Nishikigawa Seiryū Line

The Nishikigawa Seiryū Line (錦川清流線, Nishikigawa Seiryū-sen, "Nishiki River Clear Stream Line") is a Japanese railway line connecting Kawanishi and Nishikichō stations, all within Iwakuni, Yamaguchi.

As the name suggests, the line parallels the Nishiki River.

The company also operates bus lines and a travel agency.

The Gannichi Line (岩日線, Gannichi-sen) opened to Kawayama on 1 November 1960, operated by Japanese National Railways (JNR), and was extended to Nishikichō in 1963.

The Nishikigawa Railway was established on 1 April 1987, renaming and taking over operations of the line from 25 July of the same year.
