Mount Naka-dake Crater
Mount Naka-dake was shaped more than 20,000 years ago and was active until just recently. Its magnificent views often lead to it being called The Grand Canyon in the East! After you depart from the Sensuikyo cable car, on the east side of the central crater, a 10-minute walk up a steep slope brings you to the eastern crater observatory where burning red magma and white rising steam can be seen. Access to the crater is sometimes restricted, due to the presence of toxic volcanic gas.
