How To Take A Healthful Onsen Bath

Rinsing Off

Sit down and rinse your body with hot water using either a bucket or shower. It is the custom to remain seated when washing your body with soap. When first pouring hot water over your body, start pouring on places farthest away from your heart.


Rinsing off and washing like this not only helps to clean off sweat and dirt from your body, but it also lets your body get accustomed to the hot water, thus reducing the strain on your heart.

Wash Your Body

Wash your body thoroughly before bathing.

Enter the bath smoothly and quietly. Towels are not allowed in the bath. These days, more and more people enjoy sitting on the edge of the bath with just their feet in the hot water for a foot bath or ashiyu, while others sit in the water so that it goes just around the stomach area for a half-body-bath, or hanshinyoku.

Doing so also puts less strain on the heart, and yet still provides effective body healing benefits. The whole body can be warmed even if the whole body is not in the bath.

Whole Body Bath

After adjusting to the hot water by soaking your legs and lower body, you can fully enter the bath.
