A Visit to Okinawa Churaumi Aquarium in Japan


Widely celebrated as Japan's best aquarium, the Okinawa Churaumi Aquarium (美ら海水族館) is an absolute must-visit for anyone exploring Okinawa Honto, especially if you venture up to the northern part of the island! Located within the vast Ocean Expo Park (built on the former grounds of the 1975 International Ocean Expo), it promises a truly incredible journey through the diverse marine life of the surrounding waters. Once holding the title of the largest aquarium in the world until it was surpassed in 2005, Churaumi still retains a sense of grandeur and scale that is genuinely impressive from the moment you approach the building.

Geometric Cathedral of Concrete and Glass
Subject Rating: 8/10

Welcome to the concrete jungle's idea of a greenhouse, or perhaps a highly secure, incredibly stylish parking garage roof. The subject here is undeniably the jaw-dropping architectural structure, a repeating V-shaped pattern of concrete beams and glass panels that stretches into the distance, drawing your eye upwards. It's a perspective photographer's dream, or maybe a nightmare depending on how long you stood there craning your neck. The structure creates a hypnotic rhythm, a sort of concrete and glass wave cresting overhead. There's a definite mood of modern, perhaps brutalist, architecture meeting the openness of the sky. It feels grand and a little overwhelming, like being inside a colossal, inverted geometric funnel designed by M.C. Escher after a good cup of coffee.

From a photography standpoint, the composition is the star of the show. The symmetry is strong, with the structure perfectly framed, creating powerful leading lines that pull you into the shot and towards that little peek of blue sky at the end. The lighting is direct and high, casting sharp, graphic shadows that emphasize the depth and texture of the concrete beams – perfect for highlighting the structure, though maybe a bit harsh for anything else. The limited color palette, dominated by the cool grays of the concrete and the vibrant blue of the sky, simplifies the image and enhances the focus on form and line. It's a classic example of using perspective and repetition to create a dynamic abstract architectural shot. Just try not to get a stiff neck admiring it. The watermark in the corner reminds you who captured this masterpiece, hopefully before their neck gave out.


Coastal Paradise with Architectural Interruptions

Subject Rating: 7/10

Alright, let's dive into this snapshot of what appears to be a rather delightful coastal view, slightly interrupted by the realities of modern tourism infrastructure. We've got a vast expanse of deep blue ocean stretching out towards a hazy, distant island topped with a distinctive peak – classic picturesque stuff, easily an 8 or 9 just for the natural beauty. Below, the turquoise shallows hint at coral reefs or just incredibly clear water, making you want to grab a snorkel. The mood is definitely sunny and vacation-like, a bright, cheerful day with scattered clouds adding some interest to the otherwise monotone sky. In the foreground and mid-ground, there's a bustling tourist area with pathways, pools (or reflective water features), and a couple of distinct buildings. People are milling about, enjoying the sun and the view, perhaps trying to figure out where the ice cream stand is. The mix of natural beauty and organized human activity gives the scene a slightly disjointed but ultimately realistic feel for a popular destination.

From a photography standpoint, this shot attempts to capture a wide vista, employing a somewhat elevated perspective that includes the foreground elements while still giving prominence to the dramatic sky and ocean. The composition feels a little busy in the lower half, with the architectural elements and pathways creating multiple leading lines that don't necessarily converge on a single point of interest. The bright sunlight is doing its job, creating a vibrant scene with good color saturation, especially in the blues of the water and sky, though it also results in some slightly harsh shadows in the foreground. The lighting is strong and contrasty, perfect for showcasing those vivid tropical colors. The subject matter is a classic landscape/travel blend, though the inclusion of the foreground development adds a layer of context – showing *how* people interact with this beautiful place. The overall style leans towards a bright, high-key travel photo, perhaps slightly overexposed in parts of the sky but effective in conveying a sense of clear, sunny weather. And of course, no travel photo from Preston Lau would be complete without a tastefully applied watermark, just in case anyone was thinking of stealing this view (or at least the digital representation of it).


