Onsen tourism refers to the practice of visiting natural hot springs, known as onsen, primarily in Japan. These hot springs are rich in minerals and are believed to have therapeutic benefits. Visitors often enjoy soaking in the warm waters, which can be found in scenic locations, enhancing relaxation and wellness. Many onsen facilities also offer traditional Japanese accommodations, known as ryokan, where guests can experience local cuisine and hospitality. Onsen tourism attracts both domestic and international travelers, contributing to the cultural and economic landscape of regions famous for their hot springs, such as Hakone and Beppu.
