Expect safety gear, photo data, and hot showers near the port, plus a ¥1,000 snorkeling-equipment charge.

“This was the coolest thing I’ve done. The staff supplies you with a life vest, water shoes, flippers and goggles. There is one guide leading the way and one guide behind us. The water was very calm and was easy to swim. I’d recommend taking your time while in the ocean. It can get tiring a bit, but feel free to just relax, float and enjoy the time. Around 11 am, we went to kabira bay for lunch which was nice also. Definitely recommend!”
