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]

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.

The activity was fun and I got to meet new people. The staff were responsible, capable, and even helped with photography. Also, the transportation from the hotel to the activity venue and back was very convenient.

The waves and wind were strong, but they were kind and it was fun.
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]

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.