The aquarium is cleverly designed, spread out over three floors, with visitors entering on the top (third) floor and following a descending path. This layout mimics a journey through different ocean depths, starting shallow and gradually going deeper, adding a narrative flow to your exploration as you eventually exit on the first floor. Right after the entrance on the third floor, you encounter a shallow, open pool where visitors are welcome to gently touch living starfish and various seashells with their own hands. It's a wonderful, tactile introduction to marine life that immediately engages visitors of all ages, offering a fun, interactive moment right at the start.

Coral Critters Convention
Subject Rating: 8/10

Welcome to the world's most exclusive gathering, perched precariously on a bleached coral reef – it's the Tiny Crustacean Convention! Our main speaker, a rather distinguished-looking fellow right in the foreground, appears deep in thought, perhaps contemplating the philosophical implications of living on textured limestone. Surrounding him are his equally translucent colleagues, some in sharp focus, others drifting into the ethereal blur of the background. This shot perfectly captures the miniature drama unfolding on the seafloor (or perhaps a well-maintained tank), highlighting the intricate details of these fascinating, almost alien-looking, creatures. The macro perspective draws us in, revealing the segmented bodies, delicate antennae, and surprisingly large eyes of these little wonders as they cling to their porous home.

From a photographer's standpoint, this is a solid macro effort. The composition places the primary subject nicely, slightly off-center, allowing the eye to explore the surrounding texture of the coral, which acts as a compelling, repeating pattern backdrop. The shallow depth of field is employed effectively, ensuring the main subject is tack sharp while creating a dreamy bokeh from the other critters and the distant blue background. The lighting, while somewhat direct, does a good job of illuminating the translucence of the subjects and highlighting the intricate details of the coral's structure. The strong blue of the background provides excellent color separation and makes the creamy white of the coral pop. While slightly more dramatic lighting could add punch, the current setup is clean and showcases the subjects clearly. It's a successful capture of a hidden world, proving that even the smallest subjects can make for a captivating photograph.


Touch Tank Tango
Subject: 7/10

Okay, dive into the bustling world of the aquarium touch tank! Here we see a crowd, a veritable throng of curious hands and faces, leaning over a shallow pool. At the forefront, a boy in a bright blue shirt with snazzy blue and white striped shorts is intently focused, reaching out to touch a rock (or perhaps a cleverly disguised, unmoving starfish) in the clear, shallow water. All around, parents guide eager children, pointing out the wonders beneath the surface – the slow-moving starfish, the sandy bottom, maybe a brave little fish darting by. Various objects like rocks and multiple starfish dot the sandy substrate. The background reveals the dark expanse of the aquarium hall, illuminated by vibrant blue display screens showcasing marine scenes, with more people gathered further down the tank. The mood is one of lively exploration and slightly controlled chaos, the air thick with the scent of chlorine and childlike wonder. It's a classic aquarium moment, captured in all its slightly damp glory.

From a photographic perspective, this shot tackles the eternal challenge of low-light indoor spaces packed with unpredictable humans. The composition uses the curve of the tank and the foreground rocks to lead the eye into the action, placing the boy in blue as a strong, albeit slightly cut-off, anchor. Lighting is a mix of ambient and overhead spots, creating some challenging reflections on the water's surface and harsh highlights, though it does help illuminate the subjects' faces and the marine life. The color palette is dominated by blues and muted tones, reflecting the aquatic theme, punctuated by the vibrant blue of the background screens. Capturing sharp focus on so many moving elements is tricky, but the photographer has managed to freeze the main action reasonably well. The watermark of "Preston Lau PHOTOGRAPHY" adds a professional touch to this lively slice of public life, demonstrating a keen eye for capturing the energy and fascination of the touch tank experience, even amidst the throng.


Touch Tank Treasure Hunter

Subject Rating: 9/10

This image captures a delightful moment of childhood curiosity at an aquarium touch tank. Our star subject, sporting a very stylish fedora and a practical backpack (clearly ready for adventure *and* snacks), is leaning intently into the shallow exhibit pool. His hand is submerged, gently reaching towards a starfish, his face lit up with a mix of wonder and concentration as he engages with the fascinating marine life below. The watery environment, complete with sandy bottom, scattered rocks, and other starfish (some looking distinctly unbothered, others perhaps plotting their escape), fills the majority of the frame, creating a rich backdrop for the interaction. Other visitors, including what looks like a sibling or friend, are blurred in the background, highlighting the educational and public nature of the scene. The mood is one of discovery and excitement, a perfect representation of a fun day out.

