* Bath Preparation * Contains Dry Powder of a Natural Hot Spring Magma Onsen Bath Salts are made from the waters of the famous Umijigoku onsen (hot spring) located in Beppu, Japan. Umijigoku (translated as "Sea of Hell") is a famous hot spring located in Beppu – a coastal town in Kyushu Island. The waters of Umijigoku are created by the super-heating of water that has soaked through the fissures of the earth’s crust – often 100+ degrees Fahrenheit. Because the waters are blueish green and look like the color of seawater, the hot springs are called the “Sea of Hell.” Japanese women, and even men, rave about the product’s ability to smooth and soften the skin as well as provide a relaxing, soothing spa. A special blend of perfumes and fragrances are added to enhance relaxation.
