A Japanese onsen is a natural hot spring, often found in scenic locations across Japan. These geothermal springs are rich in minerals and are believed to have therapeutic properties. Onsens can be enjoyed in various settings, from public baths to private facilities, and are an integral part of Japanese culture and relaxation. Visitors to an onsen typically follow specific etiquette, such as washing thoroughly before entering the communal baths. Onsens are often accompanied by traditional ryokan inns, where guests can experience authentic Japanese cuisine and hospitality. The serene environment and warm waters make onsens a popular destination for both locals and tourists.
