History
Iwaizumi-Omoto Station opened on 1 April 1984 as Omoto Station (小本駅) on the Sanriku Railway North Rias Line, serving what is now the town of Iwaizumi in Iwate Prefecture. During the 11 March 2011 Tōhoku earthquake and tsunami a portion of the trackbed and the station building at neighbouring Shimanokoshi were swept away, suspending services on a section of the Sanriku Railway; the section from Omoto to Tarō reopened on 29 March 2011 and the section from Omoto to Tanohata reopened on 6 April 2014. On 27 December 2015 the station was renamed Iwaizumi-Omoto at the request of the town, which had been left without any "Iwaizumi"-named station after the 2014 closure of the JR East Iwaizumi Line. On 23 March 2019 it became an intermediate station of the consolidated Rias Line.

Notes
The staffed station building doubles as the Iwaizumi Disaster Relief Centre and the Iwaizumi Tourist Information Centre, reflecting its role as the town's public-facing transport hub after the 2014 closure of the JR East Iwaizumi Line.
