Diving Okinawa: My Favorite Place After More Than 50 Dives

After more than 50 dives, Okinawa is my favorite place I've put on a tank.

I've dived in the Bahamas, the U.S. Virgin Islands, the British Virgin Islands, Oahu and Maui in Hawaii, and Cozumel. Every one of those places gave me dives I'd happily repeat. Okinawa was different. I've never enjoyed the whole experience—from the first look into the water to the last slow pass over the reef—more than I did there.

It wasn't one giant animal or one lucky encounter. It was the mix of wildlife and a reef that looked healthy everywhere I turned. There always seemed to be another layer: fish moving above the coral, anemones tucked into the structure, a moray watching from a hole, and a nudibranch small enough to miss if I moved too quickly.

Of all the places I've dived so far, Okinawa is the first one I'd book again.

Why Okinawa Is My Favorite Place to Scuba Dive

I had a very good trip, and I know Okinawa won't look exactly like this every day. Wind, rain, current, recent storms, season, and the captain's site choice can all change a dive within hours.

On my dives, I got everything I care about most:

• A reef that looked busy and alive. I saw broad coral cover, several coral forms, active anemones, and fish using the reef from the bottom to the open water above it.
• Wildlife at every size. Large schools were only part of the show. Some of my favorite subjects were a tiny nudibranch and clownfish disappearing between anemone tentacles.
• Water clear enough to understand the whole landscape. I could see how the reef dropped away and watch fish move through the blue instead of only seeing the few feet in front of me.
• A small underwater group. Many shops shared our boat, but my actual group was just my instructor and me.
• Better photographs than I expected. I also came home with a longer list of Okinawan islands I still want to dive.

Why the Reef Felt Different

The reef didn't feel like scenery behind the wildlife. It was the reason the wildlife was there.

The reef looked healthy to me because so much of it seemed busy and alive. I saw long stretches of coral in different shapes and colors, active anemones, schools crossing overhead, predators tucked into holes, and tiny animals living right on the surface.

The Okinawa diving guide puts some numbers behind what I saw: the waters around the islands hold about 200 of the world's roughly 800 coral species. The guide also credits the warm Kuroshio Current with helping the region support so much marine life.

All those ledges, coral branches, anemones, crevices, and open water gave animals places to feed, hide, clean, and hunt. I could look out for a school of fish, then move closer and find an animal no longer than a finger.

Wildlife and Fish I Saw While Diving Okinawa

The wildlife was the best part of the trip. My photographs include several kinds of clownfish, schools of yellowfin goatfish, a pufferfish, a large moray eel, a banded sea krait, a hawkfish, a nudibranch, and a sea star. There were also clouds of smaller fish that changed the shape of the scene as they turned together.

The schools made the reef feel active, but I remember the animals holding still just as clearly. A spotted pufferfish rested beneath an overhang. A large honeycomb-patterned moray watched from inside the reef with only its head exposed. I stopped for both.

The banded sea krait was another reminder to look beyond fish. Sea kraits breathe air and return to the surface, but they hunt around reefs. They're venomous and shouldn't be touched, chased, or blocked from surfacing. I stayed back and let it choose its path.

Clownfish in Okinawa: My Favorite Dive

My favorite dive was the clownfish dive.

I found Nemo.

More accurately, I found the kind of fish most people mean when they say Nemo: an ocellaris clownfish tucked into its anemone. It was the moment I had hoped for when I packed an underwater camera, and the reef gave me much more than one orange fish with white bands.

Okinawa is a great place to look for anemonefish. The Okinawa Churaumi Aquarium's guide to local anemonefish says all six species found in Japanese waters live around Okinawa. I photographed ocellaris, Clark's, pink skunk, and tomato clownfish on this trip.

Watching them was better than grabbing one identification photo and swimming on. A clownfish would move into the open, turn, and vanish back into the tentacles. If I held position instead of following it with the camera, it usually came back. I got the photos without pushing the fish out of its normal pattern.

Different clownfish brought different colors and behavior. Clark's clownfish moved farther from the tentacles. Pink skunk clownfish almost blended into the pale anemone around them. Each new patch became a reason to stop and search instead of swimming past.

The tomato clownfish may have been the easiest to spot because its red-orange body held its color against the green anemone. Even from farther away, the anemones gave me a clue about where to slow down and look.

Fish You May See in Okinawa

Okinawa covers too many islands and habitats for one fish list to fit every dive. A sheltered coral garden, an outer wall, a wreck, a sandy bottom, and a current-heavy channel won't produce the same mix.

Common reef possibilities include:

• Clownfish and other anemonefish
• Damselfish, butterflyfish, angelfish, and wrasses
• Goatfish, snappers, fusiliers, and schooling baitfish
• Groupers, hawkfish, and moray eels
• Pufferfish and boxfish
• Sea turtles, rays, octopuses, and cuttlefish
• Nudibranchs and other small macro subjects
• Sea kraits around suitable reef habitat

I wouldn't build an Okinawa trip only around the biggest possible sighting. A red-and-white reef fish holding still in the open and a hawkfish perched in coral gave me time to study patterns that would've disappeared in a wide reef photograph.

