Manta Scramble - Japan Diving
Site Overview
Manta Scramble is Ishigaki's most famous dive site renowned worldwide for reliable reef manta ray encounters throughout the year with peak activity from May through November. The site features a prominent coral-covered pinnacle rising from twenty-five metres to five metres with a natural manta cleaning station at ten to fifteen metres where reef mantas visit regularly to have parasites removed by cleaner wrasse. The pinnacle is surrounded by deep blue water creating an open ocean environment where multiple manta rays often circle simultaneously providing spectacular observation opportunities. Mantas with wingspans reaching three to four metres glide gracefully around the cleaning station in the crystal clear Ishigaki waters creating unforgettable underwater encounters. The coral reef surrounding the pinnacle supports exceptional biodiversity with hundreds of tropical fish species schooling jacks and occasional eagle rays adding to the pelagic excitement. Strict observation protocols are enforced with divers maintaining passive positions on the reef to avoid disturbing the mantas during their cleaning visits. The combination of reliable manta encounters exceptional water clarity and vibrant coral reef makes Manta Scramble one of Japan's most iconic dive destinations drawing divers from around the world.
