Hiraname Falls
This falls is along the Tadamigawa River where it flows from the east edge of Osegahara northward. As its name (“smooth slide”) implies, it flows down 400 meters from a massive rock as if sliding down a hill. This shows that the river, which seems to at first glance to flow through a flat landscape, so that one cannot tell where it comes from, is actually flowing down a gentle slope. About a kilometer farther down the river is Sanjo Falls, chosen as one of the Japan's Top 100 Waterfalls. It appears to be more powerful than Hiraname Falls. Certain sections of the riverbank can be extremely muddy, so walkers need to be fully prepared.
