Natural Blue Diving and Rental

Located in the Kunigami District of Okinawa, Natural Blue operates with a deep commitment to marine science and environmental stewardship. The centre is built around the principles of sustainable development, incorporating active coral planting and seabed cleaning into their approach to diving.

You can choose between two distinct access points: the Maereda Misaki boutique, which offers immediate proximity to the reef, or the Yomitan location, which provides additional facilities such as warm showers and childcare services. This dual-location setup allows for flexible planning depending on whether you are looking for direct site access or more extensive shore-based amenities.

The team is composed of highly qualified professionals, including instructors and examiners certified through PADI, CMAS, and NAUI. The centre's leadership brings a scientific perspective to diving, with the owner holding expertise in marine sciences.

Instruction is delivered in both Japanese and English, ensuring clear communication for international divers. To maintain a personalised and serene atmosphere, the centre focuses on private charters rather than large groups, with a maximum ratio of 10 divers per guide. They also offer specialised programmes for divers with disabilities and online courses for those looking to prepare before arrival.

Natural Blue provides a comprehensive range of training through PADI, CMAS, and NAUI. Beginners can start with the Open Water Diver course, while more advanced divers can progress through Nitrox, Rescue Diver, and Divemaster certifications.

The centre also offers specialised CMAS training, including CMAS Instructor, CMAS Rescue Instructor, and CMAS Divemaster programmes. For those looking to move into professional instruction, the full range of course titles is available upon request.

For those preferring to use their own kit, the centre offers a self-rental service for experienced divers and snorkelers. Full equipment sets are available for hire, including BCDs, wetsuits, masks, fins, and boots.

Individual items, such as masks or fins, can also be rented separately. The centre maintains an oxygen safety station on-site for use during dives. Parking is available at the locations for a small fee.

The waters around the Blue Cave are home to a variety of fish species that inhabit the reef structures. You will find a diverse range of reef fish moving through the water column and around the coral formations.

The marine landscape is defined by its vibrant life, with many species benefiting from the centre's ongoing coral conservation efforts. The biodiversity outside the cave provides a rich environment for observing typical reef inhabitants.

Macro life and smaller organisms can be found throughout the area, providing plenty of interest for those who enjoy observing the finer details of the reef ecosystem.

Divers should be aware that reef currents and occasional swell can be present in the area. The specific conditions at the Blue Cave and surrounding reefs can change based on local swell activity.
