Sea Turtles in Kerama Islands

One of the most iconic encounters in Kerama is with green and hawksbill sea turtles. These gentle animals are frequently seen resting on coral heads or slowly swimming across sandy areas. When you find a sea turtle, you can get a close view by slowly approaching it. Some individuals may not be bothered by divers at all and may even come closer or swim alongside you.

For many international visitors, seeing a turtle in crystal-clear tropical water becomes the highlight of their Okinawa diving experience.


White Tip Reef Sharks

Another exciting species commonly spotted is the white tip reef shark. These reef-dwelling sharks are often seen resting beneath coral ledges or cruising calmly along reef edges.

Unlike large pelagic sharks, white tip reef sharks are generally relaxed and non-aggressive toward divers. Wild sharks are very cautious by nature, and sharks swimming in open water will usually swim away quickly. If your guide spots a shark, they will let you know right away, so make sure not to miss it.

On the other hand, whitetip reef sharks that are resting in their reef caves are often more relaxed and may allow you to observe them up close without swimming away.


Sea Snakes

Sea snakes are also frequently seen in the Kerama Islands. With their distinctive black-and-white patterns, they glide gracefully through coral gardens or surface briefly to breathe.

Although sea snakes are venomous by nature, they are typically shy and uninterested in divers. In our tours, we emphasize respectful observation without disturbance. When left alone, sea snakes provide a fascinating and safe wildlife encounter that many divers find unforgettable.


Tropical Fish and Macro Life

Kerama’s reefs are filled with schools of tropical fish such as fusiliers, butterflyfish, anthias, and damselfish. Their constant movement adds vibrant color to every dive.

Macro enthusiasts can also discover nudibranchs, shrimps, crabs, and other small reef creatures hidden within coral branches and rocky crevices. The exceptional visibility allows photographers to capture both wide-angle reef scenes and detailed close-up shots.


Underwater Topography: Reefs, Walls & Caves

Kerama diving is not only about marine life.

The islands offer impressive underwater terrain including coral-covered rock formations, reef walls, natural archways, swim-through passages, and small caves shaped by centuries of ocean movement. Sunlight entering through openings creates dramatic light effects, making these sites especially popular for underwater photography.


Are the Caves Suitable for Beginners?

Safety always comes first.

In our tours, dive sites are carefully selected according to sea conditions and diver experience levels. Many swim-through areas are wide, bright, and open-ended, meaning divers can enjoy the terrain without entering technical cave environments.

For beginners and intermediate divers, we focus on shallow reef structures and spacious formations where natural light is always visible. More experienced divers may explore slightly deeper walls and dynamic terrain when conditions allow.

Gentle natural currents often guide divers smoothly along reef contours, allowing exploration of both marine life and geological features without excessive effort.
