Recommended points!
Our Hot springs contains 142.0mg/L, a natural ingredient that protects skin hydration and elasticity.
Silica (metasilicic acid) meets the standard of "hot spring for beautiful skin" at 100mg/kg or more, and bathing moisturizes the skin and leads to a moist and smooth feel.
Surrounded by the great outdoors of Aso, soak in the abundant silica-containing hot waters and enjoy a luxurious "skin beautification experience" that can only be experienced here.
