Kuroshima (黒島; Yaeyama: Ffusïma, Okinawan: Kurushima), also known as "Kuro Island", is an island in Taketomi Town, Okinawa, Japan, part of the Yaeyama archipelago. The island has the approximate shape of a heart symbol when viewed from the air, and is marketed as "Heart Island". The name means "Black Island".
The island has an area of about 10 km2 (4 sq mi) and a population of approximately 210 as of 2006[update]. Kuroshima is a comparatively flat island, as the highest point is just 15 metres (49 ft) above sea level.
Cattle raising is a major economic activity and a yearly "cow festival" is held. Sometimes the island is marketed as "Island of Cows" as well, as there are more cows than inhabitants living on it. Tourist activities include diving and sunbathing.
