"Grazing lands and volcanic activity" This gorgeous must-see geosite includes a rain fed pool and a 785,000-square-meter grassland growing inside an inactive crater in the foothills of Mt. Eboshi. It's a perfect place to stop for a stroll alongside the cows and horses that graze peacefully as Mt. Nakadake sends up smoke in the distance. Horse rides through the grasslands are another popular activity. The Aso Volcano Museum sits just adjacent to Kusasenri-ga-hama. With a large collection of materials related to the volcano, the museum is an excellent place to deepen your understanding of the region's history. Displays include large dioramas showing the process of Aso Volcano's formation as well as exhibits on volcanos around the world. The museum is also the only place to view real-time footage of Nakadake Crater taken with a recently-installed camera system.

"Nakadake Geosite" Sense the activity of the earth through and active volcano. After Aso Caldera was formed, a number of volcanos – most of them stratovolcanos – rose inside it, comprising the central cone group. In contrast to the desolate scenery immediately surrounding the crater, an enchanting landscape of meadows and plantation forests covers the volcano's slopes and foothills. Mt. Nakadake stands in the approximate center of the central cone group. One of the few volcanos in the world where observers can peer directly inside the crater, the mountain attracts a constant stream of tourists. The compound crater is aligned approximately north to south, measuring 900 m in that direction and 400 m east to west. Ancient documents and observations over the past 100 years reveal that volcanic activity shifts over time between seven craters arranged in a line. In the late 1800s the first crater was active, while from 1923 to 1930 the fourth was.
