Yunogo Onsen
History. Yunogo Onsen is known as “Sagi no-yu,” or hot water of the heron (sagi is the Japanese word for egret or heron) because 1,200 years ago a Buddhist high priest named En-nin-houshi discovered an injured heron bathing its wounded leg in the waters of a hot spring in Yunogo. This is how the special healing powers of these waters were discovered, and they now have evolved into a spot where people come to relax and enjoy the waters. There is a statue of En-nin with a heron outside of the “Yunogo Sagi Onsen -kan,” the public bathhouse created in the exact spot where the heron's hot spring was discovered. Access.
