All trains are local (all-stations) services, with approximately eight to nine trains in each direction per day. Only three round-trips operate over the entire line, and some seasonal trains operate through onto the line from the Ban'etsu West and Jōetsu lines.[1]

Due to the many curves on the line trains take over four hours to traverse its 135.2 km length.

The Aizu-Wakamatsu - Aizu-Yanaizu section opened between 1926 and 1928. The line was extended to Aizu-Miyashita in 1941.

At the western end, the Koide - Oshirakawa section opened in 1942.

The Aizu-Miyashita - Aizu-Kawaguchi section opened in 1956, with the extension to Tadami opening in 1963.

The two sections were connected with the opening of Tadami - Oshirakawa (as a passenger only section) in 1971.

Freight services ceased between 1980 and 1982.

Service disruptions

Heavy rain storms in July 2011 forced the section of the line between Aizu-Kawaguchi and Ōshirakawa to be closed. The section between Tadami and Ōshirakawa was reopened from 1 October 2012, but the schedule for reopening the remaining section between Aizu-Kawaguchi and Tadami is indefinite.[2] A replacement bus operates where the line is interrupted.
