Nestled in the vibrant heart of Naha, Okinawa, Kaiyo Aventure Tours was born from an unyielding passion for the ocean's mysteries and a deep desire to share its wonders with the world. Our founders, a collective of seasoned PADI professionals and marine enthusiasts, envisioned a dive company that prioritized not just adventure, but also profound respect for the delicate marine ecosystems of the Ryukyu Islands. From our humble beginnings with a single boat and a shared dream, we have grown into a premier dive operator, renowned for our commitment to safety, quality, and unforgettable underwater experiences.

At Kaiyo Aventure Tours, we firmly believe that the magic of diving is best experienced in small, intimate groups, allowing for personalized attention and a deeper connection with the underwater environment. This philosophy ensures that every diver, from the nervous first-timer to the experienced explorer, receives the guidance and support they need to feel confident and fully immerse themselves in the beauty that surrounds them. Our dedication to excellence extends to our equipment, which is meticulously maintained and regularly updated to meet the highest PADI standards, ensuring your comfort and security on every dive.

The backbone of our operation is our incredible team of local and international PADI-certified instructors and divemasters, each bringing a wealth of knowledge, passion, and a friendly Okinawan spirit. They are not just guides; they are storytellers of the sea, eager to share insights about the unique marine life and geological formations that make Okinawa's waters so special. We are deeply rooted in the Okinawan community, respecting local traditions and the profound cultural connection to "Umi" – the sea – which sustains and inspires us.

Our commitment to eco-consciousness goes beyond "leave no trace" diving; we actively participate in local reef clean-up initiatives and promote marine conservation awareness among our guests. We strive to be ambassadors for Okinawa's precious marine heritage, educating divers on responsible practices to help protect these underwater treasures for generations to come. Looking ahead, Kaiyo Aventure Tours aims to continue expanding our conservation efforts and to introduce innovative, sustainable ways for people to connect with the ocean. We dream of fostering a global community of ocean lovers who are as passionate about protecting our seas as they are about exploring them.

Whether you're seeking the thrill of a deep wreck dive, the tranquility of a coral garden, or your very first breath underwater, we are here to make your Okinawan diving dreams a reality. We extend a warm "Mēnso-re" (welcome) to divers from across Japan and around the globe, inviting you to join us and discover the soul-stirring beauty that lies beneath the waves with Kaiyo Aventure Tours.

Tour: Guided Fun Dives (Kerama Islands)

"I've dived in Okinawa several times, but Kaiyo's tour to the Kerama Islands was the best experience so far. The staff were exceptionally kind and professional, and the boat was very comfortable. The clarity of the Kerama waters is always breathtaking. Being in a small group allowed for a much more relaxed and personal dive. I will definitely be booking with Kaiyo Aventure Tours again on my next trip!"

Have questions about diving with us in beautiful Okinawa? We've compiled answers to some of the most common inquiries. If you don't find what you're looking for here, please don't hesitate to reach out to our friendly team – we're always happy to help!

Do I need diving experience for the Discover Scuba Diving program?

Absolutely not! Our PADI Discover Scuba Diving program is specifically designed for complete beginners who have never dived before. You'll receive a comprehensive safety briefing, learn some basic underwater skills in shallow water, and then be under the direct supervision of a certified PADI professional for your entire underwater experience. It's the perfect way to try scuba diving in a safe and fun environment.

What is included in the tour price?

Our tour prices are generally all-inclusive. This typically means all necessary scuba or snorkeling equipment rental (mask, snorkel, fins, BCD, regulator, wetsuit, tanks, weights for divers), boat fees if the tour involves a boat trip, professional PADI guide services, and basic dive insurance. For PADI courses, the price includes all required PADI educational materials (digital or physical) and your certification processing fee upon successful completion. Specific inclusions are always detailed on each tour or course description page, and we're happy to clarify if you have any questions.

What should I bring for a dive or snorkel tour?

We recommend you bring the following items: your swimsuit (it's easiest to wear it under your clothes to the dive shop/boat), a towel, reef-safe sunscreen (to protect Okinawa's delicate corals!), a hat, sunglasses, and a reusable water bottle to stay hydrated. If you are a certified diver, please remember to bring your certification card and your logbook. For PADI courses, bring any pre-study materials that were assigned to you. Most importantly, bring your sense of adventure!

What is your cancellation policy?

We understand that plans can change, so we try to be flexible. Generally, cancellations made more than 48 hours before the scheduled tour time receive a full refund. Cancellations made between 24 to 48 hours prior to the tour may incur a 50% cancellation fee. Cancellations made less than 24 hours before the tour or no-shows are typically non-refundable.

Please confirm the specific cancellation policy applicable to your booking at the time of reservation.

Is diving in Okinawa safe?

Yes, diving in Okinawa is considered very safe when conducted with reputable, PADI-certified dive operators like Kaiyo Aventure Tours. We adhere to strict PADI safety standards, ensure all our equipment is well-maintained and regularly serviced, and our experienced PADI instructors and divemasters prioritize your well-being above all else.

Your safety is our number one priority.

Do you offer instruction in English?

Yes, absolutely! Many of our PADI instructors are fluent in English, and we regularly conduct tours, Discover Scuba Diving programs, and PADI certification courses for English-speaking guests from all over the world. We aim to make your diving experience comfortable and clear, regardless of your native language.
