The Keramas include the islands of Tokashiki, Zamami, Aka, and Geruma and a number of smaller uninhabited islands. The governing structure divide them among Tokashiki Village http://vill.tokashiki.okinawa.jp and Zamami Village http://vill.zamami.okinawa.jp, which also includes Aka and Geruma islands.
The small island villages preserve the flavor of Okinawan village life and the beaches are better than those on the main island. The ferries to these islands is less than $30 round trip and is probably one of the gread bargains of Okinawa travel. Humpback whales are visible during the January to April.
