Shiratori Onsen Geto Yu, in Ebino, Miyazaki Prefecture, offers sulfurous thermal water at 42°C with a pH of 6.5, an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — 'Shiratori Onsen Geto Yu' (白鳥温泉下の湯 — white bird spring, lower bath) — the companion facility to Joto Yu at the famous Shiratori Onsen on Ebino Plateau. The lower bath (geto, 下の湯) typically offers a different pool configuration than the upper bath, but shares the same powerfully sulfurous volcanic spring — white-turbid, heavy with hydrogen sulfide, direct from the Kirishima volcanic system. Shimoedake's last major eruption (2011) was visible from this plateau. Bathing in the volcanic landscape it produced is a humbling experience.
