The beautiful emerald-green waters of Kabira Bay truly cleansed my soul... As I peered into the ocean from the glass-bottom boat and let the gentle waves rock me on my SUP, it felt as though the hustle and bustle of everyday life was slowly melting away… I was also soothed by the mystical atmosphere of the Blue Cave, and I was able to spend a truly peaceful and happy time… It was a wonderful, all-inclusive tour that even included transportation…

Since we have a young child, I was worried about whether we’d be able to enjoy the whole day, but since we traveled by bus, it was a huge relief that we could rest in the cool vehicle. On the glass-bottom boat tour at Kabira Bay, we saw lots of beautiful fish without even having to go underwater, and our child was thrilled. We also had a great time interacting with the squirrel monkeys at Yaima Village. Our whole family had a truly satisfying day.

Everything went smoothly. We were able to efficiently tour the glass-bottom boat and Yaimamura, and since transportation was included, we didn't have to worry about getting around. The arrangements were well-organized, which was a big help. We'll definitely use this service again.

I took a bus tour with my kids to explore Kabira Bay and Yaima Village. The kids’ eyes lit up when they saw the fish in the ocean from the glass-bottom boat, which made me very happy as a parent. At Yaima Village, they got to interact with squirrel monkeys and seemed to have a great time the whole time. Since they could relax on the bus during the trip, it was a truly wonderful itinerary for families with children.

It offers excellent value for the price. I really appreciate how the package combines two distinct experiences: first, observing coral and fish from a glass-bottom boat without getting in the water, and then directly enjoying the crystal-clear waters of Kabira Bay on a SUP. The complimentary photo service is also excellent, and I think it’s a well-designed itinerary that allows you to efficiently enjoy the scenic spots that define Ishigaki Island.
