Traveling on the large cruiser was extremely comfortable, and with very little rocking from the waves, I felt completely at ease. While snorkeling in the Kerama Islands, I was able to fully enjoy the astonishingly clear waters and colorful coral reefs, making for a truly rewarding experience. I also encountered a sea turtle, and I’m very grateful that they gave me a photo of it as a souvenir.

I took this tour during my last visit to Okinawa and was very satisfied with it, so this time I came back to take the large cruiser tour. No matter how many times I visit, I’m always blown away by the crystal-clear waters of the Kerama Islands, and this time I was lucky enough to spot a sea turtle—I was absolutely thrilled.

I was worried the whole time before departure that I might get seasick, but the large cruise ship hardly rocked at all, so I had a very comfortable trip to the Kerama Islands. Snorkeling in the crystal-clear waters was amazing, and I was truly moved to finally see the sea turtles I’d always wanted to see.
