The station consists of an island platform serving two tracks at grade with a siding.

The station building is a wooden structure in western style with a stained glass gable.

It staffs the ticket booth which is equipped with a POS machine but does not have a Midori no Madoguchi facility.

With the privatization of Japanese National Railways (JNR), the successor of JGR, on 1 April 1987, the station came under the control of JR Kyushu.
