In 2018, I arrived in Okinawa and set off on my Japan diving journey. I settled there temporarily, living and working in Okinawa. Along the way I got to know many Japanese divers, and one day a seasoned diver introduced me to a very special izakaya called「クマノミ」— run by a couple who were passionate about diving. It has since closed.
For me, it was a door thrown wide open into an undiscovered world of Okinawa diving. The owner told me they had been diving in Okinawa for at least 30 years — diving from their youth into old age, travelling all over the world to dive — yet Okinawa remained their favourite. Both she and the regulars told me that Okinawa was far more than just Kerama; there were countless places waiting to be discovered.
In the corner of the izakaya, a television played footage they had shot underwater. I witnessed a scene I will never forget for the rest of my life: a manta ray surged through the water at high speed and leapt clean into the air. Before I even had time to react, a regular sitting next to me said, "Pretty cool video, right?" I said it was absolutely incredible, and asked whether it had been filmed by a diver here — and received an answer that completely floored me: "Yes — that was me who filmed it!" I couldn't hide my excitement. I peppered him with questions: How did you happen upon that moment? Where was it filmed? How many times in your life have you seen something like that? He answered every one of them with great enthusiasm and told me that Okinawa was truly spectacular — that I absolutely had to go and explore it for myself, and then share it with other divers. That was also when he first mentioned the dive site I want to share with you today: Triangle.
Dive site markers densely packed on Google Maps
Before I moved to Okinawa, I had only dived on the main island once — at the Blue Cave. It's a classic spot, and I remember it vividly: Clownfish right there in the shallows, utterly adorable, and coral reefs of breathtaking beauty. But after moving there, I learned that Japanese divers visiting Okinawa almost always head to the Kerama Islands to dive. In Kerama, visibility regularly stretches to 30–40 m, the variety of tropical fish is extraordinary, and the coral reef formations and cave systems are remarkably diverse. The Kerama Islands span three island groups, encompassing well over 100 dive sites in total.
As for dive sites on the Okinawa main island, the usual suspects are the Blue Cave, Manza, Zanpa, Itoman in the south, and Hedo in the north. Off Kouri Island in central Okinawa, there is also "Emmons," a wreck site at 45 m featuring an American warship. In truth, there are a great many places on the main island just waiting to be explored by divers — yet very little information is available in Chinese online. So I decided to share my diving journey, little by little.
This time, I was genuinely hesitant to share this hidden gem. Let me start with my dive log from three dives I did at the end of March: maximum depth 59 m, average depth 25 m. Numbers like that tend to make people think you've lost your mind. I thought long and hard about it, but there was still a voice inside me hoping to share this diving experience in Chinese. Whether or not you get to dive here one day is really down to each person's own fate and circumstances.
This dive site was discovered by a legend of the diving community. "Triangle" immediately conjures images of a mysterious triangle — and yes, it really is an utterly mysterious dive site.
2 January 2018 — Great White Shark Sighting at Triangle!
A spectacular creature appeared at this site — a 5 m great white shark — and that is what first brought Triangle to fame. I asked the dive guide who witnessed the great white that day, Mr. Okumura, who also happens to be the owner of「ドリスタ」, the dive shop I use. I asked him whether the great white shark was terrifying. He told me that the presence of a great white simply could not be resisted. Below is the footage captured at the time:
Mr. Okumura is a dive guide with a genuine passion for sharks. He regularly takes his guests abroad in pursuit of shark encounters. In Okinawa, his dive shop specialises in drift diving itineraries, so most of his clients are seasoned regulars. Honestly, I was quite nervous the first time I dived this site. It was here, in late November 2019, that I broke my personal depth record at 53.4 m.

Frequently Asked Questions
How is a BlueTrend dive trip different from an unknown, no-name dive group?
Choosing us means full peace-of-mind protection and a smooth experience from start to finish. Every trip we run holds to three things.
First, full legal protection and a professional dive leader: we strictly follow Taiwan's travel regulations and provide complete travel-agency liability insurance, travel insurance, trip-inconvenience insurance and dive insurance. Every group is accompanied by a certified, foreign-language dive leader who joins you on both the dives and the land itinerary, liaising seamlessly with local dive shops and operators on your behalf to keep things running smoothly — the person our travellers trust most.
Second, fully licensed with secure payments: every payment goes into a licensed travel agency's account, with multiple safe payment channels (bank transfer, credit card and more) and a legal collect-and-remit receipt, so every transaction is open, transparent and protected, avoiding the fraud and dispute risks of transferring money privately to an individual.
Third, hand-picked quality we vet in person: every trip, dive site and partner shop is scouted on the ground by our own team, from the guides' professionalism and safety standards to the food, lodging, environment and service details on land, all vetted by us so you don't get caught out.
I want to sign up for a dive trip. Are there certification-level or logged-dive requirements?
Each dive site is different, so the entry bar varies. 'Bali Tulamben', for instance, is relatively beginner-friendly. 'Malapascua in the Philippines' is also beginner-friendly, but since thresher sharks tend to cruise between 20 and 30 metres, we recommend AOW certification with 20+ logged dives to enjoy this trip comfortably. For 'the Maldives' or 'Palau', we suggest AOW with 50+ logged dives for a more relaxed experience. If you're not sure whether your experience fits the trip you want, message us and our dive editors will assess it and help you find the trip you'll feel safest on.
Can I join if I'm signing up alone? How are rooms arranged?
Plenty of our travellers sign up solo! For rooms and beds, we prioritise pairing you with a same-gender traveller, and if you'd rather have your own space you can pay the difference to upgrade to a single room. For the diving, our professional leader will pair you with a suitable buddy, and with the happy vibe on our trips you'll quickly make a great group of dive friends. Many people sign up alone, make new friends, and end up organising the next trip together!
Does the trip fee include dive insurance, gear rental, taxes and instructor tips?
It depends on the trip, the destination's regulations and the local operators. Every BlueTrend dive trip has a detailed web page with a clear 'included / not included' list, transparent and with no hidden charges. All payments are collected by a licensed travel agency, with a standard-form contract for your protection.
I'm a new diver / haven't dived in a long time — will I fall behind the group?
Before you complete your booking, our team assesses a suitable trip based on your certification level and experience. Before departure, we strongly recommend taking time to refresh in Taiwan with an instructor, or a fun dive to get your feel back. On the trip itself, our professional dive leader groups and pairs everyone by experience, keeps a close eye underwater on travellers who need extra care, and steps in to help right away.
Will the photos and videos taken during the trip be shared with us?
During the dives, 'safety' is always the leader's top priority, so whenever it's suitable and safe the leader will capture great shots and record the best moments. During or after the trip, we compile a cloud album for all travellers to download, so you go home loaded with memories!
Besides your scheduled trips, can you arrange a private group charter or independent travel for me and my friends?
Absolutely! Besides group trips, we also arrange private group charters and independent travel. We can communicate, enquire and coordinate services with local operators based on your needs, saving you time and effort and taking the language barrier off your plate, to tailor the smoothest, most reassuring dive trip just for you. Contact our LINE support and our editors will arrange it for you!
