Volcano eruptions
Mount Aso is one of the largest volcanoes in the world - its caldera is 120 kilometers in circumference. An eruption 90,800 years ago released 600 km³ of lava and debris. An eruption of that size today would have devastating consequences that extend far beyond Japan's borders.
Mount Aso erupted in 2009 and 2011. Smoke is constantly rising from its giant water-filled caldera. The highest of its five summits reaches 1592 meters. Thanks to this volcano, the city of Aso provides hot springs and many attractions for tourists.
My Experience on Mount Aso
At the end of 2023 I had the chance to visit Mount Aso on my trip through the Kyushu region. First I went to the famous hot spring town of Beppu, then I booked a hotel in a small town called Taketa.
It was late fall, so it was quite cold, it was almost unbearable to stand on top of the mountain in that cold, unfortunately the smoke coming out of the volcano made it difficult to appreciate the crystal-clear waters present in some places on the peak.
All the sightseeing in the Kyushu region was wonderful, and seeing the volcano was also very exciting, but be aware of the cold, the hike and the bus timetable so that you don't fall behind.
