Kikai Caldera (??????, Kikai karudera) is a massive mostly submerged caldera up to 19 kilometres (12 mi) in diameter in the Ōsumi Islands of Kagoshima prefecture, Japan. It is the remains of the ancient eruption of a gigantic volcano. Kikai Caldera was the source of the Akahoya eruption, one of the largest eruptions during the Holocene (10,000 years ago to present). About 6,300 years ago, pyroclastic flows from that eruption reached the coast of southern Kyūshū up to 100 km (62 mi) away, and ash fell as far as Hokkaidō. The eruption produced about 150 km³ of tephra,[2] giving it a Volcanic Explosivity Index of 7. Kikai is still an active volcano. Minor eruptions occur frequently on Mount Io (???, Iō-
