Welcome to Piranha Divers in Okinawa.
Haisai*! We are Jan and Tomoko, the proud owners of Piranha Divers. My passion for diving began in 1999 when I took my first dive in a chilly German quarry. Despite the cold, I fell in love with the underwater world and became a diving instructor. My journey took me to Egypt, where I met Tomoko, and then to Greece, Australia, and Thailand. We married in 2007 and moved to Okinawa soon after. In 2009, we realized our dream of opening Piranha Divers as a family-run diving school.
While I’ve earned the ratings of SDI Instructor Trainer and PADI Master Instructor, Tomoko is the heart and soul of Piranha Divers, managing our daily operations. We’re located in the stunning northern part of Onna, an ideal spot for diving and raising our kids. We’d love to welcome you here and share our passion for the ocean with you.
Piranha Divers is an SDI/TDI 5 Star Resort and a licensed limited liability company, fully authorized to offer commercial scuba diving services in Okinawa.

Our Diving Services
Piranha Divers is a diving school in Onna Village that focuses on teaching divers from beginners to Instructors. We offer fun dives and excursions, with a strong emphasis on educational programs.
Our choice of dive sites considers the diver's experience, wind direction, and daily weather conditions. While boat diving is popular in Okinawa, it often requires an early booking to secure the seat. Therefore, we also provide plenty of shore dives, offering more flexibility for teaching and exploration.
Piranha Divers offers a range of services, fun diving for certified divers from the shore or boat, equipment rental service for those who want to dive independently as well as annual equipment maintenance for brands such as DiveRite, Apeks and Aqualung
Environmental friendly diving at Piranha Divers: We teach and dive neutral buoyant. We occasional organise underwater cleanups and follow the Greenfins guidlines on not touching, taking or feeding marine animals.
