Kakunodate Castle

Kakunodate Castle (角館城), also known as Asakura Castle and Ryugasaki Castle, was a mountaintop castle (yamashiro) located in Kakunodate, Akita Prefecture, Japan. Its roots can be traced to when Moriyasu Tozawa was given the area in 1590, though it may have been constructed prior to this. Due to a Shogunal decree that each domain was to retain only one castle, it was demolished in 1620. Only ruins remain at the site on Mount Furushiro.
