Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Oct 2026): ja.wikipedia, showcaves.com, the dive centres' websites (BIGHOLIDAY, Sun Island, Aquatic Adventure), visitokinawajapan.com, nap-camp, skyticket, the prefectural Miyako hospital, Ryukyu Shimpo and DAN. Toriike pin from Wikipedia; the boat sites have none. These are guided boat dives into caverns, halls and arches; the requirements come from the dive centres. Certification and configurations are estimates.
