Miyao Castle (宮尾城 miyao-jō) was a fortification built on the island of Itsukushima (also known as Miyajima) during the Age of Warring States in Japan. Although referred to as a Japanese castle it did not have a donjon (tenshu) or serve as the residence of a land-holding noble and therefore is probably more within the definition of a hill fort rather than a true castle.
