Onsen Café Agannasse
A full-service city spa for visitors who want natural hot spring bathing, outdoor pools, saunas and a place to unwind. It is less compelling for the cheapest possible short soak. Tattoos and imitation tattoos are not admitted, and renovation work currently affects some lounge areas.

How to read a bath profile