Some animals took a much slower search. The nudibranch below was one of my favorite camera subjects from the trip. It looked painted onto the reef in blue, black, yellow, and white.

Manta Rays Around Okinawa

If mantas are the goal, choose the island carefully. Ishigaki in the Yaeyama Islands is the main place I'd look. Okinawa's guide describes Manta Scramble off Cape Kabira Ishizaki as a cleaning-station dive with a high chance of encounters from April through November. Mantas also visit other sites around Ishigaki, but they're wild animals and sightings aren't guaranteed.

Okinawa Prefecture stretches across a long chain of islands, so a hotel on the main island doesn't put you next door to Ishigaki. If mantas are the main goal, I'd stay on Ishigaki and choose dates with help from local operators.

I came home happy without a manta sighting. The reef carried the trip on its own, and a manta gives me a reason to plan another one.

Whale Season in Okinawa

Humpback whales pass through Okinawa's waters in winter. Okinawa's whale-watching guide puts the main season between January and March. The waters around Zamami and Tokashiki in the Kerama Islands are well known for humpbacks, and tours also leave from ports on the main island, including Naha, Yomitan, and Onna.

If you want to see humpbacks, book a whale-watching boat. Hearing one underwater or seeing one during a dive would be an extraordinary bonus, not something I'd expect an ordinary reef operator to deliver.

If whales are a priority, I'd plan a winter trip with separate diving and whale-watching days. You can still dive with the right exposure protection, but the air and boat ride can feel cold when a northerly wind picks up.

Sharks and Hammerheads Around Okinawa

For hammerheads, the name to know is Yonaguni. Okinawa's Yonaguni diving guide puts the Hammerhead Rock season between about November and early May. It also describes an advanced boat-entry drift dive with swift current at a depth around 35 meters.

That's nothing like an easy coral dive. Before booking Yonaguni, I'd look at my training, recent experience, comfort in current, and the local operator's requirements. A shark photograph isn't enough reason to ignore any of those.

Reef sharks also turn up around other islands, but sightings vary by site and day. I'd treat any shark as a bonus and ask the dive shop what people have seen lately instead of relying on a broad seasonal claim.

Okinawa Diving Visibility and Water Conditions

How Clear the Water Can Get

At Okinawa's clearer sites, you'll often hear estimates of 20 to 40 meters, or about 65 to 130 feet of visibility. Don't count on that range every day across the whole prefecture. Nearshore runoff, plankton, wind, waves, current, and storms can all shorten the view.

The Yaeyama guide lists typical visibility of about 30 meters at Nishihama near Hateruma. The broader Okinawa guide calls the Kerama Islands some of the clearest water in the region. Neither number tells you what the water will do on your dive day.

I think I caught a very good day. The water looked like an aquarium. I could still see fish after they left the immediate reef, and the blue held its color across long distances. Names such as Okinawa blue and Kerama blue made sense once I saw that color for myself.

Visibility also changed how I dived. I could slow down, understand the reef's shape, and then choose where to look closer. In lower visibility I tend to focus on a small circle in front of me. In Okinawa I could see both the landscape and the small life living on it.

Why Okinawa Doesn't Feel Like One Destination

Okinawa isn't one kind of dive trip.

The main island has accessible reefs, walls, and wreck diving. The Kerama Islands are known for clear water and coral. Ishigaki is the manta choice. Miyako is known for caves and underwater terrain. Yonaguni adds current, hammerheads, and the debated underwater monument. I could make several trips to the prefecture without repeating the same kind of diving.

My dives stayed on the reef. I never saw a giant animal, but I never ran out of things to photograph: clownfish, smaller reef life, and clear water that let me take in the whole scene. I was also the only diver with my instructor, so I never felt rushed. I had time to settle my breathing, hold my position, and wait for a fish to come back without another diver moving into the same space.

My Cape Manza Dive Log

These are the numbers from my three Cape Manza dives, with feet and Fahrenheit in parentheses.

Equipment I Used

• Backplate-and-wing BCD
• 2 kg steel backplate (4.4 lb)
• 3 kg of additional weight (6.6 lb)
• 3 mm full-length wetsuit (0.12 in)

The plate and added weight totaled 5 kg (11.0 lb), but those numbers only describe my setup. Don't copy them as a weighting recommendation. The right amount changes with the cylinder, exposure suit, water type, equipment, and diver, and it needs a proper buoyancy check.

My TG-7 Underwater Camera Setup for Okinawa

Every underwater photograph on this page came from my OM System Tough TG-7. That includes the wide reef, schools of fish, clownfish, moray, sea krait, and tiny nudibranch.

The setup stayed compact, with physical controls, dedicated underwater modes, and a microscope mode that worked well for close subjects. I usually used an underwater mode for reef scenes and switched to microscope mode when the subject filled only a fraction of the frame.

