We are proud of the quality of the water as well as the abundance of hot water, which is equivalent to seven drums per minute, and we always pour fresh water directly from the source without any circulation, water addition, or heating. The source of the water flowing out of the bathtub is breathtaking! All the bathtubs are naturally free-flowing, and all the showers and showers also use the source.
The self-spouting source of hot spring water that springs up on the premises, "Kanjuku no Yu," is a simple alkaline spring with a pH of 8.5 that is gentle on the skin.
