Yuda Kuei Onsen is set in Satsuma, Kagoshima Prefecture, Japan. The sodium-chloride thermal water reaches 39°C here. Indoor and outdoor (rotenburo) baths plus a sauna round out the facility.
Insider tip — 'Yuda Kuei Onsen' in Satsuma-cho, the historic heartland of ancient Satsuma Province in Kagoshima. The onsen sits in the forested Sendai River watershed where the Satsuma Domain's highland communities have farmed and bathed for centuries. The volcanic geology of the Kirishima chain supplies consistent thermal sodium-chloride waters to this rural inland area, far from the famous coastal onsen resort strips but no less valued by local communities.
