In the past, Sakurajima used to be its own island volcano. However, after countless eruptions, the lava flows spread far enough to connect it to the Osumi Peninsula in Japan. The volcano has erupted every year since 1955, which has created an issue for the nearby city of Kagoshima.
Currently, it is the most active volcano in Japan with an eruption in 2009 killing thousands. One of the most notable eruptions occurred in 1914 after being dormant for over a century, with the lava flows swallowing the surrounding islands.
