Natural nigori (opaque) hot spring, which is flowing from the source

Onsen at Kohanyu is private golden source that is within our site and we offer it to you by flowing it from source luxuriously. This source is called an isotonic thermal spring water which is quite rare in Japan. Its mineral content is close to that of human skin cells, so it is said to be the healthiest and friendliest hot spring to human body. It is also rich in minerals and has smooth texture, therefore it is known that it has a remarkable effect to skin disease. So, it’s also known as a hot spring of beautiful skin.
