nihongo|Showashinzan|昭和新山|Showa-shinzan is a volcanic lava dome in the Shikotsu-Toya National Park, Hokkaidō, Japan, next to Mount Usu. The mountain was created between 1944 and 1945. Initially, a series of strong earthquakes shook the area, and wheat fields were rapidly uplifted. Lava broke through the surface and the current peak was created. The peak is now Convert|398|m|ft|0|abbr=on tall, and still actively smoking.

The name "Showashinzan" literally means "Showa new mountain", as it formed during the reign of Emperor Hirohito, known as the Showa period. When Showashinzan first appeared, the Japanese authorities were worried that it might be interpreted as an unlucky wartime omen, and its existence was kept secret. Much of the information about peak's formation during these years comes from local postmaster Masao Mimatsu, who kept detailed measurements of its progress.
