Although we changed our activities due to the large tide, we were able to book the next day because we wanted to see the underwater view of Barras Island. Yume, our guide on the day, showed us how to snorkel and where we could see fish, and although we didn't see the sea turtles, we were able to see the clownfish and moray eels and fully enjoy the coral world! Thank you for changing my schedule!

It was my first time snorkeling as a child, but the guide made it a lot of fun! Thank you for being my guide, ok? There are several guides on each boat, and everyone was comfortable and positive to the end. The whole family is happy to see so many fish in Balas Island with beautiful coral!

We were the only participants, so we were very pleased with the resourceful nature of the tour! Our guide Okun was very kind in guiding us on the tour! I want to go again.

We couldn't go to Barras Island because of poor sea conditions, but we snorkeled on the star sand beach as an alternative. Thanks to Okun leading and pulling me, I was able to enjoy the beautiful sea without getting tired. The best thing was that I was able to leave the child in charge with peace of mind because he also had a supportive background. Both of them were always talking to their children, so I was able to snorkel with great peace of mind. Thank you for the beautiful photos too. I'd like to ask you again.

Snorkeling beginners. The last snorkel on the main island of Okinawa was a revenge snorkel because the weather was bad and it was disappointing. I was happy to see all the sea turtles, sea snakes, coral islands and cute tropical fish in a short time. At first I thought I had a short time, but by the time it was over I was exhausted.
