About the owner of Natural Blue
The owner of Natural Blue had sailed around the world in one week and is one of a handful of instructors in Japan rated as an examiner who can certify diving instructors and act as a test official. The owner is also a JASA Instructor II certified by the Japan Sports Association. This is different from instructors simply running diving shops or engaged in the activities based on personal interest. This level of certification is given to instructors who have a profound understanding of how the local community coexists with the natural environment, who are highly aware of safety and equipped with excellent crisis management skills. In addition, the owner has been working as a lecturer in a school specialized in ocean sports. Therefore, the entire staff can provide professional, interesting, fun and friendly instructions. We are also a highly reliable business regarding safety. We are certified to instruct the disabled and can lead poor swimmers safely into the ocean. Customers who cannot swim well can join any of our courses at ease.

Status of the diving shop
Many people who have experienced diving gave comments such as, “It was scary when we suddenly had to enter the water from the boat,” or “my ears hurt when I was forced to dive deeper.” Their diving experience appeared to leave only bad impressions. As instructors, we were saddened to hear this. Enabling participants to feel safe and at ease should be our priority but was evidently neglected. We maintain courses in small groups and provide careful instructions, creating a once-in-a-lifetime memory rather than leaving a bad taste in mouth. Our detailed and careful lessons on diving techniques have earned great reviews. Please relax and enjoy scuba diving and snorkeling in Okinawa when you join one of our courses.

The Natural Blue ideals
Natural Blue actively contributes to society by participating in activities such as local cleaning, ocean conservation and ocean education initiation.
