Mt. Showashinzan

Mt. Showashinzan (昭和新山) in the south of Lake Toya is a volcanic lava dome with 398 m in height. Red surface of the mountain catches eyes, so it is conspicuous at a distance. Speaking of the Mt. Showashinzan, an episode that a wheat field rose just overnight is famous. Actually, the Mt. Showashinzan changed to a current shape after 2 years. It was named "Showashinzan" because Mt. Showashinzan rose in 1944 (Showa period) and it has designated as a special natural treasure since 1957. This volcano is called a type of the beronite volcano, and it is one of only 2 volcanos in the world. Mr. Masao Mimatsu (三松 正夫) that is famous for observing the Mt. Showashinzan and making Mimatsu Diagram (ミマツダイヤグラム) bought the land, so the Mt. Showashinzan is a private land at present. By the way, Mt Usu is very close from the Mt. Showashinzan. Admission free.
