Located in the picturesque town of Yufuin, Oita Prefecture, Japan, Yufu Onsen is a historic hot spring resort famous for its rich thermal heritage. Soak in the warm, bicarbonate-rich waters and relax in a serene atmosphere. This traditional onsen offers a tranquil escape from the hustle and bustle of daily life. Discover the natural beauty of Kyushu's southern region.
Insider tip — Yufu Onsen sits at the foot of the twin-peaked Mount Yufu volcano in Oita Prefecture, where milky sulfurous waters emerge at scorching temperatures above 80°C and must be cooled before bathing. The town of Yufuin is renowned for its refined ryokan culture, and the morning mist rising from the river of hot springs creates one of Kyushu's most iconic landscapes. Arrive before 8 a.m. to enjoy the quiet open-air baths before day-trippers flood in from Beppu.
