The station, as well as most of the structures in the surrounding area, was destroyed by the 2011 Tōhoku earthquake and tsunami and has now been replaced by a provisional bus rapid transit line.

Wakinosawa Station had a single side platform, serving traffic in both directions.

On 23 May 1960, a tsunami caused by the Great Chilean earthquake submerged both this station and neighbouring Otomo Station, making the line temporarily impassable until the water is removed.

The station was absorbed into the JR East network upon the privatization of the Japan National Railways (JNR) on April 1, 1987.
