Chihara Onsen (hot spring) is a therapeutic bath facility that opened approximately 100 years ago.
This hot spring has been noted as being effective at treating burns, cuts, and skin diseases, and many sufferers have been treated here.

This hot spring is hidden deep in the mountains and can only be reached by car. It is a rare type of spa, even in Japan, where you can appreciate spring water that comes directly out of the earth.
You can take the hot spring water home with you and pour it into your own bathtub. It has such a high concentration that the potency remains the same. People come from long distances away to fill up their containers with hot spring water from this spa.

The spring water is mildly hot, and the bubbling hot water and the high potency of the elements help your body warm up from the inside.