From a photographic perspective, the low angle places us right in the action alongside the young explorer, making the viewer feel like they're leaning over the tank too. The composition uses the diagonal line of the boy's arm and the edge of the tank to draw the eye towards his hand and the starfish. Lighting appears to be overhead, causing bright reflections on the water surface which add sparkle but also partially obscure the bottom in places – a common challenge with aquarium tanks! The colors are natural and appealing, with the pop of blue from the backpack adding a vibrant touch against the earthy tones of the sand and rocks. While the watermark in the corner asserts the photographer's claim, it's tastefully placed enough not to completely steal focus from the main subject's engaging expression and his important mission of making friends with a starfish. It's a charming snapshot that successfully conveys the joy of exploring the underwater world.


Next, you're greeted by a truly stunning tank featuring what's celebrated as the world's first large-scale exhibit of living coral. Seeing the vibrant colors and intricate, complex shapes of the live coral formations, teeming with countless smaller, brightly colored fish darting in and out of the branches, is like looking into a thriving, miniature underwater garden – a beautiful and delicate ecosystem brought to life before your eyes.

Fishy Business

Subject Rating: 8/10

Ah, the classic aquarium scene! Here we have a group of intrepid explorers, mainly pint-sized, gazing into the boundless blue abyss filled with finned wonders. Three children and a partially seen adult are lined up along a deep blue ledge, captivated by the aquatic spectacle before them. One youngster in the foreground, sporting bright yellow glasses, seems utterly gobsmacked by a passing creature, mouth slightly ajar in wonder. Next to him, a girl in a white t-shirt and a purple visor is intently following something with her eyes, holding a circular fan adorned with pictures – perhaps attempting to identify a species before it makes a speedy escape. Furthest back, a slightly older boy leans forward, using a similar fan not for air circulation, but as a pointer to direct the group's attention, while simultaneously juggling a smartphone, likely documenting the moment or maybe just checking his notifications (the modern-day equivalent of a field guide, after all). Behind them, an adult with a backpack adds to the impression of a family outing or school trip, navigating the wonders of the deep without getting wet. The mood is one of fascinated discovery, mixed with the slight chaos inherent in group excursions.

From a photographic standpoint, this image perfectly captures the challenge of shooting against a massively bright background. The vibrant light from the aquarium tank, while showcasing the marine life beautifully in the distance (check out that school of yellow fish looking like tiny suns!), plays havoc with the exposure on the foreground subjects, leaving their faces a touch shadowed – a common battle in the aquarium environment. Compositionally, the blue ledge provides a strong diagonal line leading the eye into the tank, and positioning the subjects along it works well, although the crop feels a tad tight, losing some context on the right. The color palette is dominated by the cool blues and greens of the tank, punctuated by the warm skin tones and splashes of brighter clothing and objects like the fans and yellow glasses. It's a documentary style, capturing a genuine moment of engagement, complete with the photobombing watermark from Preston Lau Photography, just in case you forgot who was behind the lens of this underwater adventure snapshot. It serves as a humorous reminder that even amidst captivating fish, the photographer's presence is undeniable.


The Star of the Show: The Kuroshio Tank

The undoubted highlight, the centerpiece that inspires gasps of awe from everyone who sees it, is the massive, awe-inspiring Kuroshio Tank. Taking its name from the warm Kuroshio current which plays such a vital role in the variety and richness of Okinawa's marine life, this tank is one of the largest in the world – a truly immense, panoramic window into a simulated open ocean environment.

