Our actions

All staff regularly organise beach cleanings and port cleanings in both Aka island and Naha.

We occasionally pick horn drupes which eat up corals, and turn them into craft accessories.

SDO is a certification for all divers that oversees safety in diving in Okinawa.
All of our branches are acknowledged by it.

Our instructors undergo ongoing rescue and safety trainings that abide to SDO’s guidelines.
