Ōno Castle

Ōno Castle sits on Miyayama hill in Tokoname and displays the structure of a medieval Japanese fortress with stone walls and foundations clearly visible. Walking paths guide visitors through the compound, revealing the layout and defensive features of the site.

The fortress was built during the Sengoku period as a defensive position to control Owari Province and its strategic waterways. It became significant in the territorial conflicts of that era before eventually being abandoned.

The castle served as a control point for regional trade and movement across the bay waters. Today, walking through the site lets you see how its elevated position made it essential for monitoring the surrounding lands.

The site is walkable and the hilltop offers natural viewing points over the bay. Wear comfortable shoes since the terrain is uneven and there is ground to cover while exploring.

On clear days, the location offers views across Ise Bay and toward the Chita Peninsula. This extended sight line was exactly why this spot held such value for monitoring sea routes.
