Reviews: Okinawa Japan Blue Cave diving/snorkeling experience: English & Japanese-speaking coach | shore entry without seasickness
Guest User2026-08-08
We went snowdiving, and the instructor kindly explained everything. We also added GoPro recording on the spot (highly recommended!!). They show Korean YouTube videos for basic explanations. I was worried because the instructor only spoke English and Japanese, but surprisingly, there were no communication issues. Since it was our first time, they took extra care of us, so we were able to enjoy a safe and fun dive!

Please note that diving is not possible on the day you are flying back! Snorkeling is possible. This information was not mentioned in the notes on this website as of July 2014. The transfer staff were very kind, and the activities were excellent.

Reviews: Half-day tour to Okinawa blue cave with self-assembly (multiple departure time slots) - optional scuba diving/snorkeling from Onna
Guest User2026-10-09
It was unfortunate that we cannot visit Blue Caves again for our 2nd Okinawan trip but they sure made up for it with an equally beautiful deep sea diving session around the area.

Reviews: [Departing from Onna] About 10 minutes to the point! Easy access by boat! Snorkeling & cute fish at the blue cave / experience diving
Guest User2026-08-03
Very fun experience. We are not experienced in snorkeling and the team took good care of us. We felt very well taken care of. Highly recommend for children too. The cave is a little full but worth it.
