Constructed in 1583, the castle is built on two raised platforms of landfill supported by sheer walls of cut rock. The central castle building is eight stories high inside and five stories outside. It was built on top of a tall stone foundation so that the occupants would be protected from sword-bearing attackers in the past. There are thirteen structures within the 60,000 square metres of the castle ground that have been designated by the Japanese government as Important Cultural Assets.
