Mooka Igashira Onsen
A colorless, clear natural hot spring that springs from deep underground. It is a fossil-water-type hot spring in which ancient seawater has been trapped in the strata, and it is characterized by a strong salt content similar to seawater. Because it has high permeability, it warms the body very quickly, and after bathing, the salt coating on the skin helps retain heat, delivering outstanding heat retention and moisturizing effects. You can enjoy it luxuriously in the spacious indoor bath and open-air bath.
