Aniai Line
On December 10, 1934, the Japanese Government Railways (JGR) opened the Aniai Line (阿仁合線) connecting Takanosu with Yonaizawa over a length of 15.1 kilometers. Following World War II, the JGR became the Japanese National Railways (JNR), and the line was further extended to Hitachinai by October 15, 1963.

Kakunodate Line
On November 1, 1971, the JNR Kakunodate Line began operations from Kakunodate to Matsuba, with construction continuing north towards Hitachinai to provide a connection to the Aniai Line. However construction was suspended in 1980 due to JNR funding constraints.

Closure
The Kakunodate Line was closed by JNR on 11 September 1981, and the Aniai Line on 22 June 1984.

Reopening
The third-sector Akita Nairiku Jūkan Railway Company reopened both the Aniai Line (as the Akita Nairiku Kita Line) and the Kakunodate Line (as the Akita Nairiku Minami Line) on November 1, 1986. It also recommenced construction of the suspended link (known as the New Line) which opened on April 1, 1989 creating the current through-route.
