[3] In addition to the local trains of the Dosan Line, the following limited express services also stop at Sakawa Station:[4] The station consists of two opposed side platforms serving three tracks.

A station building houses a waiting room and a JR ticket window (without a Midori no Madoguchi facility) as well as a tourist information centre set up by the local municipality.

With the privatization of JNR on 1 April 1987, control of the station passed to JR Shikoku.

[3][7] On 4 March 2017, Sakawa town authorities opened a tourist information centre inside the station building using space offered by JR Shikoku.

The centre, which is unstaffed, features a custom-built information terminal about Sakawa town, maps and brochures, educational displays as well as a model of a local historic building.
