Aso, in Kumamoto-prefecture

 

Aso is located almost in the center of Kyushu and possesses the world’s largest

Caldera with 18km west-east and 24km north-south, created by 4 periods of explosive

volcanic activity in the ancient times, 3 million years ago.

Surrounding the caldera is the world’s largest outer mountain, and there are 5 mountains

included Mt. Naka which is still active volcano in the outer mountain, where the crater can

be viewed from the top. 

Daikanbo peak, on the outer edge of the Aso Caldera is a must place

to visit offering panoramic views of the magnificent scenery including the

five mountains of Aso and the serene and beautiful green plains.

 

The 4 times volcanic activities in the ancient time also affected the surrounding area

of Aso, resulting in the formation of the following nature.
