Which volcano is the most active in Japan?

Sakurajima sits in Kagoshima Bay on Kyushu and is one of Japan’s best-known active volcanoes. It was once an island, but a 1914 eruption connected it to the mainland with lava flows. Since then, it has produced many explosive eruptions and ash plumes, making it one of the country’s most closely monitored volcanoes. The volcano’s proximity to Kagoshima city means even moderate eruptions can affect daily life. Sakurajima is a textbook example of a dangerous, active volcano near a populated area.
