The Famous “Blue Cave” – One of the Most Popular Spots on Okinawa Main Island! Inside the approximately 30-meter-long air dome, sunlight pours in from the entrance, illuminating the clear blue seawater and creating a glowing blue surface. With your Blue Cave Snorkeling Tour, you can experience this mystical and breathtaking seascape. During the tropical fish feeding, you’ll be surrounded by so many fish that you might not even be able to see in front of you! A fully-private tour for groups of 3 or more people! The shop is a completely private tour for reservations of 3 or more people! So you won't have to wait for other customers or the shop's schedule, and you won't be left behind at the beach!

Definitely the highlight of our trip! Our tour guide was amazing! I wasn’t expecting to see all of the beautiful colorful fish that I did. The water was so clear.

Very disappointed. We had planned my friend and I to discover the blue cave in Onna and we were simply refused to do the activity according to our age. Like we were too old. We are 63 and 64 years old and the maximum age was 65 years indicated on the website. Since no news from TripAdvisor where I explained my dissatisfaction. We wanted and that’s the least we could get back! But to date no answer. I would not recommend this site!

Our guide Kazuki was great! Over our 45 minute experience he showed us different sites and while also being flexible with our abilities! (I can’t swim for context) Overall great time and would definitely do it again!

It was my first time scuba diving, and I was entertained from start to finish! I was impressed by the sea in Okinawa. Thank you very much.

We were excited to book this excursion as we had read so much about it. However when we got to location their was a language gap with providers which we were used to being in Japan but google translate helped. However my wife misread the medical release form and thought she had to note all medical prescriptions she had ever taken including past prescriptions. When we turned paperwork in, the provider in broken english asked if she had high blood pressure and my wife said no but she had taken prescriptions 10 years ago for it but currently did not have too. This was done through google translate. Young man told her she could not go via google translate again and my wife explained again that she was fine and that we had snorkled all over the world without ever bei g told we could not go because of medical. They basically said sorry you can’t go and asked if I wanted to go without her. I told them that I would not go without her and asked for a refund which I was told again through their google translate that one would be issue backstage. I understand liabilities and policies but this was clearly a miscommunication and even though we tried to communicate that, they would not have it and would not let us go. Now they are communicating back to us that no refund will be issued because site clearly states that “no refund will be issued for medical reasons”. Not impressed with their customer service nor their refund policy. Will not use this service again.
