• Aoimori Railway Line: Suwanotaira ⇄ Metoki

Sannohe Station opened on 1 September 1891 as 三ノ戸駅 (Sannohe Station, with a different kanji rendering) of the privately owned Nippon Railway. When Nippon Railway was nationalised on 1 November 1906, it became a station on the Tōhoku Main Line, and its name was rewritten to the present form (三戸駅) on 1 November 1907. Freight handling was discontinued on 1 February 1984 and baggage handling on 1 November 1986. With the privatisation of Japan National Railways on 1 April 1987 the station passed to East Japan Railway Company (JR East). On 1 December 2002 it transferred again to the third-sector Aoimori Railway Company on the Tōhoku Shinkansen's extension to Hachinohe, and on 12 March 2022 it became unstaffed.

The town the station serves, Sannohe, lies on the opposite bank of the Mabechi River — the station building itself is in Nanbu, and passengers must cross the river to reach Sannohe town.
