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.
ASONIWA, an interactive kids' park where you can experience the nature of Aso, has opened!
Following its renewal on October 24, 2025, KAMENOI HOTEL Aso has opened a new "Kids Park" where children can learn about the great nature of Aso in a fun way.
With the design motif of the "grassland", which can be said to be the symbol of Aso, this is an experiential space where they can learn through physical activities. It is a kids' park where children can learn through play, nurturing their curiosity and desire to explore through playground equipment themed around the nature, creatures, and topography of Aso.
Renovated in October 2025.
The hotel has completed a luxurious room with a private open-air bath and sauna, as well as a kids' room with a terrace where families can enjoy laughter.
You can choose a unique experience in Aso that suits your travel purpose and mood.
