Beppu, located on Japan's Kyushu Island, is renowned for its extensive hot spring resources, boasting the largest volume of hot water and number of hot spring sources in the country. The city is divided into eight distinct hot spring areas, called "Beppu Hatto," each offering unique thermal experiences. Visitors can indulge in various types of baths, providing a comprehensive wellness retreat.

One of the most unique attractions is the "Hells of Beppu," a collection of spectacular hot springs meant for viewing rather than bathing. These geothermal wonders showcase vibrant colors and unique features, offering a glimpse into Earth's geothermal activity.
