Tour guides were professional and prompt. Lunch was quite good. Actual snorkeling was quite lovely, however booking with Tripadvisor was a nightmare. One person in my party cancelled a few days before the trip and the website completely glitched out and would not allow me to cancel one of the tickets in my party. Tripadvisor referred me to the tour operator and they told me it is completely out of their hands. Burned the cost of one ticket. Won't be booking with Tripadvisor ever again.

I have never seen so many varieties and colorful in one place. The coral were beautiful. The entire trip was very well organized with a helpful, friendly and knowledgeable crew. They had a warm outdoor shower to rinse off, towels and and area I could change my clothes if I wanted to. The fish were so abundant and beautiful I wished I had a camera. They thought of that too and offered me an underwater camera to use with a reasonable fee. At first there seemed to be a lot of people but it was do well done that once We got in the water you could hardly notice. On previous snorkeling trips the coral were badly damaged but that was not the case here. It was a perfect way to spend our last day in Japan.

Tour was great - we had lots of fun! At the beginning there wasn’t much information and the crew took some time to pack and load the boat. But arriving to the first stop - it was amazing! Lots of beautiful and colorful fishes and also some sea turtles decided to join the party!

This snorkeling was great! We went to 3 spots rhe reef is really big so plenty of space to spread out and explore! Unlike other tours where you are on top of one another

The organizers picked us up at our hotel. The helpers were efficient and took us to a nice place to see turtles and sharks. Lunch was offered. It was ok, but would recommend bringing your own. The curry really didn’t go with the seas.

Would not recommend with this tour agency. We contacted the day prior to confirm if the tour was going ahead because the next days forecast was pouring rain and strong winds. It was noted to the tour group my friend would not feel safe in that weather to snorkel and as myself an experienced snorkeler I already knew by the visibility rating and swell it would not be a good day to go and waste of money. The tour agency refused to refund the money the day prior & when we tried to say how unsafe it would be to snorkel in these conditions they still refused and stated the tour would be going ahead no matter conditions. This we felt is a really dangerous attitude and unsafe for travellers to go with this tour agency. Safety should always be paramount than money for travellers! We lost both of deposits of over $200 but just simply wasn’t the risk of getting smashed by rain and choppy seas all day.

Long boat ride out, but the scenery makes it go by fast. But, if you're prone to seasickness, take your meds.

I went in March so the water was still a bit fresh/cold. The fish were beautiful. The coral reefs were massive. It was really good value for the experience. Do keep in mind if you are snorkeling you use a lot of time waiting for the scuba drivers to complete their dive. They were able to accommodate a hotel pick up and return drop off which made this easy. I see some bad reviews online that scared me a bit. I am happy with my experience. If you are a germaphobe I would skip this experience.
