[2] Access to the island platforms is by two underground passageways connecting them with the station building.

A footbridge known as the Rainbow Bridge spans the station plazas to the east and the west of the tracks and is also served by elevators.

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

The new building will be a hashigami structure in which the station facilities would be located on a bridge spanning the tracks.
