The Iiyama Railway Co. opened the first section from Toyono to its namesake town in 1921, and extended the line in sections to Tokamachi in 1929, where it connected to the Japanese Government Railways line from Echigo-Kawaguchi which had opened in 1927.
The Iiyama Railway Co. was nationalised in 1944, and freight services ceased in 1987.
The line sees much snow in the winter. The line uses avalanche fences along steep slopes, snow sheds and has a melting system at level crossings to deal with the snow. A record 7.85m of snow fell at Mori-Miyanohara Station in February 1945, an event that is remembered with a pole just outside the station marking the vast amount of snow.
