Aso (Aso region, Kumamoto Pref.)

The central cone group of Aso consists of five peaks located in the mountain's ancient caldera1, and one of these peaks, Mt. Naka, has a steaming, active volcano crater. This site is well known worldwide, because the west side of the peak is accessible by road, and it is unique as the only place in the world where you can look down into the mouth of a volcano.

In addition, there are a variety of eco-trekking courses available that take good advantage of the natural resources in the area.

Note:

A caldera is a volcanic feature formed by the collapse of land following a volcanic eruption, forming a cauldron-like region. Although they are related, they are not the same as volcanic craters.

There is an "Onsen Pass" available that will let you enter three hot springs of your choice, such the popular "Kurokawa Onsen," "Uchinomaki Onsen," famous for the number of great writers who have visited there, and the "Jigoku - Tarutama Onsens," which are the facilities closest to the volcano, Mt. Aso.

Centered around the Aso Shinto Shrine, steeped in history and dedicated to the ancient gods of Aso, agricultural festivals are held in Aso in all of the four seasons, including the "Gotae Matsuri" (rice-planting festival) in summer, and the "Hiburi Jinji" (Shinto torch ritual, etc.
