Soaking in Japanese hot spring bath salts.

Most of us don’t have the luxury of visiting a Japanese hot spring whenever we choose. However, onsen bath salts enable us to enjoy the same relaxation and health benefits from home.

What are onsen/hot spring bath salts?

Onsen bath salts contain many of the same minerals found in the natural hot springs/onsens of Japan. The salts are added to your bathwater so that you can enjoy the benefits of a real hot spring which includes the soothing of muscle pains and helping with various illnesses – while also having a beautifying effect on the skin.

These are also extremely popular in Japan since most Japanese take hot evening baths to relax and soak in the minerals after a stressful day at work.
