The staff were friendly, cheerful and fun! ◆Balas Island Snorkeling It was amazing to see so many table corals! Physically, I had a lot of fun without any problems. It was amazing to see the staff, Mr. Kaji, diving deep in his snorkeling gear and taking pictures of us. lol ◆ Mangrove sup To be honest, the 28-year-old was physically tough on a small woman who usually works at her desk, but the staff, Koma-chan, was waiting for me to teach me some mangrove trivia and said, "Good lad!" I was happy to hear that they complimented me. The staff, Sei-chan, pulled me when I just couldn't catch up with the headwind and current, which was a big help. It was interesting to see some goby ones and crabs at the base of the mangrove! Canoeing might be better for the physically weak lol

It was my first time canoeing with my wife and I, but thanks to the easy-to-understand guidance from the guide and the support we received even after we got out on the river, we really enjoyed the mangrove forest cruise! It was so much fun that I almost bought a canoe. I think this is a great activity where you can easily experience the nature of the stone walls. Thank you very much.
It was an unforgettable graduation trip!

In canoeing, they taught me how to row carefully and kept pace, which I really enjoyed even in my first experience. They also gave us a detailed introduction to the plants and we were able to enjoy the mangroves gracefully. The weather was not good and the place changed, but we could see fish on many reefs and enjoyed beautiful sea views throughout. It was my first time snorkeling and I was confused by the snorkeling and found it difficult at first, but I was able to participate with peace of mind because my guide was always watching over me and talking to me. We were so happy to have so many wonderful photos taken of us, both canoeing and snorkeling, not only of us but also of the scenery! He also told me about various recommended spots on the way to and from school, which was very helpful, and all the recommended places were good and I fully enjoyed the stone walls! I hope to participate again at a different time!
Fab experience!

We had a fabulous experience on Ishigaki Jima! My husband and I absolutely loved our day. We kicked off the morning with snorkeling, and although it was a bit chilly, the water was warm, clear, calm, and making it perfect for spotting heaps of fish and even a couple of sea snakes. In the afternoon, we went stand-up paddleboarding (SUP) through the mangoves, which was equally stunning. A massive thank you to Diego, who captured so many incredible photos, and to the entire team whose energy and enthusiasm made this tour unforgettable. We highly recommend this tour to anyone visiting Ishigaki Jima!

This was incredible. We have been in Japan for three weeks and now sadly at the end of our holiday. Japan has been amazing but this was voted our favourite as a family. The guides were awesome and all activities well organised and fabulous. The snorkling and phantom island were mind-blowing and what a chance of a life time to see a coral reef. Our guides also took photos and shared (without additional charge). Would highly recommend.
A fun and meaningful tour

The tour was a meaningful and enjoyable experience. The good points were that we could see the magnificent view and experience something out of the ordinary. While snorkeling, we could see colorful fish and coral reefs, and the Phantom Island was a photogenic spot, so the tour guide took lots of photos for us. At the mangrove SUP, we were able to learn a lot about the secrets of the mangroves while getting some exercise. Please note that the sea in March is cold.
