[1] It is one of "Japan’s Top 100 Waterfalls", per a listing published by the Japanese Ministry of the Environment in 1990.

The falls were created by a large-scale pyroclastic flow caused by a volcanic eruption that occurred 9 million years ago, creating a cliff of tuff with the river flowing from three sides of the cliff.

Downstream, there are many potholes on the riverbed, with a maximum size of six to seven meters in the long axis, and there are two smaller waterfalls.

The falls were used as a backdrop image for the opening credits of the 2000 NHK Taiga drama Aoi.

The falls can be reached in about 30 minutes by car from the Numata Interchange on the Kan'etsu Expressway.
