Mount Usu (Sobetsu Town, Hokkaido).

Overview (history, characteristics, attractions)

Mount Usu is an active volcano located in Sobetsu Town, Usu District, Hokkaido, and is part of Shikotsu-Toya National Park, which includes Lake Toya. The mountain is located on the rim of a caldera, and is notable for having erupted repeatedly throughout the Showa and Heisei periods. In particular, the formation of Showa-Shinzan from 1943 to 1945 (Showa-Shinzan is a lava dome created by the eruption of Mount Usu), as well as the eruptions in 1977 and 2000, had a major impact on the local topography and people's lives.

As a result, the landscape of the majestic crater, lava cones, hot spring town, lake and volcano has become a tourist attraction, and the area is highly regarded geologically as a geopark (Lake Toya-Usuzan Geopark).A major attraction is the close-up view of the crater and Showa-Shinzan from the ropeway and observation deck.

Highlights

• Usuzan Ropeway: A short climb from the base of the mountain to near the summit. From the observation deck near the ropeway's mountaintop station, you can enjoy a spectacular view of Mount Showa-Shinzan, Lake Toya, and the crater cluster.
• Showa Shinzan: A lava dome formed in a short period of time during the 1943 eruption. It has been preserved and can be seen up close from the observation trails and observation points.
• Usu Volcano Memorial Museum (or Geopark Facility): This is a great place to start your visit as it houses exhibits that teach you about the history of eruptions, the workings of volcanoes, past damage and the recovery process.
• View of the crater and crater floor: There are several crater remains scattered around the summit, and there is a trail to observe the traces of volcanic activity (there are some restricted areas).
• View of Lake Toya: The view of Lake Toya from Mount Usu is particularly beautiful, and its appearance changes depending on the season and weather. It is especially spectacular when combined with the autumn leaves.
