Although the waterfall is only 10 meters high, it is 20 meters wide, and the water that falls like a curtain is illuminated by the sunlight through the trees.

This waterfall, which is said to have been created by a huge eruption about 90,000 years ago when the Aso caldera was built, has been transformed into its current form over the years.

The hard bedrock above the waterfall and the soft stratum behind the waterfall are still undergoing repeated erosion and changing their shapes little by little.

In spring, there is an event to light up the waterfall from the back for a limited time.
