Saga Onsen Hizen Yumo — Scenic Mineral Spring Spa

Located 20km south of Saga City in the Sefurisan mountain range, Hizen Yumo Onsen is a concentrated cluster of three ryokan using the same source — a sodium chloride hot spring at 48°C that has been used since the 12th century. The spring water is amber-colored from the mineral content, and the outdoor baths overlook the Kase River valley from an elevation of 400m. In autumn (mid-November), the surrounding forest creates one of the finest foliage framing views of any onsen in Saga Prefecture.
