Kusatsu Onsen (草津温泉) is a naturally heated spring which discharges from the ground at a total of 32,000 L/m from more than 100 points across the area. It is one of Japan's top three onsen and is world famous for it's therapeutic properties. The water is high in sulphate, aluminium, sulfur and chloride which gives it a unique green glow. Heated by underground volcanic vents the water reaches 60 ℃. The water is good for the relief of neuralgia, muscle pain, dermatosis, bruising, sprains hypertension and fatigue. The strong sterilising power, which destroys germs and bacteria, is the secret to it's therapeutic properties.
