Shizuoka Numazu City
"Numazu Yugawara Onsen Manyo no Yu" is a 24-hour bathhouse in Numazu City, Shizuoka Prefecture. You can enjoy natural hot spring water brought in daily from Yugawara in an open-air bath with views of Mt. Fuji. The sauna area features two types of saunas: a high-temperature dry sauna equipped with powerful automatic löyly, and a herbal steam sauna with a soothing monthly-changing fragrance. The cold plunge bath, filled with refreshing groundwater pumped up from 70 m underground, is located in the open-air area, and the smooth flow into the outdoor air bath area leads to a high-quality totonou experience.
TypeNatural Hot Spring
Natural hot spring water brought in daily by tanker truck from the famous Yugawara Onsen. It has a sodium-calcium chloride-sulfate spring quality and is highly regarded for its skin-beautifying effects and fatigue recovery. Also known as a "hot spring that stays warm," it is hard to cool down after bathing, and the skin feels moisturized and well-conditioned, with a lingering warmth from deep within that lasts for a long time.
Sauna TypeDry Sauna
Stove Typeconvection
Capacity20people
A spacious sauna room that prides itself on automatic löyly activated every hour on the hour. The sudden rise in humidity from löyly wraps your whole body in powerful heat, with a perceived temperature of nearly 100°C. Whether you relax while watching TV or take in the waves of heat with your entire body, you can enjoy a premium sweating experience unique to Manyo no Yu.
Sauna TypeSteam Sauna
A low-temperature, high-humidity steam sauna that soothes you with the monthly-changing scent of herbs. Gentle steam fills the room, allowing you to work up a good sweat slowly while keeping strain on the body to a minimum. The aromatic effect of the herbs is excellent as well, making this an ideal healing space for sauna beginners or anyone looking to unwind at a leisurely pace.
