The Onsenkan Kiyora center, in Minamioguni, Kumamoto Prefecture, draws on sulfurous thermal water at 43°C with a pH of 6.5. The facility includes an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — 'Onsenkan Kiyora' (温泉館きよら — pure/clear hot spring hall) at Minamioguni's community exchange center. 'Kiyora' (清ら) is an archaic Japanese word for purity and clarity, suggesting waters as clear and bright as spring light. Despite the sulfurous volcanic energy of the Waita zone, Minamioguni's community spring presents its thermal offering as clarity and purity — the mountain water distilled by volcanic heat into something essential. This municipal facility is the social heart of a small Kumamoto town at Japan's active volcanic frontier.
