The castle consisted of two baileys, the Honmaru which was surrounded by a mizubori (water-filled moat) and the Ninomaru, which had the maintenance facilities; the Ninomaru was not surrounded by a mizubori but by mud wall like barriers separating the castle from the outside.
城の建物の構成は、水堀に囲まれた本丸と管理施設のある二の丸による2郭で、二の丸に堀はなく、土壁のような柵で城域を囲い、城内と城外を別けていた。
