OnsenNatural Onsen

Chloride springs combine with sebum and proteins on the surface of the skin due to the salt components contained in the Onsen, forming a salt film.
The film wraps the skin like a thin veil on the surface of the skin, making it difficult for moisture and heat to escape from the skin, providing a moisturizing and heat-retaining effect that keeps the skin moist and warm.

Bedrock Saunatake a bedrock sauna

Bedrock sauna is a hot bathing health method that does not use water. You don’t have to worry about feeling suffocated because it’s not as hot as in a sauna, or feeling tingling on your skin or making your hair stiff.
Just by lying down comfortably, you will be surprised by the sweat that comes out of your whole body and you will feel refreshed.
The healing effect of negative ions generated from minerals is also well received.
