Mt. Aso is the largest volcano in the world in terms of its outer rim. It is also active. It`s huge, unbelievably huge. You`ll have to see it for yourself.
There`s a visitors center nearby where you can get a look inside of the inner rim which has regular eruptions, and what looks like boiling mud coming to the surface.

The Chikugo River, rises under the Mt.Aso, is 143 km long and is the longest river of Kyushu.
This river flows through Kumamoto-ken, Oita-ken, Fukuoka-ken and Saga-ken and it enters to the Ariahe Bay.
It is very important to local agriculture as it is used to irrigate some 40,000 hectares of rice field on the Tsukushi Plain.
A walk by this river shows us many different faces during the year. In April you can find dandelions, horsetails and so on by the banks of the river.
On August 5 every year, near Kurume city, a famous fireworks festival is held. In the autumn, you will find beautiful cosmos flowers blooming.

Mt. Kuju is Kyushu's highest mountain. It still has a number of volcanic vents nearby and likewise there are a number of authentic onsens to experience.
Climbing Mt. Kuju takes several hours. I think the YMCA group that I was with and I got to the summit after about 4 hours. The interesting thing was the large number of hikers climbing the mountain at the same time. I was most amazed by the stamina of the children. They had very positive attitudes about this and didn't spend their time complaining.
After getting to the top, it was well worth it. We could see a number of small villages in surrounding areas. Also from the mountain top we could see plums of steam mixed with sulfur escaping from vents not so far away.
It was a great experience that I would love to do again.
One down side was the public restrooms, they are the pits. I recommend that you bring toiletries.
