Okinoerabujima , also known as Okinoerabu, is one of the Satsunan Islands, classed with the Amami archipelago between Kyūshū and Okinawa.

The Amami Islands is an archipelago in the Satsunan Islands, which is part of the Ryukyu Islands, and is southwest of Kyushu. Administratively, the group belongs to Kagoshima Prefecture, Japan. The Geospatial Information Authority of Japan and the Japan Coast Guard agreed on February 15, 2010, to use the name of Amami-guntō (奄美群島) for the Amami Islands. Prior to that, Amami-shotō (奄美諸島) was also used. The name of Amami is probably cognate with Amamikyu (阿摩美久), the goddess of creation in the Ryukyuan creation myth.
