This site is one of the sites linked to the Momotaro tale. It is said that the demon Ura used this castle as the base from which he would pillage the nearby village, and its name which literally translates to "Demon Castle" was coined from the legend. As a historic site, it is believed to have been constructed between the 4th-7th century and is one of the oldest castles in Japan. Earthenware and walls remain, along with a reconstruction of the west gate. There is a free visitor center that acts as a small museum about the castle and its history with models and artifacts.
