The station consists of two
side platforms serving two tracks at grade. The station building is a modern functional concrete structure which houses a waiting area and a staffed ticket window. Access to the opposite platform is by means of a level crossing. A bike shed is provided outside the station building. Management of the station has been outsourced to the JR Kyushu Tetsudou Eigyou Co., a wholly owned subsidiary of JR Kyushu specialising in station services. It staffs the ticket window which is equipped with a
Midori no Madoguchi facility.
