Free-flow from source
Izumo Ekimae Onsen Lamp no Yu
A natural hot spring pumped up from a vein 1800 meters underground, an iron-rich calcium-sodium chloride spring. As the iron comes into contact with the air, the water changes to a golden-brown to brownish color, and the minerals are so concentrated that deposits build up in the bath itself. Because the source temperature is about 27°C, it is heated to around 42°C, and a small amount of chlorine is added for hygiene, but it is basically offered as free-flowing water. With a distinctly salty, iron-rich feel, it has long been loved for benefits said to help with anemia, menopausal symptoms, neuralgia, and recovery from fatigue. Please note that towels may turn brown.
