  The section from Morioka to Shizukuishi opened on 25 June 1921, as the Hashiba Light Railway (橋場軽便), and was extended to Hashiba on 2 September 1922. Services to Hashiba Station ended in the 1940s.
  
  In 1964, the Shizukuishi to Akabuchi section opened, and upon completion of the 3,915 m (2.433 mi) Sengan Tunnel, the Akabuchi to Tazawako section opened on 20 October 1966, completing the line.
  
  Freight services ceased in 1982, the year the entire line was electrified.
  
  In 1997, the line was converted to 1,435 mm (4 ft 8+1⁄2 in) gauge, and became part of the Akita Shinkansen, with standard-gauge electric multiple unit (EMU) trains providing local services on the line.
  
  In January 2022 it was announced that Maegata Station would be added between Morioka Station and Ōkama Station. Maegata station opened for service on 18 March 2023.
