The Aso Region
The city of Aso, with its more than 30,000 inhabitants, lives in harmony with the volcano that bears its name. Past eruptions, although devastating, shaped the region and created an environment rich in natural resources, such as the hot springs that supply the various onsen in the city and its surroundings.
Aso Kujū National Park, which extends between Mount Aso and the Kuju Mountains, is a paradise for nature lovers. With its stunning volcanic landscapes, hiking trails, serene lakes, and relaxing hot springs, the park offers a complete experience for all the senses.
At the Aso station, a bus circulates from time to time to take tourists to the peak of Mount Aso; near the station, you will find a statue of the character Usopp from One Piece. In the neighboring towns, you can also find other ways to enjoy Mount Aso, such as a cable car and trails.
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 this size today would have devastating consequences that extend far beyond Japan’s borders.
Mount Aso erupted in 2009 and 2011. The smoke is constantly rising from its giant water-filled caldera. The highest of its five peaks reaches an altitude of 1592 meters. Thanks to this volcano, the city of Aso provides hot springs and many attractions for tourists.
My Experience at Mount Aso
At the end of 2023, I had the chance to visit Mount Aso during my trip to the Kyushu region. First, I went to the famous city of Beppu, known for its hot springs, then I booked a hotel in a small town called Taketa.
It was late autumn, so it was quite cold; it was practically unbearable to stay at the top of the mountain in that cold. Unfortunately, the smoke coming from the volcano hindered the enjoyment of the crystal-clear waters present in some places at the peak.
Every outing in the Kyushu region was wonderful; seeing the volcano was also quite exciting, but be aware of the cold, take a walk, and keep track of the bus schedules to avoid the danger of being left behind.
