If this is you, Itoman's sea and Itoman Diving Service are the perfect match!
Here is why...

We are fully committed to ensuring the safety of our guests.

Safety is my top priority. Since Okinawa is a popular destination for beginners and families, I believe that as your guide, I must take a proactive role in ensuring everyone's safety.
That is why I undergo life-saving training at least once a year, and our boat is equipped with essential safety gear like GPS and pure oxygen. Rather than focusing on profit, I keep my groups small so that I can provide personalized attention to every guest. It is only when safety is fully ensured that you can truly enjoy the beauty of nature!

Itoman: Okinawa's Hidden Gem, Right at Our Doorstep.

When people think of diving in Okinawa, popular spots like the Kerama Islands or the Blue Cave in Onna Village often come to mind. However, Itoman is a hidden gem that is just as spectacular. The water is crystal clear, and the area is rich with vibrant marine life and coral reefs.

What truly sets Itoman apart is that it remains uncrowded! We specialize in a relaxed, small-group style, typically guiding 1 to 4 guests at a time (though numbers may increase slightly during peak seasons like Golden Week). You can enjoy massive coral colonies and breathtaking underwater caves without the crowds. Plus, being close to Naha Airport means you can maximize your precious vacation time.

We are dedicated to showing you the best of Itoman. When conditions are right and guests are up for it, we even venture out for adventurous cave dives or drift diving to spot larger marine life and schools of fish. Even in the busiest seasons, we ensure you have a deep and fulfilling experience!

Full Support for Macro Photography! Camera Rentals Available.

With recent improvements in camera performance, underwater photography has become incredibly popular. Whether you're a seasoned macro enthusiast or a beginner looking to take your first close-up shots, we're here to support you! We'll guide you to the best spots for finding those tiny, fascinating creatures.

I’m a macro photography enthusiast myself and shoot with a DSLR—my specialty is finding tiny nudibranchs! We also offer rentals for the Olympus TG-5, a high-performance compact underwater camera. If you're interested, this is the perfect opportunity to give macro photography a try.

We provide tours on our very own diving boat.

Instead of using a shared commercial boat, we guide you on our own private diving boat. Since it’s a private charter for a small group, you'll have plenty of space to relax, and your belongings will be secure.

This is especially reassuring for beginners and families with children, as you don’t have to worry about bothering other guests. Another major benefit is the efficiency—there’s no waiting around, allowing us to reach diving points quickly and maximize your time in the water. We can also return to shore promptly once the session is over!

More than just a guide—we help you create lasting memories.

My job doesn’t end with just guiding you through a dive or snorkel session. I strive to make your trip unforgettable by taking as many photos of you as possible to share later, and teaching children about the fascinating marine life of Okinawa.

We also offer pickups from Naha Airport or nearby hotels in Itoman (depending on availability), and when time permits, I love introducing local sightseeing spots or even grabbing a meal together after diving! Please feel free to ask for travel advice, like "I want to go here!" or "Where's the best local food?"

I want you to fully enjoy not just the ocean, but all of Okinawa, and leave with wonderful memories. And of course, I hope you’ll come back to see me again and again! (haha)
