Shōwa-shinzan, Active lava dome in Sobetsu, Japan
The volcano reaches 398 meters in height and constantly releases sulphurous fumes from its summit, marking its continued geological activity in Hokkaido.
The formation emerged between December 1943 and September 1945, rising from wheat fields following intense seismic activity during World War II.
Local postmaster Masao Mimatsu created detailed scientific records of the mountain's daily growth through careful measurements and drawings from his window.
The Mount Usu cable car provides direct views of the volcanic formation, allowing visitors to observe the geological features from multiple angles.
The Japanese government restricted information about the volcano's emergence during World War II, considering its formation an unfavorable sign.
