From Wikipedia

Kaimondake , or Mount Kaimon, is an undissected volcano – consisting of a basal stratovolcano and a small complex central lava dome – which rises to a height of 924 metres above sea level near the city of Ibusuki in southern Kyūshū, Japan. The last eruption occurred in the year 885 CE. Because of its conic shape, Mt. Kaimon is sometimes referred to as "the Fuji of Satsuma". It is one of the 100 Famous Japanese Mountains.
