Aso Nakadake Crater

Overview

Aso Nakadake Crater is an iconic symbol of Mount Aso. Formed by a massive eruption approximately 90,000 years ago, the Aso Caldera is one of the largest in the world, stretching 18km east-west and 25km north-south. Nakadake, one of the Aso Five Mountains, sits in the center of this caldera. This still-active crater, with its impressive 4-kilometer circumference, constantly emits plumes of white smoke. At the bottom of the crater is a crater lake, or hot spring, containing sulfur and other mineral-rich waters. Volcanic gases also vent from areas around the crater, allowing you to feel the heat firsthand. Aso Nakadake Crater is a dynamic location where you can truly experience the power of the Earth.
