Experience diving (boat holding) plan in the popular NO1 blue cave on the main island of Okinawa. A fantastically shining blue cave created by nature. In addition to the shining cave, you can enjoy colorful tropical fish, coral reefs, and dynamic underwater scenery outside the cave. I thought of a way to make my first diving comfortable and fun so that I could convey the impression that it was the best in the sea! It is an experience that excites and excites the mind in safety and security. 1 minute walk from the shop to the port. Depart on a special marine boat and head to the cave while taking a pleasant breeze over the crystal clear water. There is no need to move stairs with heavy equipment on the back or walk around dangerous rocks. There is no need to swim desperately for long distances from the beach entry location to the blue cave. Boats moor near the cave entrance. The long-awaited blue cave is waiting for you! "One group complete charter system" Even if you are not diving for the first time, it is okay. A dedicated instructor will support you from the customer's perspective. One instructor will be in charge of chartering up to two guests and a small group. Experienced guides will guide you to the Blue Cave safely and happily. Please leave your first dive in peace.
