Kikuchi Wakuwaku Onsen is located in Kikuchi, Kumamoto prefecture. Its sodium-chloride water reaches 41°C and feeds an indoor bath as well as an outdoor rotenburo, with an on-site sauna.
Insider tip — In Kikuchi, home to the breathtaking Kikuchi Gorge where ancient beech forests hang over a series of cascading waterfalls along a UNESCO-recognized Globally Important Agricultural Heritage landscape, Wakuwaku Onsen (exciting/thrilling spring) captures the exhilaration of Kikuchi's natural abundance; after gorge hiking among pristine forest, the mineral spring recovery is thoroughly earned.
