About Miurayu
"Miurayu" is a natural hot spring facility located under the elevated tracks of the Keikyu Line in Minami Ward, Yokohama, Kanagawa Prefecture. Its 100% natural spring black bath, known as "kuroyu," gushes up from 150 m underground and is characterized by its smooth, viscous feel and sodium bicarbonate spring quality, which is said to be highly effective for beautiful skin. The "kuroyu carbonated spring," made by dissolving carbon dioxide into this black bath, is a popular tub where you can enjoy both the benefits of the hot spring and improved circulation at the same time. The sauna area is equipped with a far-infrared tower sauna using bakuhanseki and a soothing mist sauna wrapped in fine vapor. Because the men's and women's baths switch every Monday, you can also enjoy 14 different baths with a variety of atmospheres that change from week to week.
