Kanagawa Yokohama City
An ultimate spa with natural hot spring water bubbling up from 2,000 meters underground and three kinds of carbonated baths
"Yokohama Spa Hills Ryusenji no Yu" is a day-use hot spring facility in Asahi Ward, Yokohama, Kanagawa Prefecture. It offers a wide variety of 15 baths, including natural chloride spring water drawn from deep underground, along with signature high-concentration carbonated baths and carbonated relaxation baths for dozing off. The sauna area features a powerful Bazooka löyly sauna that unleashes intense waves of heat, a medi sauna for men, and an aromatic salt sauna for women. After the sauna, you can cool down all at once in the icy extra-cold cold plunge bath. In addition, the expansive bedrock bathing lounge, forest villa, includes more than 15,000 books and a work space, creating a blissful place where you can relax to your heart's content all day long.
A sodium-chloride spring bubbling up from 2,000 meters underground. It is isotonic, so it is gentle on the body, and its mildly alkaline, soft texture is a defining feature. Because the salt wraps the skin like a veil, it retains heat well, and the warmth lingers long after you get out of the bath.
A blissful dozing-off bath where you can enjoy carbonated water while lying back comfortably. Wrapped in the soothing warmth of the water and carbonated bubbles, you can experience a deep sense of relaxation so calming that you may drift off to sleep.
A rainbow carbonated bath with a striking, fantastical lighting display. While watching the beautiful colors change over time, you can enjoy the pleasant stimulation of the carbonation. It offers a truly out-of-the-ordinary bathing experience that soothes both sight and touch.
A shallow, warm bath exclusively for small children who are still not out of diapers. Using natural hot spring water, it is designed to be family-friendly, allowing parents and children to enjoy a leisurely bath together while watching video content on a monitor.
The facility's signature carbonated bath, artificially infused with a high concentration of carbon dioxide gas. When you soak in the water, fine bubbles envelop your entire body, delivering a pleasantly sparkling sensation. With a mildly warm temperature setting that places little strain on the body, you can slowly loosen both mind and body over an extended soak.
A full-fledged dry sauna distinguished by automatic löyly that activates at 00 and 30 minutes every hour. The moment water is poured onto the sauna stones, powerful waves of heat burst into the room like a bazooka. The overwhelming heat that envelops your entire body draws out a huge amount of sweat in an instant. In the spacious interior, you can fully enjoy a dynamic sweating experience.
A men-only medi sauna where you can take your time facing both body and mind. In a calm space wrapped in silence, you are led away from the noise of everyday life into a deep meditative state. Comfortable heat and humidity gently warm the body, allowing you to enjoy an ultimate time of relaxation.
A women-only salt sauna filled with a pleasant aroma. By applying salt to the body and slowly sweating, it helps wash away dead skin cells and impurities from the pores. Wrapped in gentle heat and fragrance, it offers a blissful beauty experience that leads to smooth, hydrated skin.
