Arima Onsen is one of the three major hot springs in Japan.
It features two hot springs, Kinsen and Ginsen.
Kinsen features red copper-colored hot water.
At the moment it springs out, it is colorless and transparent, but when the abundant iron ions contained in the hot water touch the air, the color changes to a rusty iron.
The salt contained in Kinsen has the effect of keeping the body warm, such as low back pain, joint pain and poor blood circulation.
The color of Ginsen is colorless and transparent.
Ginsen, in which carbon dioxide is dissolved in hot water, expands blood capillaries and promotes blood flow. Therefore, it is considered effective for vascular symptoms.
