Mount Asama, on the border between Gunma and Nagano, is one of the most active volcanoes in Japan. Onioshidashi Volcano Park is characterized by volcanic sediments that were deposited here during the great eruption of the mountain in 1783. The great diversity of alpine wildlife in front of the volcanic landscape offers some truly spectacular sights, black rocks formed by hardened lava criss-crossing the landscape.
