I was worried about the cold as it was January, the middle of winter, but I chose this tour after much deliberation, and it was absolutely perfect! The day before the tour, I received kind instructions via email and WhatsApp. All snorkeling equipment (mask, wetsuit, diving boots, and short fins) is provided, so you only need to bring your swimsuit and a towel. After meeting at Shigira Beach parking lot 2, we put on our wetsuits, moved to the beach, listened to some precautions, and then entered the water to put on the rest of the equipment. The tour officially began after receiving the thoughtful service of anti-fog solution for the snorkeling mask! The underwater environment was clear and clean, allowing for an enjoyable experience with excellent visibility!! We had a fun and happy time encountering sea turtles and tropical fish like Nemo, guided by the skilled leading and instructions of our kind and passionate guide, Mayu!!! Guide Mayu, in particular, showed outstanding performance with excellent English skills, constantly ensuring the safety of our group, and creating wonderful memories with amazing underwater photography. After the tour, the thoughtful provision of warm water made it a truly perfect experience!!!! Thank you, Mayu! If you want to do a snorkeling tour in Miyakojima, don't hesitate and book here! Seriously!
