What It Feels Like
Okinawa combines easy shore dives, clear national park reefs, and serious blue water adventures. On the main island you can drop into soft coral gardens at Sunabe Seawall, explore the Blue Cave and Cape Maeda, or run north to Sesoko and Motobu. Daily boats from Naha, Chatan, and Onna run to Kerama National Park for multi dive trips over coral walls, bommies, and sea turtle cleaning stations. With a bit more time you can connect via Naha to Ishigaki for mantas, Miyako for caverns, or Yonaguni for winter hammerheads and the underwater Monument, all while staying inside Japan's reliable safety and transport systems.
Signature Sites
Start Here
A classic Chatan shore site with steps straight into the water, Sunabe Seawall is nicknamed the underwater flower garden for its dense soft corals, anemones, and macro life, all between about {{ 5 | distance:m }} and {{ 20 | distance:m }}.
A Kerama Islands favorite with coral ridges stepping down to around {{ 25 | distance:m }}, frequent turtles, and usually gentle current, making it a relaxed national park showcase for Open Water divers.
Advanced
Okinawa's iconic cavern at Cape Maeda glows an electric blue when sunlight reflects off the sandy bottom into the chamber.
Just beyond the Blue Cave entrance, Cape Maeda drops from shallow reef into walls covered in soft coral and sponges, with frequent schooling fish and occasional pelagics on outgoing tide.
An advanced Kerama site where ridges, channels, and drop offs funnel current and schooling fish.

Operator Checklist
- Most Kerama and Blue Cave trips require advance booking, especially on weekends, national holidays, and during Japanese school holidays. Boats from Naha often meet around {{ 7 | distance:hour }} or {{ 7.5 | distance:hour }} in the morning and return mid afternoon, so plan your arrival day as non diving. Many shops in Naha, Chatan, and Onna offer full rental gear and guiding in English or other languages. Check whether prices include Kerama environmental levies and port fees. Keep at least 18 to 24 hours between your last dive and any flights, especially if you are doing repetitive deep or decompression limited profiles to Yonaguni or similar sites.
