One of Japan’s premier skin-beautifying springs and a crisp, exceptional cold plunge bath
Miyazaki Misato Town
Located in the mountains of Misato, Nango Onsen Yamagiri (Dontaro no Yu) is a nationally acclaimed hot spring. Its alkaline sodium bicarbonate spring boasts a pH of 8.7 and delivers an exceptionally silky, smooth skin feel the moment you enter. Beyond the outstanding onsen, the sauna facilities are also top quality. Warm up slowly in the dry sauna, then plunge into a crisp, cold plunge bath. The cold plunge bath feels very soft and pleasant on the skin. The outdoor area features infinity chairs and benches, allowing you to enjoy Misato’s clear air and mountain views while achieving a perfect totonou (state of perfect relaxation).
