Mount Aso Tourism

Mount Aso, situated in Kumamoto Prefecture on the island of Kyushu, Japan, is one of the world’s largest active volcanoes. Spanning 25 kilometers north to south and 18 kilometers east to west, Mount Aso encompasses a caldera with a circumference over 100 kilometers, formed by multiple enormous eruptions in prehistoric times. Within this massive caldera lie populated towns, lush farmlands, and Aso's five peaks, including the active Nakadake crater, which periodically emits smoke and has a picturesque, acidic crater lake with changing colors. Visitors can explore the outer rim, the verdant caldera floor, as well as Aso’s cultural and historical sites. The Aso Volcano Museum offers insights into the volcano's geology. The region's natural beauty is complemented by the distinct seasons it experiences, from bright green pastures in spring to the deep red hues of autumn leaves. Hiking, hot springs, and horseback riding are popular activities. Tourism is occasionally affected by volcanic activity, so it is essential to check for any restrictions before visiting.
