A smaller set of falls with a great shop at the base. The highlight is the walk that goes up behind the falls. A well made path with steps and seating. You get a great view of Lake Chuzenji on the way. If you got to the falls by bus (bottom bus stop) - you can wait for the next bus at the top of the falls - you do have to walk back down again. Vise-versa if you cam the other way.
Include on your exploration of the sights from Nikko to Yumoto-onsen. Easily fit in the falls and walk between buses.
