Create an itinerary including Mt. Aso
The largest volcano in Japan and one of the largest in the world, Mt. Aso holds a ferocious reputation, its natural power a major influence on the surrounding landscape. The volcano's peak reaches a height of 1,592 m (5,223 ft), its ancient caldera about 25 km (15.5 mi) in diameter, with a 100 m (328 ft) circumference. It is important to note that the volcano's crater and surrounding area are often closed off due to activity, so check its status before planning to visit. An aerial lift provides a bird's-eye view of the dramatic landscape, while a parking lot only a minute's walk away caters to the less-able-bodied. For travelers who use our international travel planner, Aso holidays become easier to arrange, with trips to the Mt. Aso and other attractions mapped out and timetabled.

  • Definitely worth a visit, but make sure to check the crater’s status since it’s constantly changing. If you have asthma or you suffer from any lung diseases, you shouldn’t get in The entrance fee was 800 yen for a car
  • Mount Aso is beautiful and the largest active volcano in Japan. It takes about an hour and half to drive up here from Kumamoto and when you make it to the top you can walk around and witness the unique topography created over time. Some parts are lush and green and others look like the surface of Mars. Make sure you check the sulfur readings before you begin your journey because if the conditions aren't favorable the peak will be closed to visitors. I was fortunate to make it to Mount Aso while visiting Kumamoto in July 2021.
