Railway line in Aomori prefecture, Japan

The Aoimori Railway Line (青い森鉄道線) is a regional rail line in Aomori Prefecture, Japan that is operated by the Aoimori Railway Company. It connects the terminal station of the Iwate Galaxy Railway Line, Metoki Station, in the town of Sannohe to Aomori Station, the terminus of several rail lines in the city of Aomori. The Aoimori and Iwate Galaxy Railway Lines are former sections of the Tōhoku Main Line that connected Tokyo to Aomori that were rendered obsolete for long distance passenger services by the completion of the high speed Tōhoku Shinkansen between and stations. Though local passenger services are run on the line by the Aoimori Railway Company, the East Japan Railway Company continues to operate limited services, such as the sightseeing train Resort Asunaro, along the line, and the Japan Freight Railway Company (which owns a minority stake on the Aoimori Railway Company) transports freight along the line.

The predecessor to the Aoimori Railway Line was completed as the – portion of the Nippon Railway on 1 September 1891. When the Nippon Railway was nationalized on 1 November 1906, it became part of the Japanese National Railways (JNR) system and was designated part of the Tōhoku Main Line on 12 October 1909. With the privatization and dissolution of JNR on 1 April 1987, the line came under the control of the East Japan Railway Company (JR East). On 1 December 2002, with the opening of the Tōhoku Shinkansen, the portion of the Tōhoku Main Line located in Iwate Prefecture became the Iwate Galaxy Railway Line, and the portion in Aomori Prefecture from the Iwate border to Hachinohe Station became the Aoimori Railway Line. With the opening of the Tōhoku Shinkansen extension to on 4 December 2010, the Tōhoku Main Line tracks between Hachinohe and Aomori were transferred from JR East to the Aoimori Railway Company, resulting in the completion of the Aoimori Railway Line. There have been a few new developments along the line since its transfer to the Aoimori Railway Company. On 12 March 2012, Nonai Station was relocated southwest of its original location. Tsutsui Station, near Aomori High School, was opened on 15 March 2014. Two car Aoimori 703 series sets began operations on the line on the same day to handle the increased loads presented by the opening of Tsutsui Station.

The Aoimori Railway Line is operated by the Aoimori Railway Company, a "third sector" publicly and privately owned company. The railway facilities and tracks are owned by the prefectural government of Aomori as a "Category 3 Railway Business" under the Railway Business Act of Japan. The Aoimori Railway Company leases these facilities from the prefectural government and is responsible for operation of passenger trains on the tracks. This scheme is intended to mitigate the company's burden as an owner of fixed assets and is known as "track/service separation" (上下分離方式). The Aoimori Railway Line is designated as the rail line between Aomori and Metoki stations that was formerly the northernmost section of the Tōhoku Main Line. Trains operated by the Aoimori Railway Company primarily operate between Aomori and Hachinohe stations; however, some of the railway's trains continue south beyond Hachinohe to Sannohe Station, with fewer continuing south to Morioka Station. Some of the trains that run along the railway between Hachinohe and Metoki Station are carried by the rolling stock of the Iwate Galaxy Railway Company, the operator of the former Tōhoku Main Line between Metoki and Morioka stations. Japan Freight Railway Company (JR Freight), the nationwide freight train operator, continues to use the line for freight services. As of January 2021, the only JR East limited express operate along the line is the Resort Asunaro sightseeing train that runs between and stations, using the line between Hachinohe and .
