Jukaku hot spring water
Sakurajima is one of Japan’s most active volcanoes.
Looking up to it, is the city of Tarumizu where jukaku water gushes forth from 800m underground. It contains 8.89ppb (parts per billion) of water-soluble germanium which is a hundred times more than the average.
Water-soluble germanium can also be found in plants such as ginseng, reishi mushrooms, polypores, or garlic and has been used for the longest time to maintain health. Natural alkaline ionized water, jukaku, is also rich in natural minerals and is known to have excellent penetrating and extracting power due to its unusually small molecular structure.
