Went with a group including a child for snorkeling. Great staff, very attentive. Great environment with plenty of fish to see and clear waters. We were lucky enough to see two turtles as well as clownfish.

This is such a great tour - Everything is so well organised and the snorkelling spots are amazing. The staff also accomodated a vegetarian meal for me which was great. I would definitely recommend this to anyone staying in Naha!

This was a fun and amazing snokering trip. i enjoyed every moment. All the staff were attentive, professional and full of fun. Special kudos to Dora. She's full of energy and is the best guide! The water of Kerama Islands is truly amazing. I strongly recommend a full day trip (with 3 dive sites) instead of half day. The half day trip with just 1 dive site would have been too short. I was just warming up after the first dive site and glad that I went for a full day.

The staff was great and very friendly. Most of the boat crew could speak or spoke some English so it made the experience better for my friends and are who are from the US. We choose the snorkeling experience and it was everything I hope for we were fortunate enough to see a sea turtle and a moray eel. But everything else was amazing. The coral reefs were amazing and allowed you to get really close to fish that inhabit the coral. They provided lunch on the boat which was a choice between two bento boxes and for pre made food Japan does it best. It felt like the perfect sized meal after swimming for around two hours at the first two locations. 100% would recommend trying this experience.

This tour is well organized from shuttle pickup to boxed lunch and all the necessary things that you might need during this tour. The staffs were super helpful and nice and guide us when we are in the water. Pictures that they took while we were snorkeling are valuable and gave us something to remember for. Overall, a very enjoyable experience!

3 snorkel sites, amazing clear water with huge coral and fish. Experienced guides fluent in English. Lots of safety protocol (3mm full wetsuit or life jacket is required). Cold water throughout, and tasty lunch bento. About 30-40 other snorkelers on the boat this time but they split up the group and it didn't feel too crowded in the water

This was an extremely well run operation and felt safe. We got to see many of the islands and some beautiful waters and fish. I am not sure if it is always a bit rough but it was on the day we went. My only negative comment is that it was a larger group than I am used to going out with and there was more waiting around and lining up for facilities.
