Because of trouble financing rainstorm damage repairs, the line had no rail service between Aizu-Kawaguchi and Tadami station from July 2011 until October 2022.

Due to the many curves on the line trains take over four hours to traverse its 135.2 km (84.0 mi) length.

In 1963, after the dam was completed, the construction railway was upgraded and opened to Tadami as part of the eastern section.

[citation needed] Damage from heavy rain storms in July 2011 forced the section of the line between Aizu-Kawaguchi and Ōshirakawa to be closed.

[9] After 11 years with a replacement bus service, the closed section resumed operations on 1 October 2022.
