As for reservations of activities on Okinawa「OneTwoSmile ACTIVITIES」
Northern Central
First-timers are welcome! Experience diving at the spot with the highest coral abundance in Onna Village, providing high visibility!!

Experience diving at the spot with the highest coral abundance and excellent visibility in Onna Village! It is a recommended plan for first-time divers as it is a shallow dive site. This spot is rich in small tropical fish and has a variety of clownfish species. With calm waves, the tour has a high success rate and provides a safe and enjoyable experience for those who are not confident swimmers, beginners, and children! Since it can only be reached by boat, there are fewer people, allowing you to enjoy a comfortable diving experience.

With over 20 years of accident-free operation certified by the Okinawa Prefectural Public Safety Commission, our staff consists of licensed divers. Our facility offers free use of showers and lockers, eliminating any additional costs. Participants aged 10 and above are welcome to join. Our boats are equipped with warm water facilities, and complimentary thermal coats are available for use.

*Please note that reservations are required for a minimum of two people.

Customers who weigh more than 100 kg cannot participate because we cannot prepare the equipment, so we appreciate your understanding.


You don't have to worry about the language, because in the practice the staff will use simple English conversation words while showing photos that are explained in Chinese, Korean and English.
