Rich in sodium, it warms your body gently and deeply from within. Meanwhile, the open-air bath is filled with the colorless, transparent, smooth, skin-beautifying "Shiro no Yu," which gushes from about 2,000 m underground, allowing you to enjoy two natural hot spring sources to the fullest while feeling the breeze from the lake. Twice the enjoyment, twice the luxury.
