Shukunobe no Yu
A natural hot spring with sodium bicarbonate spring water. Its mildly alkaline, hypotonic water is gentle on the skin and helps remove dirt and dead skin cells, which is why it is cherished as a beauty bath. In the open-air bath, it is luxuriously provided as source-fed water, allowing you to feel the power of the fresh spring while taking in the rich natural scenery of Onuma. After bathing, your skin feels moist and smooth, offering a soothing sense of relaxation for both body and mind.
