Reviews: [Optional boat types] 1-day tour of Tokashiki Island in Okinawa: light meal + optional snorkeling experience
Guest User2026-06-22
Tokashiki Island, just a 40-minute high-speed ferry ride from Naha Port, is definitely a hidden gem for a day trip in Okinawa! ✨ A shuttle bus takes you directly to Aharen Beach after disembarking. The "Kerama Blue" water is so clear it's like a transparent sapphire; just a few meters out, you'll encounter colorful corals and schools of fish. If you're lucky, you might even spot a sea turtle slowly brushing past you while snorkeling! The island has no noisy water sports, fine white sand beaches, and an observation deck offering panoramic views of the entire bay. Even the breeze blowing through the coconut palms carries the soft scent of sea salt. The included Okinawan curry rice is warm and comforting, and the relaxed feeling of not having to rush is incredibly soothing. Watching the sunset spread across the sea on the return ferry in the evening, even your worries are gently swept away by the waves.

Reviews: Okinawa Japan Blue Cave diving/snorkeling experience: English & Japanese-speaking coach | shore entry without seasickness

We went snowdiving, and the instructor kindly explained everything. We also added GoPro recording on the spot (highly recommended!!). They show Korean YouTube videos for basic explanations. I was worried because the instructor only spoke English and Japanese, but surprisingly, there were no communication issues. Since it was our first time, they took extra care of us, so we were able to enjoy a safe and fun dive!

Reviews: Half-day snorkeling activity in the Kerama Islands, Okinawa, Japan: Pickup and drop-off at designated points in Naha city
Guest User2026-09-29
Choosing this tour was the best decision I made during my entire Okinawa trip. Compared to island hopping for snorkeling, this tour was cheaper and had a shorter travel time, avoiding the chances of my child getting seasickness and allowing more time to enjoy snorkeling. Our hotel was conveniently located near the pick-up point, and the bus ride to the port took less than 10 minutes. After settling in at the meeting point, we set off together, and in less than 30 minutes, the boat took us to the snorkeling spot. With the instructor's help, we put on our gear and went snorkeling. The only slight fear was at first, but the life jackets kept us afloat. The most exciting part was encountering sea turtles, and they even swam around us! It was so much fun. The instructor even took photos for us, and the three of us were all very happy. My child even said he wanted to do it again when we got back to shore. I look forward to seeing you again on my next trip!

Reviews: Happy ocean experience store - turtle snorkeling experience
Guest User2026-08-23
It was a wonderful experience. The guide used a buoy to pull the five of us snorkeling in the sea. Along the way, we saw corals and many marine creatures, including clownfish, groupers, sharks, and even swam alongside sea turtles. The guide took photos and videos of us and the marine life along the way with a GoPro, and then gave us the digital files. These photos and videos were truly beautiful!
