Nagura Coral Garden is a boat-access coral garden in Nagura Bay off Ishigaki Island, built around dense reef growth, table corals, and sandy patches with clear water over a shallow-to-moderate profile. It is a relaxed, photogenic site where calm current and coral density matter more than depth, and it works well for mixed-level diving and easy snorkeling.
