"Mifune Terrace" is a brand-new hot spring and accommodation complex that has opened in Mifune Town, Kumamoto Prefecture. It boasts exceptional facilities shaped around the needs of sauna enthusiasts, with three rooms: a high-temperature dry sauna over 100°C, a meditation sauna where self-löyly is possible, and a mild steam sauna. The standout feature is a cold-plunge combination bath with two options: an ultra-cold bath set below 10°C in a "single" configuration, and a standard cold plunge bath at around 16°C. In the spacious outdoor cooling area, reclining chairs are lined up, allowing guests to fully enjoy the blissful totonou experience while bathing their whole body in the pleasant Kumamoto breeze.