Deep Blue Traffic
Rating: 8/10

Welcome to the underwater rush hour! This shot perfectly captures the vibrant, bustling chaos of marine life on the move. We see a massive school of iridescent purple and yellow fish, weaving and swirling like a living current. Gliding serenely through this aquatic frenzy are two elegant stingrays, looking utterly unbothered, as if they have a dedicated express lane. Off to the top right, a larger, darker fish, perhaps the enforcer of this underwater traffic system, cuts through the scene with purpose. The overall mood is incredibly dynamic and full of life, showcasing the sheer abundance and energy of the ocean (or a particularly impressive aquarium tank). It feels like witnessing a synchronized swim routine gone delightfully wild, set against a backdrop of infinite blue.

From a photographic perspective, the photographer has done a great job capturing the movement and the sheer volume of fish. The lighting is particularly effective, highlighting the vibrant colors of the school against the deep blue background, making them really pop. The composition is busy, yes, but intentionally so, portraying the density of the school. It’s a challenging scene to compose with so many moving elements, and managing to keep the rays and the larger fish distinct within the swirl of the school is well executed, giving multiple points of interest. While the focus is sharp on the main subjects, capturing the motion blur on some of the smaller fish adds to the sense of speed and activity. The deep blue background provides a clean stage for the drama unfolding, although the watermark adds an unnecessary visual element to the bottom right. Overall, a lively and colorful capture of underwater activity that makes you want to jump right in!


Aquarium Majesty

Subject Rating: 10/10

Okay, let's talk about hitting the jackpot at the aquarium! This shot is a masterclass in scale, presenting the jaw-dropping spectacle of a whale shark – arguably the most magnificent subject for an aquarium photo, earning a perfect 10/10 for its sheer 'wow' factor – cruising through the depths alongside a graceful manta ray. Below these gentle giants, a line of silhouetted humans stands in silent admiration, their forms dwarfed by the immense tank and its inhabitants. The scene is one of profound awe and wonder, bathed in that signature, slightly ethereal, deep blue light that only a massive aquarium can provide, creating a mood that feels both calming and incredibly exciting. The water is teeming with schools of smaller fish, adding a dynamic layer of texture and movement to the vast blue background.

From a photographic perspective, the composition uses the whale shark as a powerful diagonal element that guides the eye across the frame. Including the spectators in the foreground is a brilliant move; their size (or lack thereof) instantly conveys the colossal scale of the tank and the marine life within, transforming it from just a picture of fish into a story about human interaction with the natural world, albeit behind glass. The blue lighting, while challenging for capturing sharp detail, creates a cohesive and immersive atmosphere that feels truly underwater. It's a classic example of capturing a sense of place and scale, reminding us that while we may be land-dwellers, there are other, much larger, creatures sharing the planet, and sometimes, we get a chance to glimpse their world, even if it's just through very thick glass. And yes, the photographer's signature is there, cementing their successful capture of this aquatic grandiosity.


Standing before this colossal acrylic panel, spanning meters high and wide, is a breathtaking experience. The sheer scale makes you feel tiny in comparison to the ocean's vastness. The tank is home to a wide variety of species, creating a dynamic ecosystem right before you, but the most striking and utterly majestic inhabitants are undoubtedly the giant whale sharks and the graceful manta rays. Watching the two (or more!) colossal whale sharks glide slowly and peacefully through the water, their massive forms moving with surprising tranquility, alongside multiple large manta rays that look like they are effortlessly "flying" through the depths with their wide wings, is utterly mesmerizing. They share this vast space with schools of fast-swimming tuna, shimmering trevally, and countless other colorful reef fish, creating a constantly moving, captivating spectacle. It's incredibly easy to lose track of time simply standing or sitting (there's ample space along the viewing wall) and watching this incredible underwater ballet unfold, finding new details with every glance.

Giants of the Deep (in Captivity)
Rating: 9/10 (for the majestic whale shark, 10/10 if it swam closer for a selfie)

Here we witness the undisputed king of the aquarium, a magnificent whale shark, gliding serenely through the vast blue expanse, completely dwarfing the other inhabitants. Below, a line of awestruck humans, reduced to mere silhouettes by the sheer scale and backlighting, gaze upwards, cameras and phones raised, trying to capture a slice of this underwater spectacle. Schools of smaller fish zip about, seemingly oblivious to the gentle giant, while graceful stingrays add an ethereal touch, completing this vibrant ecosystem housed behind glass. The mood is one of quiet wonder and shared amazement, a testament to the captivating power of marine life, even when viewed from the dry side of the tank.

