Yunogo Onsen (湯郷温泉, Yunogō Onsen) or simply Yunogō is a hot spring town located in Mimasaka city of Okayama Prefecture, Japan.
[1] The waters are said to have healing effects on those suffering from chronic digestive disorders, nerve pain, rheumatism, arthralgia, chronic feminine problems, and skin problems.
[2] 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.
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.
