The line was originally built to shorten the Sanyo Main Line along the old San'yōdō. The 3.7 km Iwakuni to Marifu (now Nishi-Iwakuni) section opened in 1929, and the 3.9 km Kushigahama to Suo-Hanaoka section opened in 1932. The remaining 36 km section, including the 3,149 m Kinmeiji tunnel (and six others) opened in 1934, at which time the line became part of the Sanyo Main Line, at that time being the only remaining single line section.[ citation needed ]

In 1944 the original Sanyo alignment via Yanai was double-tracked and reinstated as the Sanyo Main Line, at which time this line became formally known as the Gantoku Line.[ citation needed ]

Freight services ceased in 1974, and CTC signalling was commissioned on the entire line in 1982.[ citation needed ]
