Okinawa Mugenshou: Blue Cave Snorkeling & Trial Diving | Chinese-Speaking Guides Available

Set Sail by Boat to Okinawa's Mugenshou Sea

Based in Kunigami District on Okinawa's main island, this activity takes you by small boat to prime snorkeling and trial diving spots. The experience lasts 2.5 to 5 hours and holds a rating of 4.9 (176 reviews).

Rather than swimming out from shore, you'll head straight to the best spots by boat. Along the way, feel the sea breeze as you take in views of Okinawa's islands.

In crystal-clear waters teeming with coral reefs, you'll be surrounded by vividly colored tropical fish — and you can enjoy it all hands-free, with equipment fully included. You can check availability and book via this reservation page.

Chinese- and Japanese-Speaking Instructors by Your Side Throughout

Instructors are available in Mandarin Chinese or Japanese and stay with you throughout the experience to ensure your safety. For first-time divers, being able to receive instructions in a language you understand is a huge reassurance.

If sea conditions aren't ideal before departure, instructors may decide to switch to a better location. Safety always comes first in how the tour is run.

As this is a group tour, it's well-suited for families and groups of friends. The briefing you receive here becomes the foundation for what you'll put into practice once you're in the water.

Into the Water: A World of Coral Reefs and Tropical Fish

Once you enter the water, you'll get an up-close look at the tropical fish gathering around the coral reefs. Fish feeding is also included, so schools of fish may swim right past you.

Snorkeling offers views from the surface, while trial diving lets you experience the same sea from underwater — each offering a different perspective. Age requirements are 9–59 for snorkeling and 11–59 for trial diving.

With sunlight streaming through the clear water, the underwater scenery offers one photogenic moment after another. Staff accompanying you will capture these moments as souvenir photos.

Underwater Photos and Hot Showers — All Included in the Price

Every plan includes underwater souvenir photos, hot showers, and hair dryers, with no additional costs on-site. Equipment for both snorkeling and diving is also included in the price.

After getting out of the water, rinse off the salt with a hot shower and dry your hair before heading to your next destination. All you need to bring is a swimsuit, beach towel, and sandals.

For those with nearsightedness over -4.00 diopters, prescription masks can be arranged — just let staff know your prescription and quantity when booking for clearer views on the day.
