On Thursday, October 12, 2023, coral planting activities were conducted within the Busena Underwater Observatory. This initiative, aimed at preserving the valuable ecosystem of Okinawa's coral reefs and revitalizing fisheries and tourism resources, has been ongoing since three years ago with the support of Okinawa Coral Reef Conservation Council.　It's part of a joint effort with the Okinawa Convention & Visitors Bureau to introduce planting techniques tailored to coral planting sites, as well as to develop new techniques. The goal is to contribute to the regeneration of the precious coral reef ecosystem and fisheries and tourism resources.

On the day of planting, we used a tetrapod-type attachment device to suit the underwater rocks in Busena Marine Park. As it is inevitable that seawater temperatures will continue to rise due to global warming, we planted cultivated strains of the leaf coral (Pavona decussata), which is resistant to high water temperatures, instead of the Acropora species that are commonly used today.
