"Daifunto," the major tourist spot of Koan-kyo Onsen, is located in a V-shaped valley created by the rapid flow of the Minase River. When you descend the rocky staircase, you can walk along the promenade and see the intense eruption of 98℃ hot water and steam up close. Daifunto is a powerful geyser that erupts hot water and steam from cracks in the geothermal reservoir layer, with a temperature of about 98℃ and white cloudy hot springs flowing out. It is known as one of the specialties of Koan-kyo and can be considered the main attraction. Koan-kyo is rich in nature, and especially Daifunto is worth visiting for its powerful scenery.
