Nakano-shima volcano is a stratovolcano forming the 9 x 5 km island of the same name, which belongs to the Ryukyu Island chain in southern Japan.
Typical eruption style
The island is surrounded by coral reefs, but unlike older extinct ocean islands that sink and form reefs Nakano-shima's volcano is active. There are no known magmatic eruptions in historic times, but a small mud eruption occurred in 1914, and increased "smoking" was seen in 1949.
: 1949 (uncertain), 1914 (phreatic explosions)

An older, eroded volcano forms the southern half of the island and a flat plateau separates it from the present-day active volcano which forms the northern half and has an andesitic cone called On-take.
On-take contains a summit crater that is filled with water during the rainy season. Sulfur deposits were mined at a SE-flank solfatara until 1944.
