The Aoimori Railway Company was founded on 25 May 2001. Following the beginning of Tōhoku Shinkansen services between Morioka Station and Hachinohe Station on 1 December 2002, the company began operating services along the former Tōhoku Main Line - the corresponding section of which was subsequently renamed as the Aoimori Railway Line - between Metoki Station and Hachinohe Station. When the shinkansen was extended north from Hachinohe to Shin-Aomori Station on 4 December 2010, the company assumed control of the bypassed section of the Tōhoku Main Line between Hachinohe Station and Aomori Station and added it to the Aoimori Railway Line.
