History
Suwanotaira Station opened on 15 January 1933 as a station on the Tōhoku Main Line under the Railway Ministry (later Japan National Railways), serving the town of Nanbu in Aomori Prefecture. Freight operations ended in April 1962, baggage handling was withdrawn on 1 May 1980, and the station became a contracted-out station without staff. Following the 1 April 1987 privatisation of JNR the station was transferred to East Japan Railway Company (JR East), and on 1 December 2002 it was transferred again to the third-sector Aoimori Railway Company on the extension of the Tōhoku Shinkansen to Hachinohe. The ticket vending machine was withdrawn on 28 February 2017.

Notes
The platforms sit on a curve with significant superelevation, so trains stop noticeably tilted.
