Japanese onsen baths are natural hot springs that are popular across Japan. They have been around since ancient times and are believed to have therapeutic and medicinal benefits. Onsen baths come in many varieties, indoors and outdoors, traditional and modern, and are often found in scenic locations such as mountains, forests, and coasts.

To enjoy an onsen bath, one must follow some etiquette rules. First, one must enter the bath completely naked, without any swimsuit or clothing. Second, one must wash and rinse their body thoroughly before entering the bath, using a small towel and a shower. Third, one must avoid letting their hair or towel touch the water of the bath, as this is considered unclean. Fourth, one must respect the privacy and comfort of other bathers, by not staring, talking loudly, or using cameras or phones.

Onsen baths are a great way to experience Japanese culture and relax. They can be enjoyed at ryokan (traditional inns), hotels, or public bath houses. Some famous onsen destinations include Kusatsu Onsen, Hakone Onsen, Kinosaki Onsen, Beppu Onsen, and Kurokawa Onsen. Onsen baths can also be recreated at home by using hot water and onsen bath salts.
