Viewing the Aso Volcano Crater

This magnificent caldera extends 24 km north-south and 18 km east-west, and craggy volcanic rock faces cover an area of 4 km around it. Aso Gogaku, the Five Peaks of Aso (Mt. Nekodake, Mt. Takadake, Mt. Nakadake, Mt. Eboshi and Mt. Kishima), soar upwards from the central part of the caldera; currently, Mt. Nakadake is continuously active, emitting white smoke. This caldera, located on Mt. Nakadake, is one of the largest in the world. This huge volcanic crater has a diameter of 600 meters, depth of 130 meters, and circumference of 4 km, and visitors can enjoy dynamic scenery and the “living” Mt. Aso here. When the volcano becomes particularly active, visitors cannot go near the crater.
