Discover a blue fantasy world in the Kerama Islands, with great views both above and under water

Okinawa Convention & Visitors Bureau


With its warm weather, clear oceans, and lush forests, Okinawa beckons visitors to enjoy outdoors, the safer place to be in age of post COVID-19. Dive into crystalline waters, enjoy SUP or kayaking surrounded by beautiful views, or just leisurely stroll on an empty beach. The possibilities are limitless!




Okinawa is one of the world’s most coral-rich regions. More than 200 of the world’s 800 coral species can be found in the reefs around Okinawa’s islands. The reefs support a rich biodiversity of marine life, and snorkeling is an excellent way to explore this incredible underwater environment.




Part of the Keramashoto National Park, the Kerama Islands are easily accessible by boat from Naha and offer some of the most breathtaking underwater experiences. You can snorkel from the beaches on the three inhabited islands, Aka, Zamami, and Tokashiki, or join a tour to the many uninhabited islands of the archipelago. Tour operators on the main island also offer day-trip snorkel tours to this beautiful marine paradise.




Enjoy beautiful coral, colorful tropical fish, and, if you are lucky, sea turtles in the clear waters. And if you tire of snorkeling, you can find a spot on the sand to relax. Okinawa’s blue ocean and blue sky await you for a unique holiday experience.
