"Mt Usu" A smoking crater on the west side of Mt. Usu.

Mt. Usu is an active 737 meter tall volcano located south of Lake Toya.
 
After observation, it has been determined that this volcano displays eruption activity four times every 100 years, making it one of the more active volcanos in the world. If you get up close to this smoking crater, located on the west side of the mountain, you can truly feel the raw power of nature!
