Summary adapted from the Wikipedia article (CC BY-SA 4.0).
As a cascade waterfall, water tumbles down a series of rock steps rather than falling free.
No commercial adventures run at Nanataki Falls itself — the experience is the approach and the view. Guided day trips from Kosaka are the easiest way to combine it with the area around it.