For scuba, I built the camera into this setup:

• OM System Tough TG-7 — the camera used for every underwater image here
• OM System PT-059 Underwater Housing — the underwater housing I used for its 45-meter depth rating and access to the controls
• DIVEVOLK Single Handle Tray — a compact grip and mounting base
• MINIFOCUS Triple-Hole Ball Clamps — the connection that let me position the light
• OrcaTorch D710V MK2 — a wide video light for restoring color close to the subject
• SanDisk 256GB Extreme PRO SDXC UHS-II V60 — enough storage for RAW photos and 4K clips
• JJC Floating Wrist Strap — useful with the bare camera, but not rated to float the full housing-and-light rig

The camera was the base of the rig, but the light and my distance from the subject had a major effect on color. Water absorbs warm colors quickly, so getting close usually helped more than zooming from farther away. Moving the light a little off the lens axis also kept illuminated particles from filling the frame.

I cover image quality, macro modes, 4K limits, housing, tray, light, memory card, starting settings, and saltwater care in my full OM System Tough TG-7 review and underwater setup guide.

Planning a Scuba Diving Trip to Okinawa

My Shared Dive-Boat Experience

One of the stranger parts of my trip happened above the water.

My dive shop didn't take me out on its own dedicated boat. It paid for space on a local fishing boat shared by more than seven dive shops. The deck was busy with separate instructors, customers, tanks, and equipment, all following the same boat schedule.

The upside appeared as soon as we entered the water: my group was only my instructor and me.

The boat was crowded; the dive wasn't. That one-to-one setup made the day much more enjoyable. I could ask questions without holding up a large group, and my instructor could point out wildlife at the pace we were actually moving.

The tradeoff was less control over the boat itself. With several businesses sharing one vessel, each small group had to fit the departure time, site choice, surface interval, and return around a larger plan. Gear organization mattered too. A compact camera rig was easier to manage than a wide tray with several arms would've been.

That was my boat arrangement, not a rule for every Okinawa shop. Before booking, I'd ask:

• Does the shop own its boat or buy seats on a shared charter?
• What is the maximum number of divers per guide?
• How many total people are expected on the boat?
• Are rental gear, tanks, weights, and lunch included?
• Is the day built around two dives or three?
• How far is the harbor from the shop or hotel?
• What happens if weather changes the planned sites?

The answer I care about most is divers per guide. A large boat can still lead to a quiet dive when the underwater groups stay small.

The Best Time to Dive Okinawa

No single month is best for every Okinawa dive goal.

The tourism guide lists average water temperatures around 21.5–28.6°C (about 71–83°F) and says you can dive year-round with the right gear. Each season changes the plan:

• Spring: Water begins warming, and the April-to-November manta window around Ishigaki opens. May and June overlap with the rainy season.
• Summer: Warm water and long days make reef diving inviting. It's also a busy travel period, and strong sun makes surface protection important.
• Late summer through fall: Conditions can be excellent, but typhoons are a real planning risk from August through October. A storm can cancel boats even when the weather looks better from shore.
• Winter: Water is cooler and boat rides can be windy, but humpbacks arrive and Yonaguni's hammerhead season is underway.

I had great visibility, but I wouldn't book a flight expecting every day to look like my photos. If diving is the main reason for going, I'd leave at least one weather-buffer day. I also wouldn't put a must-do dive on the last possible day before departure; weather and proper no-fly intervals both need room in the schedule.

How I Would Plan My Next Okinawa Dive Trip

I already know I want to return. Next time, I'd pick one part of the prefecture and one main goal instead of treating “Okinawa” as a single destination.

Reef-Focused Diving

I'd return to the clear coral sites that made this trip so good and book several days, not one isolated boat. The same area can bring a different set of animals in different light and tide, and multiple days protect the trip from one weather cancellation.

Manta Ray Diving

I'd stay on Ishigaki and work with a local operator that regularly visits the manta cleaning stations. I'd still expect a normal reef dive if the mantas didn't arrive. Wild animals don't owe a boat a sighting.

Winter Humpback Whales

I'd travel in winter and book a separate whale-watching tour instead of asking a scuba trip to do two different jobs. Diving and whale watching can fit the same trip without making a chance underwater encounter the measure of success.

Yonaguni Hammerhead Diving

I'd treat Yonaguni as a separate advanced-diving trip. Its current, depth, and blue-water drift style call for more preparation than the easy reef dives I described here.

Wherever I went, I'd keep the same ground rules: confirm the guide ratio, ask about the boat arrangement, practice with the camera before entering, keep the rig compact, and leave the reef exactly where I found it. No photograph is worth touching coral, crowding an animal, or losing control of buoyancy.

My Verdict After More Than 50 Dives

Okinawa gave me my favorite diving experience after more than 50 dives. A manta, whale, or shark wasn't what put it first; the reef held my attention for the whole dive.

I found Nemo, then found several of Nemo's neighbors. I watched schools stream through blue water, photographed a moray from outside its shelter, kept my distance from a sea krait, and slowed down enough to notice a nudibranch against the reef. The water clarity let me enjoy the landscape while the wildlife rewarded every closer look.

Okinawa earns a 10/10 from me. Of all the places I've dived so far, it's the one I most want to see again.
