Reviews: Snorkeling/diving at the Blue Cave in Okinawa, Japan: shore entry (no seasickness) | Non-swimmers welcome
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!★

Reviews: 2 hrs scuba diving + snorkeling at the Blue Cave in Onna, Okinawa | Non-swimmers welcome
Guest User2026-07-17
There was a field to enter a Line or WhatsApp ID when booking, but I didn't receive any separate contact. It felt like it was just for emergency contact. When you arrive at the meeting point, the counter staff immediately confirms your reservation and prepares for snorkeling. The staff were all cheerful and great. There were already plenty of fish, but they scattered some food once, and the fish practically enveloped me! However, since there are only outdoor showers and changing rooms, it wasn't possible to take off all clothes and shower immediately after swimming. You can only rinse with water, dry yourself off, and change clothes.★

Reviews: Okinawa Blue Cave Diving Half-Day Tour: English/Japanese Instructors/Equipment Included/Shore Entry No Seasickness
Guest User2026-03-24
The guide, Yuya san was very professional and helpful. For me who is a first timer as a diver, I learnt a lot from him on how to dive. I will definitely return again to your diving centre for another round :) thanks!★

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.
