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.

Since I was traveling alone, other companies were having trouble booking more than two people, but Pipi was really grateful to be able to participate alone. I didn't see any sea turtles this time, but I had a great time seeing many beautiful fish in the beautiful sea. The staff were also kind and I enjoyed it with peace of mind even if I participated alone. I'm going to join you again! Thank you very much.

I was looking out at the sea on the boat without snorkeling because I have a chronic illness, but I was very satisfied because I was able to sit in a place with a good view and learn about a good local rice restaurant

I was worried about seasickness, but it was so short that it wasn't at all. Snorkeling ... was amazing to see the sea snakes. The tour guide is also very firm and secure. The weather on the phantom island was good and I was able to take beautiful photos and had a great time. I recommend it.

It 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.

It 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!

It 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 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!

I 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.
