Free-flow from source
Bath
A mildly alkaline sodium bicarbonate spring that bubbles up from 1,000m underground. Part of the open-air bath uses spring water directly from the source in free-flow style, allowing you to feel the rich natural minerals of the hot spring on your skin. It is well known as a bijin no yu, or beauty bath, that leaves the skin smooth, and even after bathing, your skin stays moist and warm for longer. This luxurious bathing space lets you enjoy a truly indulgent soak while gazing up at the Tochigi sky.
