Blue Cave Snorkeling
This is a snorkeling tour around the popular and unexplored “Blue Cave! As the name suggests, the inside of the cave is shining blue. Let's swim with a lot of fishes!
Landing & Snorkeling at Phantom Island
Phantom Island” is a sandy island in the ocean on the west side of Ishigaki Island. The name comes from the fact that the shape of the island changes depending on the tide level. The surrounding sea is called “Seokusei-shoko”, one of the largest coral reefs in Japan! It is like a natural aquarium.

5.00It was my first time to experience snorkeling, but the guide was more friendly and took care of my physical condition as appropriate, so I could participate with peace of mind. Also, we were very grateful to have a transfer from the hotel.

5.00It was a very good memory of Mr. Hayabira's trivia and talking to others. Of course it is important who you go with, but I felt it was equally important who gave the lecture, so I would like to ask Hayabira-san again!

5.00It was my first time snorkeling! I didn't have confidence in swimming, but the staff always had a float, so I got caught and pulled by it The staff were very friendly and always checked my physical condition, so I was able to participate without any worries! Next time I come to Ishigaki Island, I'll join again!
It was a great tour to see the sea and the road.

5.00It was my first time snorkeling, but I was guided carefully and enjoyed it with peace of mind. The explanation of the fish was easy to understand, and I was impressed to see creatures not usually seen such as sea turtles and sea snakes! They told us about recommended shops and sightseeing information while we were traveling, and we could see peacocks along the way. I'm very satisfied to enjoy Ishigaki Island more!

4.00I participated alone. I was very anxious because I was not good at swimming, but the staff was kinder and I could snorkel with peace of mind! Thank you very much.
It's really too beautiful to see the sea, and it's full of rain.

5.00Even if Japanese is not so good, swimming is so bad, you're OK!👍🏻 Very wonderful experience! とてもお綺麗で、英語もお上手で、最高のガイドさんです!🩵💙 ーーーーーーーーーーーーーーーーー I was worried that I could hear Japanese, but I was worried that it was difficult to speak Japanese, but Akari guided me well and made it fun even if I couldn't swim.
