While planning a future Japan tour, you may have heard about onsen. These natural hot spring baths are popular retreats for Japanese citizens and tourists alike. If you're interested in stopping by one on your trip, learn more about what the visit will entail and how to ensure you have a pleasant experience. 

What Are Onsen?

Onsen literally translates to “hot water spring.” They're used for communal bathing experiences and can be inside or outdoors. There are over 3,000 onsen in Japan visited by about 137 million people yearly. 

The water in an onsen is heated underground and must be at least 77° F. To qualify as an onsen, it should contain at least one of 19 chemicals that occur in hot spring water. These chemicals are beneficial for the body and help create a relaxing environment. 

What Are the Onsen Rules?

Onsen enforce a number of rules to preserve the facilities and everyone's comfort. Most onsen are divided with a curtain. The women’s side is marked in red, while the men’s side is marked in blue. Westerners may be surprised to learn that visitors are expected to bathe nude. While this might seem intimidating, the locals are accustomed to using public bathhouses, and the soothing water will soon ease any doubts you have. 

Tattoos are strictly prohibited in many onsen. In Japan, tattoos are associated with organized crime called yakuza. If you have a small tattoo, you can cover it up with a bandage. If your tattoos can’t be covered, you might need to rent the baths by yourself or find a tattoo-friendly onsen.

Shower before getting in the water, which keeps the onsen clean and sanitary for everyone. The facility will supply soap and shampoo, and you’ll sit on a stool while you clean yourself. 

When in the water, don’t dunk your head. If you have long hair, tie it up so it doesn't touch the water. While onsen are social places, keep your voice down to maintain the relaxing atmosphere. Cameras are strictly prohibited to protect the privacy of the bathers, so enjoy the moment without trying to post on social media.
