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]
