Tenjinyama Castle Ruins

Close to the Iwamuro onsen town, at an altitude of 234.5m, the remains of Tenjinyama Castle, where Naoe Kanetsugu's younger brother, Oguni Miyori (Yohichi Miyori), last served as a castle lord, still remains. It takes 20 minutes on a mountain trail from Marukan Park and 40 minutes on a paved forest road to the entrance of the castle ruins. As you climb further, you can enjoy the spectacular view from the Honmaru mark at the top of the summit, such as the observation stand, the earthworks, the stone base, the gourd pond, the gourd pond, and so on.
