In 1575, Nagachika Kanamori began to build a castle on Kameyama mountain, a small mountain in Ono County. It took several years to build the castle. After the Kazunori Aoki’s era, the Echizen Matsudaira family became a shogunal property, and the castle owner changed many times until the Doi family got it. The castle burned down in 1775 and was rebuilt in 1795 with the exception of the castle tower, but it was destroyed again after the Meiji Restoration.
