Hot springs, also known as onsen, are a common and popular feature of Japanese culture and society. Onsen are natural hot springs that are believed to have therapeutic properties, and they can be found all over the country, particularly in mountainous areas. They range from basic, rustic bathhouses to high-end, luxurious resort-style spas, and are often surrounded by scenic landscapes, making them popular tourist destinations. Onsen are a social and cultural experience as well, with many following strict etiquette and traditions, such as nudity and washing before entering the hot spring.
