Insider tip — 'Kumairi Onsen Center' (熊入温泉センター — bear-entry spring center) in Yamaga city. 'Kumairi' (bear entry) is a place name with roots in ancient Japan when bears roamed the forests of the Yamaga highlands. The bear (kuma) is a sacred animal in Japanese folk religion — its entry into a place was considered a powerful omen. Yamaga's famous thermal waters emerge alkaline and skin-conditioning from the Kikuchi River's volcanic aquifer system. The community center here serves the farming and lantern-craft communities of this distinctly traditional Kumamoto city.
