What to Expect from the Tour

This experience is designed to showcase Okinawa’s best underwater spots, focusing on three carefully selected diving sites around Tokashiki Island, Zamami Island, and Aka Island. Unlike larger group excursions, this tour emphasizes personal attention, with guides adjusting the itinerary based on weather, sea conditions, and your experience level.

Morning: Transportation and Introduction

The day begins with pick-up directly from your Naha hotel, which is a major plus for ease and comfort. The transport is described as friendly and smooth, with reviews praising the punctuality and professionalism of the staff. Once at the port, you’ll board one of their own boats—an advantage that allows for flexible, tailored guiding.

First Dive and Marine Exploration

Guided by experienced instructors like Koyama or Cristina, you’ll get a thorough briefing tailored to your skill level. The guides are praised for their patience and knowledge, making even nervous divers feel at ease. Expect to see colorful coral reefs, small and big fish, and possibly sea turtles or sharks, depending on the site.

Reviewers mention that the marine life is abundant and the underwater views are breathtaking. As one diver noted, “The view under the sea was stunning, and I discovered many sea animals,” highlighting the richness of the environment. The guides also respond well to questions about specific marine creatures, which enhances the experience for curious explorers.

Lunch and Midday Break

Lunch is included—hot Okinawa soba and oden—offering a comforting break during the busy day. Reviewers have appreciated the quality and warmth of the meal, especially on colder days, as seawater temperature remains quite comfortable (never below 22°C). The boat is equipped with a cabin heater and engine heater, ensuring everyone stays cozy even when the weather isn’t ideal.

After lunch, you’ll head to additional sites. The guides carefully select locations to maximize marine diversity and visual appeal.

Snorkeling and Extra Activities

For non-divers or those waiting their turn, snorkeling is available, sometimes combined with guided tours. The boat rental offers free swim rings, making floating fun easier, and rental cameras are on hand if you’d like to capture your marine encounters (for an extra fee).

Whale Watching Season

From January 12th to March 31st, whale watching is included, with a high probability of spotting humpback whales on the return trip. One reviewer shared that they lucky enough to see whales on the way back, making the journey even more memorable.

Extra Perks and Seasonal Touches

The Intangibles: Guides, Comfort, and Atmosphere

Guides like Cristina and Takashi receive praise for their knowledge, patience, and friendliness. Several reviews mention how they accommodate beginners and experienced divers alike, adjusting the tour to fit individual needs. The small group sizes and own boats mean you get more personalized attention, which is a distinct advantage compared to larger tour operators.

The boats themselves are described as clean and well-equipped, with cabin heaters and engine warmth that contribute to a comfortable environment during winter months. Reviewers also appreciate the hot water showers and changing rooms available after dives, which make changing and warming up hassle-free.

Price and Value

At $135 per person, this tour offers a lot for the cost. Included are full rental equipment, tanks, weights, towels, tea, and even transportation, which makes it quite convenient. The addition of whale watching from January to March adds seasonal value, and extra optional activities like GoPro rentals or special events can enhance your day without breaking the bank.

Comparing the cost against the reviews, many find the quality of guides, the marine diversity, and the organization justify the price. The hot meals and seasonal perks like shaved ice are thoughtful touches that boost overall value.

Considerations Before Booking

Ensure you hold a current diving certification (C-card); this tour is not suitable for snorkelers without diving licenses. The boat can get crowded with mixed groups of snorkelers, introductory, and experienced divers, which might affect your comfort if you prefer a more private experience.

Weather can influence the day’s plans—severe sea conditions might lead to cancellations or schedule changes. If you’re prone to seasickness, consider taking precautions beforehand, as the boat trip can last several hours. Also, early reservation is recommended, especially during peak season, to secure your spot and preferred pickup.
