Otake (御岳, O-take) is a stratovolcano[1] in the Tokara Islands of Japan. It is the largest mountain on Nakanoshima, which is part of Toshima in Kagoshima District of Kagoshima Prefecture. Being the largest mountain on a small island, it is also referred to as Nakanoshima.
The mountain is an andesitic volcano. The volcano had a minor mud eruption in January 1914. In October 1949 the summit crater produced an ash cloud.[1][2] The rock of the mountain is non-alkali mafic rock produced in the last 18,000 years.[3]
Sulphur mining took place on the southeast flank until 1944. During the rainy season, the summit crater fills with water.[2]
