Rikuzen-Yokoyama Station had one side platform serving a single-bi-directional track. The station was unattended. This has been changed to a ground-level platform serving bus rapid transit service.
Rikuzen-Yokoyama Station opened on December 11, 1977. The station was absorbed into the JR East network upon the privatization of the Japan National Railways (JNR) on April 1, 1987. Operations were discontinued after the 2011 Tōhoku earthquake and tsunami. In 2018 the replacement bus rapid transit service was restored to a roadway on the former tracks.
