Mt.Aso, Kumamoto Prefecture

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, Minamiaso-mura holidays become easier to arrange, with trips to the Mt.Aso and other attractions mapped out and timetabled.

    Seems to point to the large crater or Caldera, in a broad sense includes Mt. ASO in the narrow sense is a central part of ASO wushan area. When you looked at the crater floor from the Grand view peak Observatory of Somma, was overwhelmed by the scale of. Because of the crater floor is not even half of the total area, has 380 km 2 area has 3 municipalities, 50000 people are living. A panoramic view of the world is worth a look.

    Caldera far mountains are so beautiful. Smoke was rising and was somehow sulfur. Also I think maybe.

    Did not go to the Summit because of bad weather, the volcano Museum, "learned". With the world's leading large Caldera Volcano in at 90000 years ago erupted pyroclastic cover Kyushu Central, this time ash is likely remain in formations in Hokkaido, Japan. On the way back I realized the size of the caldera at the Somma. No wonder country fire in Kumamoto.
