Nabana no Sato
Amami Oshima's coastline features a host of beautiful, uncrowded beaches that provide great opportunities for sunbathing and snorkeling. Many beaches provide little beyond a parking lot and public restrooms if indeed they have any facilities at all. The best time to go swimming is between May and October, when air and water temperatures are suitable for beach activities. When entering the water, beware of strong currents that can pull you out to sea and poisonous creatures.
Additional, even more secluded beaches are found along the coast of Kakeromajima Island, a short ferry ride south of Amami Oshima.
Facilities: small car park, restrooms
Generally considered the best beach on the island, this idyllic beach is located just a ten minute drive north of the airport.
