Okinawa: Naha – 1 Day Kerama Islands Diving Experience (License Required)
If you’re looking for a full day of underwater adventure around Okinawa’s famed Kerama Islands, this tour offers a lot to love. For $135 per person, you get to explore 2-3 authentic diving spots, enjoy whale watching from January through March, and even participate in a traditional mochi pounding event on New Year’s Day if you’re lucky enough to be there at the start of the year. The tour departs from Naha and uses its own boats, making it a personalized and flexible experience.
What we really appreciate about this tour is how it balances professional guidance with authentic local traditions. The guides are experienced and attentive, ensuring even those who haven’t been diving for a while feel secure and engaged. Plus, the chance to see whales in their natural habitat during winter adds a rare thrill you won’t find on every snorkeling or diving trip.
One potential consideration: this experience is only suitable if you already hold a certified diving license (C-card). It’s not intended for beginners or those without certification. Also, the tour’s schedule and activities depend heavily on weather conditions, so flexibility is key. This is a solid choice for certified divers looking for a comprehensive day in the sea that combines adventure, cultural fun, and wildlife sightings.
It’s best suited for adventurous, certified divers eager to explore Okinawa’s vibrant undersea world, enjoy some cultural activities, and maybe even witness whales. Solo travelers, groups, or couples who appreciate well-guided tours with attention to safety will find this experience particularly worthwhile.

The Itinerary: How the Day Unfolds
The day kicks off with a morning departure from Naha’s port, where the crew ensures everyone is comfortable with the gear and plans for the day. The first highlight is the cruise across the Kerama Islands—areas renowned for their vibrant coral reefs and abundant marine life. You’ll visit 2-3 carefully selected diving points, chosen daily by the guides based on current conditions and the best visibility.
One of the most appealing features is the personalized guidance. The guides are experienced and eager to answer questions about the terrain, fish species, or anything else you’re curious about. They’re particularly attentive to beginners or rusty divers, making sure everyone can enjoy the experience safely and comfortably.
Underwater Highlights
While above water, the boat offers stunning views of surrounding islands and turquoise waters. Underwater, you’ll find colorful reefs, schools of fish, and possibly some larger visitors like sea turtles or small sharks. The guides emphasize teaching a fun, relaxed diving style that caters to your experience level, ensuring you’re comfortable both in and out of the water.
From reviews, we know that marine life sightings are common, with divers seeing everything from small fish, octopuses, and sea snakes to turtles, sharks, and even whales during winter. As Jessica noted, “We saw small shark and sea snake, of course many different kinds of fish,” which hints at the diversity of the reefs.
Cultural & Seasonal Events
A unique aspect is the January 1st mochi pounding event, a traditional Japanese celebration that adds a cultural touch to your day. If you book on New Year’s Day, you’ll enjoy this all-you-can-eat event along with the diving. During August and September, the tour offers a shaved ice service, perfect for cooling down after a dive.
From January 12th to March 31st, whale watching becomes available. Guides will do their best to locate whales, but as with all wildlife sightings, there’s no guarantee—a point echoed in reviews, which mention that weather and sea conditions can influence visibility.

The boat can get crowded—up to 50 people, according to some reviews—so patience and clear communication are important.
Wildlife & Marine Life
Most divers come away excited about the marine biodiversity. The reefs are alive with fish, octopuses, turtles, and sometimes sharks. The chance to see whales from January to March adds a rare bonus, though the sighting is weather-dependent. You’ll also have the opportunity to rent a camera or Gopro if you want to document your underwater moments.
Authentic Experiences & Practical Tips

Beyond the diving, the tour offers a glimpse into local Okinawan culture with the mochi-pounding event and the chance to enjoy hot Okinawa soba and oden for lunch—warming dishes perfect after a chilly morning in the sea.
A major plus is the transportation logistics—pick-up from your hotel in Naha is included, saving you time and hassle. Parking is available at the port for those driving, with a small fee. The guides respond well to special requests, whether it’s a birthday celebration or specific dive spots.
Considerations for Travelers
Because the tour is weather-dependent, there’s a chance that whale sightings or some diving plans may be delayed or altered. It’s wise to stay flexible and keep an eye on the weather forecast. Also, since it’s geared toward certified divers, non-certified or beginner snorkelers will need to look elsewhere or opt for beginner-friendly tours.
If you’re wary of seasickness, taking medication beforehand is recommended. The guides are very professional, but delays caused by rough seas or weather can happen. Lastly, early booking is advised, especially in high season, to secure your spot and any special requests.
Who Should Consider This Tour?

This experience is ideal for certified divers who want to explore Okinawa’s underwater world with knowledgeable guides. It’s especially appealing if you enjoy wildlife sightings, like whales or turtles, or want to combine marine adventure with local traditions. Solo travelers and small groups who value personalized guidance and well-organized logistics will find this tour a great fit.
It’s less suitable for families with young children or non-divers—unless they’re comfortable snorkeling and don’t mind the certification requirement. Also, if you’re seeking a relaxing, passive day without much physical activity, this might be more adventurous than you’re after.
