Inside the Shikotsu-Toya National Park, in the island of Hokkaidō, not far from the active stratovolcano, Mount Usu, there is a 400-meter tall volcanic peak called Shōwa-shinzan. Shōwa-shinzan is Japan’s youngest mountain. It appeared on 28 December 1943 out of a wheat field accompanied by strong tremors and hot lava. As the molten magma broke through the surface, it uplifted the field and over the following two years the lava dome continued to rise until it reached a height of 398 meters.
