Reviews: 2-hour diving and snorkeling experience at the blue cave in Okinawa city, Japan [blue cave snorkeling/diving/English and Japanese instructors/shore entry to avoid seasickness]

Guest User2026-04-30

Everything was well organized. I was alone with the instructor. Since this wasn't my first dive, I enjoyed the clear water and the view of the cave's depths without worrying about whether I was doing everything correctly. Special thanks to the instructor for not bothering me too much, knowing my experience.

Reviews: 1-hour certified scuba diving in Okinawa, Japan [Swim with giant whale sharks, Chinese-speaking instructor, underwater photos included, Naha city to Chatan hotel transfers]

Guest User2025-04-21

A truly unforgettable experience! The whale sharks were enormous and awe-inspiring. Swimming up close with them is a completely different experience from seeing them in an aquarium. The underwater safety netting made it very safe, even for non-swimmers. Our instructor, Chobi, was incredibly enthusiastic and humorous. I'm quite satisfied with the photos he took. Two suggestions: first, when taking photos, try to maintain a slightly larger distance to capture the difference in size between the whale shark and a human; second, the itinerary was a bit rushed, and I hope there will be some time to swim after seeing the whale sharks.

Reviews: Okinawa City, Japan Experience Diving Scuba Diving 2 Hours [Blue Cave Boat Experience Diving (Free Photo Shooting and Transfer)]

Guest User2026-03-18

I arrived about a week before the peak season, so I was searching online, worried that I wouldn't be able to swim or participate in activities, when I discovered this place!!! Scuba diving was on my bucket list, and I was able to fulfill it here. I don't think I will ever forget the experience of diving inside the Blue Cave. Koreans, please make sure to book with this company. There are Korean staff members, and they are incredibly kind. I was scared since it was my first time diving, but they treated me with such kindness and warmth. Thank you again.

Reviews: 3-hour diving and snorkeling experience in the Kerama Islands of Okinawa City, Japan [summer-limited snorkeling activity/pickup and drop-off at designated locations in Naha City]

Guest User2025-10-31

The tour group consisted of 4 people plus crew, totaling 6 people, with approximately 20-25 tourists, which was sufficient to ensure everyone's safety. The tour leader was fluent in Japanese and Korean, and there was also an English-speaking staff member and a Taiwanese staff member who spoke Mandarin. All details and precautions were explained in four languages. The snorkeling area had safety boundaries, which made me, a not-so-swimming person, feel very safe and secure, and the experience was excellent. The underwater photographer was a very good photographer, but due to the large number of people and their movement, he might not be able to take photos of everyone. If you see him, remember to stop him and ask for your picture! Another very important point is that since it's a fast boat, if you have a history of seasickness, remember to take motion sickness medication!
