The two lines serving the station intersect at Orio, and the lines are connected by a spur track. The station therefore consists of two separated blocks: the main building with bi-level platforms at the crossing point, and detached platforms on the spur.
The station building was rebuilt in 1916, but use of this building was discontinued from 6 October 2012 in preparation for rebuilding work, with operations shifted to a temporary structure. The station building is scheduled to be demolished during 2012, with the new structure completed in fiscal 2016.
Airport buses leave from a bus stop located at the west exit of the main building to the Kitakyushu Airport. Also, there is a Kitakyushu municipal bus terminal for local buses connecting vicinities including Wakamatsu and Ashiya in front of the east exit of main building.
