Oboke Gorge (大歩危, Ōboke) and neighboring Koboke Gorge (小歩危) a little ways downstream, are narrow, steep sided gorges near the entrance to the Iya Valley and popularly combined with a visit there. Cut by the swirling rapids of the Yoshino River, their names mean "big dangerous steps" and "small dangerous steps" as their jagged, rocky walls can be perilous to navigate.

The gorges are one of the leading outdoor destinations in Japan, rivaling Minakami in Gunma Prefecture, and are known for their beautiful natural scenery and for the variety of outdoor attractions, such as whitewater rafting and canyoning, that can be enjoyed on the river.
