On March 20, 1921, the Ōminato Light Railway (大湊軽便線 Ōminato-keibensen) began operations between Noheji Station and Mutsu-Yokohama Station. The line was extended to its present terminus of Ōminato Station by September 25, 1921. In 1922, the line was nationalized, and renamed the Ōminato Line of the Japanese Government Railway (JGR, later JNR).
Express Natsudomari operations began from Aomori Station on a seasonal basis began in 1968. The express was later downgraded to rapid service and renamed the Usori, and later the Shimokita. All freight operations were suspended from February 1, 1984. With the dissolution and privatization of the JNR on April 1, 1984, the line came under the control of the East Japan Railway Company. On December 4, 1999 a new centralized traffic control (CTC) system became operational. In 2002, seasonal excursion trains, Kirakira Michinoku operations were started, and a limited number of Shimokita trains were extended to terminate at Hachinohe Station instead of Noheji. The Shimokita service operates a daily round trip to Aomori and 3 round trips to Hachinohe in conjunction with the Aoimori Railway.
The Tōhoku Main Line, including Noheji was transferred from JR East to Aoimori Railway on December 4, 2010. This resulted in the isolation of the Ōminato Line, a branch of the Tōhoku Main Line, from the rest of the JR East network with the exception of the Shimokita service from Aomori where it connects with the Ōu Main Line and Tsugaru Line.
