TypeNatural Hot Spring
A sodium bicarbonate spring that gushes up from 1,000 m underground. The cloudy source water, ranging from ochre to yellow-green, is characterized by its smooth, silky texture. It is offered as free-flowing water straight from the source with no added water, and its rich mineral content makes it highly effective for warming the body. It is beloved as a "beauty bath" that helps remove unwanted dead skin cells, leaving the skin soft and moisturized after bathing. The amber-colored water and distinctive aroma create an authentic hot spring atmosphere.
