Reviews: 2-hour diving and snorkeling experience at the blue cave in Okinawa city, Japan [blue cave snorkeling/diving/English and Japanese instructors/shore entry to avoid seasickness]
Guest User2026-05-19
Banja is an excellent tour guide. She took care of us during snorkelling. The sea very calm. We rent go pro for photo taken but quality of under water not good. Lots of people inside the cave so we only stayed there a short well.

Reviews: 3-hour diving and snorkeling experience in the Kerama Islands of Okinawa City, Japan [summer-limited snorkeling activity/pickup and drop-off at designated locations in Naha City]
Guest User2026-06-05
The activity was a good experience, with about two hours allotted for snorkeling. There's a shuttle service, making it suitable for tourists who only want to snorkel. Unfortunately, it's a bit far from the seabed; it would be better if you could get closer to the fish.
