Recommended points!
Our hot spring contains 142.0 mg/L of silica (metasilicic acid), a natural ingredient that protects the skin's moisture and elasticity.
Silica (meta silicic acid) meets the criteria for being considered "hot water for beautiful skin" at 100 mg/kg or more, and bathing in it moisturizes the skin and makes it feel moist and smooth.
Surrounded by the magnificent nature of Aso, immerse yourself in these silica-rich waters and indulge in a luxurious “skin-beautifying” experience that can only be enjoyed here.
