So What is An Onsen?
Onsens, as they are called in Japan, are naturally occurring volcanic hot springs that have become part of the country’s rich culture. In Niseko, they offer a welcome relief to strained muscles after a long day of hiking or skiing and is something you should definitely not miss during your visit.
Not every onsen is the same, as the water varies widely in terms of mineral composition based on its location, and the path through which it traverses. Besides providing a sense of relaxation, the mineral-rich water also offers a plethora of health benefits for its fortunate bathers.
Onsens in Japan can be private, public, gender-exclusive, or mixed. Regardless of which one you choose, the basic principle remains the same. You remove clothing, wash your body, and get into the hot water to let your body soak. The onsen culture in Japan fosters the egalitarian principle that says ‘once you strip of all material possessions, every individual is equal’.

Health benefits of Bathing in an Onsen

Interestingly, the Japanese categorize and associate the onsens with different health benefits based on the minerals found in water. For example, if the water contains sodium bicarbonate saline, the onsen is good for the skin; if it contains high amounts of sulfur, it is good for treating high blood pressure and joint pain. Here are some of the common minerals found in the hot spring water and their benefits:
- Sodium Bicarbonate saline makes your skin smooth and radiant
- Sulfur reduces high blood pressure and joint pain
- Chloride maintains body heat
- Sulfate heals cuts and bruises
- Ferruginous improves iron level in the body
- Carbon Dioxide controls conditions like high blood pressure and rheumatism
Japanese scientists have been studying the impact of hot springs on human health since the 18th century. Decades of research and documentation have shown that soaking in onsens can help people recover from different health conditions such as neuralgia, rheumatism, hypertension, and skin diseases.
Hot springs have a physiological mechanism that maintains the body temperature at a certain level, which is not achievable with plain tap water. It’s no wonder that a large number of international tourists visit onsens in Japan every year.

Etiquette to Observe When Bathing in An Onsen
Communal onsen bathing is weaved into Japan’s way of living for centuries and the practice comes with a closely observed set of customs. To experience these gifts of nature, we should all know how to share it with respect for one another and for nature itself.
First of all, is cleanliness. Everyone is expected to wash thoroughly before entering the water; that is what the shower areas are for.
Normally, male and female are segregated into different bathing areas or by different bathing schedule. So make sure that you know where and when you belong. For women, onsen bathing during menstrual periods is highly discouraged.
Next, you have to be ready to remove all your clothing, no exception. You will be provided with a small towel which you could use in covering your privates when walking to and from the changing room, but it is important not to allow any linen to touch the water.
Once you are in the water, find a comfortable position and refrain from moving about. Just stay still and savor the experience at peace. Feel free to submerge your body all the way to your neck, but please do not dip your head into the water especially your hair. Tie your hair neatly before entering the water.
Many onsens also do not allow people with tattoos to bathe, but you can try to ask for a private bath or a private session. You may be tempted to take a selfie to share your experience with everyone at home. But for obvious reasons, you have to resist the thought, unless you are enjoying a private bath.
