青森站
With the privatization of Japanese National Railways (JNR) on 1 April 1987, the station came under the control of JR East. On 4 December 2010, the Tōhoku Shinkansen was successfully extended north to Shin-Aomori Station from Hachinohe. As a result of the opening of the bullet train between the two stations, that section of the Tōhoku Main Line including the line's platforms at Aomori Station was transferred to the Aoimori Railway Company from JR East on the same day.
