Discover Okinawa’s Underwater Paradise: Full-Day Snorkeling & Introductory Diving in the Kerama Islands

Seeing the Kerama Islands from Naha offers a perfect blend of adventure, natural beauty, and accessible marine wonderlands. For around $92.50 per person, you get a roughly eight-hour excursion that takes you into some of Japan’s most breathtaking coral reefs and vibrant marine environments. Led by passionate staff and friendly guides, this tour is designed to be safe, inclusive, and packed with opportunities to see sea turtles, tropical fish, and coral gardens.
What we really appreciate about this experience is how it manages to balance professionalism with a relaxed, fun atmosphere. The guides are well-trained, ensuring everyone feels comfortable — whether you’re a first-timer or more experienced.

The comfort of the boat and the opportunity to snorkel freely after your first dive makes this a flexible, value-packed way to enjoy Okinawa’s underwater scenery.
