Mount Usu (有珠山, Usu-zan[3]) is an active stratovolcano in the Shikotsu-Tōya National Park, Hokkaido, Japan . It has erupted four times since 1900: in 1910 (which created Meiji-shinzan[4]), 1944–45 (which created Shōwa-shinzan), August 7, 1977,[5] and on March 31, 2000. To the north lies Lake Tōya. Mount Usu formed on the southern rim of the caldera containing the lake.

Mount Usu and Shōwa-shinzan are major tourist attractions in the Shikotsu-Tōya National Park. A rope-way on Mount Usu takes visitors to viewing platforms overlooking Shōwa-shinzan. The 1977 eruption is mentioned in passing in Alan Booth's travelogue, The Roads to Sata. The 2008 G8 Summit was held near Mount Usu at Lake Tōya.[6]
