Hisuikyō

Hisuikyō is a canyon carved by the Hida River in Kamo district, with sheer rock walls and countless rounded basins etched into the stone. The river has gradually deepened these potholes, creating a distinctive landscape of eroded rock formations that defines the area.

The canyon formed over millions of years through river erosion and contains rocks approximately 2 billion years old. These ancient geological formations represent some of Japan's oldest known stone.

The canyon stands as a designated National Natural Monument since 1961, reflecting the geological heritage and natural phenomena of water erosion patterns.

The canyon can be reached through a short walk from nearby rail access, with parking space available for visitors. Wear sturdy shoes as paths become wet and slippery near the river.

The canyon features remarkable swirl holes carved by water vortexes spinning round and round within the hard stone. These perfectly rounded depressions showcase the precise and powerful work of water over geological time.
