"Tochigi Onsen Yuraku no Sato" is a super sento located in Tochigi City, known for its high-quality natural hot spring and well-equipped sauna facilities. The sodium bicarbonate spring that bubbles up from 1,000m underground is known as a bijin no yu, or beauty bath, because it helps remove dead skin cells and leaves the skin smooth. In the open-air baths, you can enjoy fresh water from the source poured directly from the spring. The sauna is a high-temperature dry sauna equipped with an auto-löyly function that automatically pours water at regular intervals. Powerful heat envelops your whole body and promotes excellent sweating. There is also a crisp cold plunge bath and a spacious outdoor cooling area with reclining baths, creating a well-rounded environment where both beginners and experienced sauna lovers can relax and refresh to their heart's content.
