It was a simple structure from the outside, but inside were endless passages, connecting rooms, trick doors, hidden rooms, and subterranean chambers. A frequent host for regional winter courts the building overlooked all of Ryoko Owari and was second in size only to the Temple of Daikoku. It was the first Governor's residence. The top of the palace was the highest spot in Ryoko Owari.
