Being January, the middle of winter, I was worried about the cold and hesitated, but I chose this tour and it was absolutely perfect! I received kind instructions via email and WhatsApp the day before the tour, and they provide all snorkeling equipment (mask, wetsuit, diving boots, and short fins), so all you need to bring is a swimsuit and towel. We met at the 2nd parking lot of Shigi beach, put on wetsuits, moved to the beach, listened to some precautions, and then entered the water to put on the remaining equipment. After receiving the meticulous service of providing anti-fog medicine for the snorkeling mask, the tour begins in earnest! The underwater environment is clear and clean, so you can enjoy it with a clear view!! I was able to spend a fun and happy time meeting sea turtles and tropical fish like Nemo while listening to the kind and passionate guide Mayu's skilled leading and guidance!!! In particular, guide Mayu showed great activity with excellent English skills and constantly checking the safety of the group, as well as leaving wonderful memories with amazing underwater photography, and it was a perfect experience with the added consideration of providing warm water after the tour!!!! Thank you Mayu! If you want to go on a snorkeling tour in Miyakojima, don't hesitate and apply here! Definitely!
