This tour emphasizes 3 top-quality diving locations around the famous Kerama Islands. The guide, who owns two boats, personally curates the best spots of the day based on weather and sea conditions. Expect this to mean a flexible, thoughtful approach that aims to showcase the most vibrant marine environments.

The sites are mainly around Tokashiki Island, Zamami Island, and Aka Island, each offering distinct underwater features like coral reefs, schools of colorful fish, and possibly larger marine animals. Reviewers mention the guides’ attentiveness to different experience levels, making this accessible even for those who haven’t been diving recently.

The Diving Experience

Starting early, you’ll be guided through 2-3 dives, with each location offering a unique underwater canvas. The guides, such as Cristina and Takashi, are praised for their patience, helpfulness, and knowledge. One reviewer noted Cristina’s helpfulness in English, which eases communication for international travelers, while Takashi’s friendliness made the dives more enjoyable.

The dive duration is typically 20-25 minutes per site, which is standard for safety and enjoyment. The focus is on vibrant reefs and abundant marine life, including occasional sightings of turtles, small sharks, and even the rare chance of seeing a larger fish like a shark or a snake eel.

Equipment & Comfort

The tour provides full rental gear, including tanks, weights, and towels, making it easy to just pack your swimsuit and dive log. If you wish to capture underwater moments, rental cameras and SD cards are available for an extra fee—though bringing your own is always an option.

The boat is described as clean, well-equipped, and comfortable, with amenities like hot showers, toilets, and cabin heaters. In winter, the staff takes extra steps—using boat coats, cabin heaters, and engine heaters—to ensure warmth and comfort, as the sea temperature stays above 22°C.

The Authenticity and Additional Insights from Reviews

Reviews portray this tour as well-organized and professional, with many highlighting the friendly and knowledgeable staff. Sammi, for instance, appreciated the direct transport from her hotel and the friendly guides. One reviewer, Jessica, pointed out that although the guides were very experienced, their English wasn’t perfect, which could pose minor communication issues above water but not underwater.

Another key insight comes from the reviewer who was disappointed about the short dive times and crowded boats with mixed groups, including snorkelers and less experienced divers. This suggests that if you prefer quiet, extended underwater time, you might want to plan accordingly or ask about the group’s composition beforehand.

Several reviewers praised the diverse marine life and beautiful coral reefs, with sightings of small sharks, sea snakes, and turtles. The guides’ attention to safety and comfort was frequently mentioned, making even nervous divers feel reassured.
