Located roughly 70 kilometers northwest of Fukuoka, Okinoshima Island is a hidden gem recognized as a UNESCO World Heritage Site since 2017. Reached only by a two-hour boat ride, divers are greeted by impressive schools of ascidians and migrating fish like the Hiramasa. The vibrant landscape teeming with colorful red and yellow snappers among the soft corals is a must-see for underwater enthusiasts.
