Miyazaki Coast Drift - Japan Diving
Site Overview
Miyazaki Coast Drift is an exhilarating drift dive along the southeastern coast of Kyushu where the warm Kuroshio Current sweeps nutrient-rich water past coral-covered reef slopes creating exceptional marine biodiversity and thrilling current-swept diving conditions. The reef extends from eight to twenty-eight metres depth with current-facing surfaces covered in dense gorgonian fans soft corals and filter-feeding organisms that thrive in the nutrient-rich flow. Scalloped hammerhead sharks are seasonally observed patrolling the current while eagle rays and schooling jacks are drawn to the nutrient-rich water column. The drift diving format allows divers to cover a large area of reef during a single dive observing diverse marine communities and topographical features as the current carries them along the coast. The Kuroshio Current brings subtropical species northward creating a unique mix of temperate and tropical marine life on the Miyazaki reefs. The site is best dived on incoming tides when the current is most manageable and visibility is at its peak. The combination of thrilling drift diving Kuroshio biodiversity seasonal pelagic encounters and temperate reef exploration makes Miyazaki Coast Drift one of Kyushu's most exciting advanced dive destinations.
