Mount Aso

Mount Aso (阿蘇山, Asosan) in central Kyushu is an awe-inspiring active volcano with a caldera that ranks among the largest in the world. Its diameter stretches up to 25 kilometers, and its circumference spans over 100 kilometers. The volcano’s center features several volcanic peaks, including the accessible Nakadake, known for its spectacular crater. While the crater provides breathtaking views, it's important to note that the area is often closed off due to dangerous gases, volcanic activity, or bad weather, so checking conditions beforehand is crucial.

In addition to the crater, visitors can explore hiking trails that lead to Nakadake Summit—offering 350-meter high views of the surrounding volcanic landscape. A scenic plain called Kusasenri lies nearby, where visitors can enjoy horseback riding and easy walks. You’ll also find the Aso Volcano Museum, offering insights into the area’s volcanic history. For a more challenging adventure, take the trail to Komezuka, a beautiful volcanic cone, though access can be tricky. Mount Aso is a must-see for adventurers and nature lovers, offering both exciting hiking and serene landscapes.
