Onsen, or natural hot springs, are found throughout Japan. They are a popular destination not only among foreign tourists but the locals as well because of the many health benefits they provide. They contain minerals that help relax the mind, muscles, and entire body; the perfect place to go to for a day or weekend getaway.

There are various kinds of onsen — outdoors, indoors, mixed, and gender separated. Some are found in ryokan, or Japanese style lodgings, and others have their own buildings as public bath houses.

Onsen Etiquette

  • Remove all clothes and thoroughly wash your whole body with soap and water in the designated area before going into the hot spring.
  • When you are ready to get into the water, take a modesty towel and use it to cover your private parts if you feel self-conscious. Otherwise, just walk normally and be careful of slippery surfaces.
  • Do not jump or dive into the water. Slowly ease yourself into it.
  • Once in the water, place your modesty towel on your head or set it aside on a rock. It is considered rude to soak the towel in the water or wring it out.
  • Try to stay in a particular area of the onsen and not move around too much. Respect other people’s space. Do not swim.
  • Once you are done, get out of the water slowly and dry yourself with your towel before heading out to get dressed in the designated room.
