This Isn't a Starfish — It's a Rare Sand Found Only in Japan
By Bruce Wayne - Sep 3, 2024
Okinawa, Japan, is famous for its unique "star sand," composed of tiny, star-shaped grains. This rare phenomenon, found on specific beaches, is the result of ancient marine organisms that hold cultural significance for the Okinawan people.
Origins of Star Sand
Star sand is composed of the exoskeletons of microscopic marine organisms called foraminifera. These tiny creatures lived in the ocean millions of years ago, and their star-shaped remains have accumulated on Okinawan beaches over time.
The grains are particularly found on the islands of Taketomi and Iriomote, where they have become a natural wonder and a symbol of the region's rich marine biodiversity.
