DIY Onsen Experience
The name 'Sunayu' literally translates to 'sand hot water,' referring to the phenomenon where hot spring water bubbles up just beneath the sand, letting you dig a perfect natural footbath.
Swan Sanctuary
During the colder months, Sunayu Onsen becomes a spectacular gathering spot for numerous whooper swans, who are drawn to the warm waters of the lake, creating a beautiful contrast with the snowy landscape.
