[5] Tosa-Ōtsu Station, which is unstaffed, consists of two opposed side platforms serving two tracks.

A small building linked to one of the platforms serves as a waiting room.

At that time the station was operated by Japanese National Railways (JNR).

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