Star Sand Shores of Hoshizuna — Iriomote’s Hidden Wonder
Nestled along the remote coastline of Iriomote Island, Hoshizuna Beach is one of Okinawa’s most fascinating natural treasures. Its shoreline is famed for tiny star-shaped grains of sand that sparkle beneath the tropical sun.
This rare coastal phenomenon, combined with crystal-clear waters and lush island surroundings, creates a secluded paradise rich in both beauty and scientific wonder.
The Mystery of Star Sand
The “star sand” is not traditional sand but the fossilized shells of microscopic marine organisms known as foraminifera.
Over time, ocean currents carry these delicate star-shaped remains to the shore, forming the beach’s unique texture.
