This diving experience was a wonderful memory. Many thanks to coaches Tommy and Jimmy, who taught in Cantonese throughout, were professional and friendly, and helped us take many beautiful photos. We had a great time. Okinawa's glass-like sea truly lives up to its reputation; the Blue Cave was breathtakingly beautiful, with clear blue light reaching the bottom. It was hilarious to queue up for photos underwater for the first time! The coaches provided attentive one-on-one guidance, and my 15-year-old son felt very safe and enjoyed his first diving experience. The entire coaching team was full of sunshine and energy, very attentive, stylish, and chill. After the activity, we could walk to the shop to shower and change, which was convenient and comfortable. Grateful for all these wonderful experiences.
