The Kerama Islands are a subtropical island group 32 kilometres (20 mi) southwest of Okinawa Island in Japan.

The Okinawan language or Central Okinawan is a Northern Ryukyuan language spoken primarily in the southern half of the island of Okinawa, as well as in the surrounding islands of Kerama, Kumejima, Tonaki, Aguni and a number of smaller peripheral islands. Central Okinawan distinguishes itself from the speech of Northern Okinawa, which is classified independently as the Kunigami language. Both languages are listed by UNESCO as endangered.
