The Itinerary Breakdown: What Makes This Tour Tick

This tour is designed for certified divers looking to spend a full day exploring Okinawa’s stunning marine environment. Departing from Naha, you’ll board a high-speed boat — an exciting start that immediately builds anticipation. The boat ride itself is part of the fun, offering sweeping views of neighboring islands like Tokashiki, Zamami, and Aka, all while feeling the cool sea breeze.
Once at the diving spots, you’ll visit 2-3 carefully selected sites, each offering unique underwater features.

Many reviews highlight the professionalism of guides like Cristina and Takashi, who are praised for their patience, especially when answering questions about marine life and terrain.
For those who haven’t been diving in a while, or if you’re a beginner, the guides are attentive and willing to tailor the experience. They focus on making sure everyone feels comfortable — even those who are there solo or in a small group. You’ll get full rental gear, including tanks, weights, and even a rental camera if you wish to document your underwater adventures.

One diver noted seeing a turtle and a small shark, emphasizing how diverse and lively these sites can be. The guides’ careful selection of diving locations ensures minimal disturbance to marine flora and fauna, making each dive both enjoyable and environmentally responsible.

Weather & Seasonal Considerations

While Okinawa enjoys mild winter temperatures, the water stays comfortably warm — never dropping below 22°C, making snorkeling and diving pleasant even in cooler months. The guides go to great lengths to keep participants warm with bo Coat rentals, cabin heaters, and engine heaters. Still, weather may lead to last-minute plan changes, so flexibility is key.
The Value of This Tour

Priced at $135 per person, this tour packs in quite a lot: multiple dives, whale watching, gear rental, and transportation. Compared to the cost of booking separate activities, this package offers convenience and good value, especially considering the personal guidance from experienced instructors. Several reviews emphasize the professionalism and friendliness of the staff, which greatly enhances the overall experience.
Authentic Local Touches & Special Events

An extra highlight is the annual mochi pounding event on January 1st, a charming Okinawan tradition that adds cultural flavor to the trip. Plus, special occasions like birthday dives can be arranged, making the day not just about underwater exploration but also memorable personal moments.
Final Thoughts: Who Will Love This Experience?

This tour offers a well-rounded day of diving, whale watching, and island scenery, making it ideal for certified divers who want to maximize their Okinawa visit. If you appreciate professional guides, authentic underwater sites, and convenient logistics, you’ll find great value here. It’s especially suited for travelers comfortable on boats and eager to see marine wildlife, both below and above the water.
However, if you’re not certified or prefer a more relaxed, land-based experience, this tour isn’t suitable. Weather can impact whale sightings, so don’t rely solely on that aspect. And for those with mobility issues or health concerns, the physically active nature might be challenging.
This is a fantastic option for experienced divers wanting to explore the Kerama Islands with knowledgeable guides, in a safe and friendly environment. You’ll leave with vivid memories of Okinawa’s vibrant waters and possibly some whale sightings to top it off.
