Diving with Piranha

Jan Claudius Weirauch Piranha Divers Okinawa piranha divers tripadvisor

This is me, Jan, and my wife Tomoko. We’re the founders of Piranha Divers, a scuba diving company in sunny Okinawa. We provide a service in both English and German to foreigners visiting or living in Okinawa.

I first started diving in 1999, basically as soon as I was old enough to put on a scuba tank and stay underwater. That first dive into the deep was in a chilly German quarry, but the cold experience didn’t put me off and I’ve had a passion for diving ever since.
Later I became a PADI diving instructor and my work took me to Egypt (where I met my lovely wife), Greece, Australia and Thailand, before I settled in Okinawa with Tomoko and the goal to establish a dive service, which we did in 2009.

We would love to welcome you here too, where you’ll experience the best diving in Japan (which also means strict, modern safety standards), and fantastic sub-tropical island life – lots of sun, stunning beaches and crystal clear warm waters (25–30°C most of the year).

Also, scuba diving in Okinawa means endless reefs, walls and caves, a huge WWII wreck, and incredible sea life – from tiny strikingly-colored nudibranchs to rays, turtles and tuna.

We believe you’ll love diving in Okinawa with Piranha Divers because we offer smaller dive groups and a more personal service than you’ll find elsewhere on the island. And if you’re a complete beginner, an instructor or anywhere in between, we can tailor-make a dive program to suit your needs. Also, diving with us means a full range of modern rental equipment – maintained and regularly updated.

Look forward to seeing you,
Jan and Tomoko

Okinawa and diving

okinawa map

Okinawa is an island in the Ryukyus, a chain of volcanic Japanese islands that stretch southwest from Kyushu to Taiwan, and the main island of Japan’s Okinawa Prefecture. This island, which is only about 112 km long, is where Piranha Divers’ shop is located, about half way up in fact (so perfect for all directions).
While Okinawa has a great variety of incredible dives, we try to focus on servicing the northern part of the island where there’s more nature to see and fewer people to bump into.

Diving in Onna Village
Are you looking for a day of “easy” diving? Maybe your last dive is already some time ago. Or are you still learning how to dive? If this sounds like you, then Maeda Point, and the famous Blue Cave with its beautiful rock formations and very blue water, is a truly great dive location with a moderate depth of 20 m (60 feet) and minimal to no currents.

But if you’re looking for something a little more challenging, we’ll take you to Manza where there are several great dive spots with incredibly varied marine life and a continuously changing topography. Frogfish at Nakayukui Point, turtles and white-tipped reef sharks at Overhang Rock, and grey reef sharks at Horseshoe are just some of the sea creatures you might get to see, as well as lots of garden eels and fan corals at the magical Manza Dreamhole.

Diving in northern Okinawa
If you’re interested in adventure, or history, and have at least 50 dives under your belt then we think you would love a day trip to the wreck of the USS Emmons. It’s an American Destroyer around 40 m down off the coast of Kouri Island and is an eerie reminder of Okinawa’s darkest hour during WWII.

Continuing the adventure, the most northern point of Okinawa offers Cape Hedo, a unique dive location where the Pacific Ocean proper and the East China Sea meet to create an incredible mix of marine life and diving intensity. Experience vibrant reefs, occasional strong currents and the famous Hedo Dome, entered from underwater before an inside ascent where you may just find traces of prehistoric life.

Where we dive

The northern parts of the island are nowhere near as developed as those further south. Which is why we like them. Not only do you get to experience some of the hidden adventures Okinawa diving has to offer, you also get a glimpse into a more traditional Okinawan lifestyle.
