200 years of history since it’s discovery, the onsen contains 2 spring qualities. The source of the onsen which we draw our hot water from is Mount Myoko, one of the nihonhyakumeizan (One hundred famous mountains of japan). From Mount Myoko there are multiple sources of hot springs which lead into one pipe that comes down to Akakura, then into our onsen. The onsen water is straight out of the source form Mount Myoko making our onsen unprocessed and natural containing many minerals which you can directly see in the onsen. Please enjoy your true onsen experience at our hotel.
