Ichinowatari Station (一の渡駅, Ichinowatari-eki) is a railway station on the Sanriku Railway Company’s Rias Line located in the city of Miyako, Iwate Prefecture, Japan.

Ichinowatari Station is served by the Rias Line, and is located 98.2 rail kilometers from the terminus of the line at Sakari Station.

On 1 April 1984, upon the privatization of the Kuji Line, the station came under the control of the Sanriku Railway Company.

During the 11 March 2011 Tōhoku earthquake and tsunami, part of the tracks and the station building at Shimanokoshi were swept away, suspending services on a portion of the Sanriku Railway.

However, the portion of the line from Miyako to Tarō resumed operations on 20 March 2011.
