Gannichi Line (岩日線), in what is today the city of Iwakuni, Yamaguchi Prefecture. On 10 March 1975 the Sanyō Shinkansen Shin-Iwakuni Station opened immediately adjacent, but the two stations were kept separate by JNR. With the 1 April 1987 JNR privatisation the station passed to JR West and on 25 July 1987 to the third-sector Nishikigawa Railway. On 16 March 2013 the station was renamed Seiryū-Shin-Iwakuni to publicise the walkable transfer to the neighbouring shinkansen station, roughly 300 metres away.

The 1975 opening of Shin-Iwakuni Station on the Sanyō Shinkansen next door did not consolidate it with the adjacent Mishō halt, which JNR continued to treat as a separate station; the link was written into the station's own name only with the 2013 renaming, and even now the two are operated by different companies, joined by a walkway of about 300 metres along the shinkansen viaduct.
