Trains on the JR Shikoku Yodo Line also start from and end at Kubokawa although the official start of the line is the next station at Wakai. Kubokawa does not bear a station number with the "G" prefix which is used for stations on the Yodo Line.
The station consists of two side platforms and one island platform serving four tracks. Platform 1 serves a siding which is used exclusively by the Nakamura Line and is accessed from the Tosa Kuroshio Railway station building. Platforms 2 and 3 (which share an island) and platform 4 (a side platform) are used by JR Shikoku trains. These are accessed by a footbridge from the JR Shikoku station building or a level crossing. Several sidings branch off tracks 3 and 4. The JR station building houses a waiting room and a JR ticket window (Midori no Madoguchi). Car parking and a bike shed are available outside.[2][5][6][7]

The JNR Nakamura Line connected to this station on 18 December 1963 and the JNR Yodo Line on 1 March 1974. After the privatization of JNR on 1 April 1987, control of the station passed to JR Shikoku. The JNR Nakamura Line was privatized to the Tosa Kuroshio Railway on 1 April 1988.
