Naranosako Onsen
A natural hot spring using water from Naranosako Onsen, which springs from underground in Kumamoto City. The alkaline simple weak radioactive hot spring has a soft texture and is gentle on the skin. Enjoy the source spring in both the indoor and open-air baths, and after the sauna, warm up slowly in the hot spring to deeply relieve fatigue. The open-air bath is located on the top floor, allowing you to enjoy a liberating bath while gazing at the Kumamoto sky. The bathhouse interior, inspired by the stone walls of Kumamoto Castle, offers a sense of the unique atmosphere of a tourist destination. After bathing, enjoy a pleasant time with ice cream and lactic acid drinks available at the post-bath area.
