From Naha: Scuba Diving Trip in Kerama (for Certified Divers)

Imagine waking up early in Naha, boarding a boat with a friendly guide, and heading out to explore some of the most vibrant underwater scenery you’ll find in Japan. For around $211 per person, this full-day trip from Okinawa’s main city offers a chance for certified divers to experience two guided dives in the protected waters of Kerama National Park. The trip lasts about 8 hours, and what we love about this tour is its emphasis on small-group comfort and professional instruction, making it suitable for divers who crave an authentic, well-organized adventure.
We particularly appreciate the small-group size (limited to just 4 participants), which ensures plenty of personal attention from the guides and a more relaxed atmosphere. The fact that equipment rental and insurance are included simplifies planning and adds value, while the free underwater photos give you a wonderful way to remember the day.
One potential consideration is the weather dependency—if the seas turn rough or the weather turns bad, the boat ride might be canceled or rerouted. It’s worth being flexible on your schedule and understanding that this is an outdoor activity at the mercy of nature.
This tour is perfect for experienced divers staying in Naha who want a seamless, hassle-free day of exploring the underwater world while enjoying expert guidance. It’s also ideal for those who appreciate small-group settings and personalized service over large, crowded tours.
