－Hot Spring Features－
The water for 'Saru-jin no Yu' originates from strata 1,500m to 2,119m underground. It is a precious blend of water from two different geological eras: approximately 5 million years ago (Cenozoic Neogene/Pliocene) and 54 million years ago (Paleogene/Eocene), which naturally mix as they rise to the surface.
It contains ancient fossil seawater from the era of one of the earliest humans, the Ardipithecus ramidus. While its salinity is about 80% that of modern seawater, it differs from regular seawater by being rich in metasilicic acid, calcium, iodine, iron, and various nutrients believed to be beneficial for skin, giving it unique hot spring properties.
This hot spring uses 100% free-flowing source water, without filtration, heating, or dilution, fully preserving the blessings of nature and allowing you to enjoy a pure, natural, and healing hot spring experience.