From a photographic perspective, the composition effectively uses the whale shark's massive form as the central element, leading the eye across the frame. Placing the silhouetted audience at the bottom provides essential context and a sense of scale, highlighting just how enormous this creature is relative to us land-dwellers. The deep blue color dominates the image, a classic aquarium aesthetic, while the contrast with the whale shark's distinctive spotted pattern adds visual interest. Lighting is typical for this environment – bright from within the tank, creating dynamic highlights on the fish and the whale shark's skin, while simultaneously turning the observers into abstract shapes. It's a well-captured moment that balances the grandeur of the main subject with the human element of observation, though getting a perfectly sharp shot in these low-light, high-movement conditions is always a photographer's challenge.


To enhance the experience, fascinating feeding shows for the large animals are held twice daily directly in the Kuroshio Tank. Watching the whale sharks feed vertically, or seeing the manta rays gracefully scoop up food, is a unique and dramatic sight. Conveniently located just beside the tank is a high-definition movie theater showcasing beautiful footage and educational information about Okinawa's marine life and the Kuroshio current, providing valuable context and a deeper understanding of the living exhibit you're witnessing.

The Sidewalk Explorer

Subject Rating: 8/10

Our intrepid subject, a young boy sporting a dapper straw hat and practical spectacles, embarks on what appears to be a grand journey along a rather ordinary sidewalk grate. Clutching his trusty yellow stick – perhaps a divining rod for buried treasure or simply a handy poking device – he strides with determined focus. His backpack is loaded, prominently featuring a bottle of "Grape Soda," clearly the vital energy source for any serious expedition. The classic Mickey Mouse graphic on his grey tee adds a touch of nostalgic charm to his adventurer's getup, suggesting that even the most epic quests require a bit of cartoon inspiration. The mood is one of innocent adventure and focused purpose, as he navigates the urban-meets-nature landscape of the park edge.

From a photographic perspective, this is a well-captured candid moment. The composition utilizes the rule of thirds, placing the boy off-center and giving him space to move into the frame. The slightly elevated viewpoint provides a good look at the scene, while the grated path adds a strong linear element and foreground interest. Lighting is soft and pleasant, suggesting overcast conditions or diffused light, which creates even illumination without harsh shadows, allowing the vibrant blues and purples of the backpack and bottle to pop against the muted greens and khakis. The focus is sharp on the subject, with the background falling gently out of focus, isolating our young explorer effectively and maintaining the focus squarely on his determined stride. It's a lovely snapshot of childhood curiosity and forward momentum.


Outdoor Wonders: Shows with an Ocean View

In addition to the main aquarium building, be sure to explore the outdoor areas near the waterfront within the broader Ocean Expo Park. Here, several large pools house other fascinating marine animals. You can catch engaging, energetic animal shows featuring intelligent dolphins, often showcasing impressive jumps, flips, and trained behaviors with the beautiful ocean as a natural backdrop. You can also observe large, gentle sea turtles and unique manatees in their spacious habitats. These outdoor pools and the animal shows are a great bonus and can often be viewed free of charge, offering more wonderful opportunities to connect with marine life in the fresh air.

Stadium Spectacles: A Child's-Eye View
Subject Rating: 6/10

This candid shot plops us right into the middle of a bustling stadium crowd, but our focus is immediately drawn to the two young VIPs in the foreground: a girl sporting some seriously cool purple-tinted glasses and a boy with practical green specs and an epic Buzz Lightyear backpack. They're sitting in tiered seating, likely waiting for or watching a show, program booklet in hand for crucial event details (or perhaps just something to doodle on). The mood feels like typical public event anticipation – a bit of waiting, maybe a little excitement, surrounded by the low hum of a crowd. It’s a slice of family life captured amidst a larger communal experience, grounded by the very relatable sight of kids just being kids, armed with their necessary accoutrements like water bottles and trusty sidekick-themed gear.

