The Japanese archipelago has volcanoes here and there. Occasionally, eruptive activity becomes active, affecting the local area.

However, it is rare for a mountain to be created rapidly.

In about 600 days from 1943 to 1945, the wheat field near Lake Toya in Hokkaido suddenly rose and became a mountain. This is called Showa Shinzan. The altitude of the summit is 407m.

It is a place where you can feel the energy of the earth. I think it is worth a look.
