We went diving in January on the off season and we were fortunate enough to get our own private diving session. It was my first time diving but our instructor Higa made sure that I could understand all the basics and was extremely helpful during the whole dive. All the equipment is provided and the whole trip is recorded so you can share the experience later. You will also get a chance to feed tropical fish and have a whole school of fish swimming around you. The staff was very kind and helpful to me since I struggle with speaking Japanese. Okinawa diving suns offers a unique diving experience of the blue cave and I would recommend the experience to anyone.
