Ono Castle Ruins (Shiroyama Park)
大野城
Castle ruins in Tokoname designated a historic site and preserved as Shiroyama Park with a shrine honoring the Saji clan and scenic bay views.

In the year 1350, Nori Ichishiki, protector of Mikawa Province, expanded his power to the Chita Peninsula. His son, Noriatsu Isshiki, built a castle overlooking Ise Bay and took control of shipping in the area. Over time, the castle changed hands among various clans, including the Saji clan, who ruled the territory for over four hundred years. However, due to poor water management at Ono Castle, the castle became abandoned. Now, the main area is designated as a cultural property (historic site) in Tokoname City and is preserved as Shiroyama Park. The park features the Saji Shrine, which honors the Saji clan, the former lords of the castle. The observation deck of the castle offers breathtaking views of Ise Bay and the foot of Mt. Suzuka.
