Otodoro Falls, a Valley Cascade Chosen Among the 88 Views of Tokushima in Naka

In Naka town, Tokushima, Otodoro Falls hangs where the Sawatani River joins the Sakashu Kito River on the upper reaches of the Naka River. It is a three tiered cascade of about twenty meters dropping where the riverbed falls sharply away, and it is chosen among the eighty-eight views of Tokushima. Because it can be seen from along National Route 193, it is easy to stop by while driving. The bold rush of falling water, together with the roar echoing through the deep mountains, seems to wash the heart clean.

A little upstream stands Okama Falls, which is counted among the one hundred famous waterfalls of Japan. Visiting both together lets you fully enjoy the valley scenery of the Kamagatani gorge that represents Naka town.
