Fukashima Island is a small Oita island with shallow coral reef water, colorful tropical fish, and a relaxed remote-island feel. It suits easy snorkeling and beginner-friendly reef diving, with the regular ferry schedule, limited island services, and the island's shallow reef layout shaping the day more than any technical underwater challenge.
