This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.
|Nakano-sima | Nakano-shima|
|Feature Name||Feature Type||Elevation||Latitude||Longitude|
|Ontake||Stratovolcano||979 m||29° 51' 33" N||129° 51' 25" E|

|The 9-km-long island of Nakano-shima is seen in an aerial perspective from the SE in this computer-generated graphic image. On-take, the 980-m-high peak at the far end of the island, is the historically active volcano of Nakano-shima. The southern part of the island consists of an older dissected volcano primarily composed of pyroclastic rocks. Kuchino-shima (upper right) lies NE of Nakano-shima.

|Nakano-shima island is seen here from a beach on Kuchino-shima to the NNE. The active andesitic cone on On-take, with a summit crater that fills with water during the rainy season, forms the conical peak at the right. The 9 x 5 km island of Nakano-shima is surrounded by coral reefs. A flat plateau separates an older dissected volcano on the south from On-take. Only very minor activity has been reported in historical time.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

|Large Eruptions of Nakanoshima||Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).|
|WOVOdat||WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.|
|EarthChem||EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).|
