The Aizu Line was constructed between 1927 and 1953 by the Japanese National Railways (JNR) as part of a plan to build a direct line from Aizu-Wakamatsu to Tokyo. The Aizu Line was the northern section, whilst the Yagan Railway Aizu Kinugawa Line was to be the southern section. Despite the Kinugawa line connecting to the Aizu Line in 1986, the Aizu Line was deemed an unprofitable secondary line and transferred to a company established by local governments in 1987.
The Aizukōgen-Ozeguchi - Aizu-Tajima section was electrified at 1500V DC in 1990 to facilitate through-running onto the Kinugawa line.
