I was not sure if my children would be able to keep up with the tour as a family, but thanks to the very friendly, kind and knowledgeable guides, I really enjoyed it. I had very precious memories of my family who had just taken many photos. Thank you very much.

I've never swam in the ocean before, and I've enjoyed Kanazuchi, which is only capable of flopping. Our guide pulled us offshore with a float and we were able to see a variety of coral reefs and fish. When I was first told to jump into the Blue Cave, I was very surprised, but I had a difficult experience. Next time, I will do a warm-up exercise before I hope.

정말 행복한 하루였습니다! 투어 가이드 분들도 모두 친절하셨고, 일본어가 안되서 걱정 많이 했는데도 불구하고 영어로 투어 신청하니 의사소통이 되서 정말 다행입니다! 차로 가는 동안 계속 수다 떠느라 시간 가는 줄 모를 정도로 친절하고 친근합니다! 특히 저희 가이드셨던 Iroha님을 칭찬합니다! 차멀미가 심한 저의 아내가 차멀미도 하지 않을 정도로 운전도 세심하게 해주셨고, 스노클링 할 때도 스팟마다 주의점이나 볼 만한 해양생물들을 알려주셔서 놓치지 않고 볼 수 있었어요! 그리고 특히 바다거북이!! 볼 수 있을 줄은 꿈에도 몰랐는데, 행운이 따라줬는지 볼 수 있어서 다행이었습니다😄😁 이것도 Iroha 가이드님이 먼저 말씀해주셔서 놓치지 않고 볼 수 있었어요! 종합적으로, 완전 추천합니다! 특히 스노클링 초보 분들도 부담 없는 코스니까 이시가키에 들르셨다면 꼭 즐겨보세요! It was truly a wonderful and unforgettable day! All of the tour guides were incredibly kind and friendly. I was quite worried because I don't speak Japanese, but thankfully we booked the tour in English and had no trouble communicating at all. The drive never felt long because we spent the whole time chatting with our guide, who was warm, approachable, and made us feel completely comfortable. I would especially like to compliment our guide, Iroha! My wife usually suffers from severe motion sickness, but thanks to Iroha's careful and smooth driving, she felt perfectly fine throughout the trip. During the snorkeling tour, Iroha also explained what to watch out for at each spot and pointed out various marine creatures, so we didn't miss any of the highlights. And most importantly—the sea turtle! We never expected to see one, but luckily we did! 😄😁 Iroha spotted it first and let us know right away, so we were able to enjoy the moment without missing it. Overall, I highly recommend this tour. Even if you're a beginner at snorkeling, the course is easy to enjoy and not intimidating at all. If you're visiting Ishigaki, this is definitely an experience you shouldn't miss! Thank you, Iroha, for making our honeymoon in Ishigaki even more special!

Fujiwara no Kazemai guided me on a snorkeling tour of the Blue Cave. The tour was friendly but also calmly explained when sea snakes and big fish came out, which made me feel very secure. The restaurant they recommended after the tour was also very good, with quick reservations.

Accommodated us with an alternative tour when our first choice was cancelled due to dangerous winds. Communication was very easy, even in English. All of the staff were friendly and fun. Akari was our guide while snorkeling. She was awesome. Kept us safe while showing us all of the cool spots at the Blue Cave. She towed 2 children the entire time…well done girl. She was very helpful with me looking for something that i thought I left behind. That was above and beyond her job and I really appreciated it. Highly recommend this tour group and Akari. Snorkeling at the blue cave was the clearest water and most abundant fish that I’ve ever snorkeled in around the world. Worth it.

Blue Cave exploration & snorkeling. The Blue Cave feels compact compared to the cave of the same name in other areas. The main course is snorkeling. It guides you along the trench, so you can feel the extraordinary floating feeling combined with transparency in deep water spots. The guide is friendly and entertains you with talks so you don't get bored on the way to and from the car. We had several children participating, including ourselves, but they are very supportive and I think families can participate with peace of mind. It is recommended to take extra care to protect against UV rays, as sunburn can occur even in cloudy conditions.

This is my first time snorkeling. I participated with my children, but they guided me carefully and I could enjoy it with peace of mind. I also met sea turtles and swam with them. It was one of my best memories of Ishigaki Island.

I joined him for the first time in his life. He was afraid of the sea & not good at swimming, but this tour looks fine! I read the word of mouth and decided. As a result, the guide followed us from start to finish and we enjoyed it together. It was a satisfying tour that I used my strength but was glad to experience. I was also grateful for the information about the island such as delicious shops and fruit♡

I really enjoyed the snorkeling experience on Ishigaki Island!! The guide's brother was cheerful and enlivened throughout, and the whole family really enjoyed it. Even during the trip, they told us about the history of Ishigaki Island, tourist attractions, and the uniqueness of the island, and they had a great time outside of the activities. They were also very careful about the safety of the children, so I could participate with peace of mind as a parent. I also had a lot of knowledge of the island and was happy to learn so much about its charms. If you are going to snorkel on Ishigaki Island, I highly recommend this tour.
