Camel Mountain (Rakuda-yama) Geosite

Scenery featuring intrusive rocks

Rakudayama, or Camel Mountain, features a prominent dyke, which in geological parlance refer to a rock that forms in a crack in an older rock. This geosite is an excellent place to understand how that process works. Because the rock is easily approachable, visitors can examine the surface of the dyke as well as its cross-section, a columnar joint, in detail. Minamiaso Visitor Center and adjoining Aso Wildflower Garden, whose collection focuses on Aso's plant life, are located nearby.

Camel Mountain (Rakuda-yama)

This exposed section of an intrusive dyke measuring 5 m thick and several dozen meters from east to west cuts into the southeastern section of Aso's caldera wall, which is made of pyroclastic basalt pre-dating Aso Volcano. The name Rakudayama means Camel Mountain and originates in the fact that the dyke resembles a camel's back when viewed from its north or south side.

Aso Folk School

Aso Folk School

Located in a former elementary school built in 1951, Aso Folk School offers a place to learn about the lifeways and culture of previous generations. When the Kamishikimi Elementary School shut down in 2003, a group of graduates and local artisans and writers came together to preserve the traditional wood structure, creating this innovative center.
