Sunamushi Onsen (Saraku), in Ibusuki, Kagoshima Prefecture, is fed by thermal water at 50°C (pH 7.3). The venue offers an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Ibusuki's famous sunamushi (sand bath) is among Japan's most unique thermal experiences: attendants bury you in naturally geothermally heated beach sand while you wear a yukata. 10–15 minutes is sufficient — the effect on circulation and fatigue is remarkable. Book Saraku in advance during Golden Week.
