Hot spring

CONCEPT Soak in the finest hot springs,
A moment of bliss

It is said that alkaline hot water has a pH of 7.5 or higher, which has a skin-beautifying effect, but Kashoen's hot water boasts a pH of 9.0 .
The water is gentle and allows the water to easily penetrate the body, so you can take a bath as many times as you like, and enjoy both the indoor bath and the open-air bath made of cypress.