From a photographic perspective, the composition gives us a close-up, almost intimate perspective on the foreground subjects, contrasting nicely with the vast, blurry sea of humanity stretching into the background. The natural lighting is soft and even under the large curved roof structure, preventing harsh shadows but also resulting in a somewhat flat look. The colors are generally muted, save for the playful purple glasses, the vibrant Buzz backpack, and the cheerful yellow booklet. The style feels like a snapshot, grabbing a moment without overthinking the framing, which results in chopped-off heads and shoulders around the edges – a common symptom of documentary-style shooting in tight spaces. While the foreground kids are compelling subjects, the cluttered background and the rather large watermark detract from the overall impact. Still, it successfully captures a specific moment and atmosphere, even if it sacrifices some visual polish for authenticity.


Leap of Faith (and Engineering)

Rating: 7/10

This dynamic shot captures the exhilarating peak of a dolphin mid-air, showcasing its impressive athleticism against an overcast sky and distant ocean horizon. The main subject, the dolphin, is perfectly suspended in flight, sleek and powerful, momentarily defying gravity above the performance pool. Below, a trainer celebrates the jump with an outstretched arm and a bucket, while another figure is positioned high above in a cherry picker basket, overseeing the spectacle or perhaps the mechanics behind it. The mood is one of excitement and performance, highlighting the trained bond between humans and these magnificent marine mammals, albeit in a somewhat engineered environment.

From a photographic perspective, the composition is dominated by the powerful diagonal line of the crane arm slicing through the frame, which, while perhaps not traditionally aesthetic, adds a unique element of the operational reality of such shows. The lighting is soft and diffused under the cloudy sky, providing even illumination but lacking dramatic shadows or highlights. The timing of the shot is excellent, freezing the dolphin at the apex of its leap. Objects like the pool structure, ladders, buckets, and ropes clutter the foreground and midground, emphasizing the performance setup. The background provides a natural counterpoint with the serene ocean and hillside, contrasting the artificial performance space with the wildness the dolphin represents. It’s a snapshot that tells a story of training, performance, and the unexpected machinery involved in achieving those spectacular moments.


Leap of Faith (and Fish!)

Subject Rating: 8/10

Well, here we have it: the classic dolphin show spectacle! Our subjects, a pair of leaping dolphins, certainly earn high marks for athleticism and sheer airborne grace. One is mid-arc, seemingly challenging gravity, while the other is just launching, creating a impressive splash. The action is clear and captures the energy of the moment. There's a trainer below reaching out with a target stick, guiding the aquatic acrobatics, and another trainer bending over near the edge of the pool, perhaps prepping snacks or cleaning up, adding a slice of backstage reality to the performance. Off to the left, perched precariously high on a crane, is another trainer, possibly the show's conductor or the designated high-five recipient for the really big jumps. The mood is dynamic and lively, centered around the watery stage.

From a photographic standpoint, this shot feels a bit like trying to catch lightning in a bottle while juggling chainsaws. The composition captures the key elements but is somewhat cluttered – the prominent crane and the slightly distracting lower trainer detract from the primary action of the jumping dolphins and their directing trainer. Lighting is soft and diffused thanks to the overcast sky, which is great for avoiding harsh shadows but leaves the scene a little flat in terms of contrast and color pop. The background, a pleasant stretch of ocean and coastline under a cloudy sky, provides a nice context but feels slightly disconnected from the pool action. Capturing multiple moving subjects like this is tricky, and while the moments of the jumps are caught, the overall framing could have perhaps isolated the main action more effectively. It's a solid record of the event, but maybe next time, let's ask the crane operator to step out of frame, unless he's going to join in the jumping.


The Okinawa Churaumi Aquarium truly lives up to its reputation as a world-class marine facility and arguably Japan's best. From the interactive touch pool and stunning coral exhibit to the sheer scale and majesty of the Kuroshio Tank and the fascinating insights into sharks and the deep sea, it offers an unforgettable, immersive journey through Okinawa's rich underwater world. Combining the incredible indoor exhibits with the outdoor animal pools and shows makes for a full and enriching experience that celebrates the amazing biodiversity of the ocean surrounding this beautiful island. It's a place that inspires awe and deepens your appreciation for the wonders beneath the waves.
