Minara Tennen Onsen Riraku

A large day-use bathing complex fed by two of its own springs pumped up from deep underground, with eleven or more different bath and sauna facilities under one roof. The open-air area has a cave-like bath lit blue where the water is kept lukewarm for long half-body soaks and conversation, a similarly mild rock bath, a jet bath, and a walking bath, while the indoor hall draws on both springs at once. The men's side has a dry sauna with an automatic steam release; the women's side, a low-temperature, high-humidity steam sauna. A cold bath is fed by spring water from the Toon Alps (東温アルプス) and stays just as cool year round. The water itself feels soft on the skin. Beyond the baths there's a restaurant open even to non-bathers, a rest lounge, and private family baths you can book by phone. An outdoor deck looks out over the same mountains and the fields below.
