Living coral reefs serve as natural breakwaters to protect the island’s coastal areas while providing valuable habitats for marine life. Ryukyu limestone — the soft, porous limestone formed by petrified coral reefs — has long been used as a building material for stairs, pavement, and stone walls. Fossilized coral has also been used as a protective good-luck charm in Okinawa through the ages.
