Reviews: Japan Okinawa Blue Cave diving and snorkeling 2-hour experience [Blue Cave snorkeling/diving/English and Japanese instructors/shore entry, no seasickness]

Guest User2025-09-01

This is my second time visiting this dive shop in Okinawa. Located in Onna Village, it's very convenient if you have a car. I was caught in a typhoon in the winter and couldn't get to the Blue Cave, but I was able to go this summer! Both times, the instructors were very patient and professional. The dives lasted about an hour each, and there was a shuttle bus to and from the dive shop.

Me and my sister booked a day adventure which included Canoeing in the Mangroves and snorkelling at The Blue Cave. Our guides were Makoto and Aoe they were both amazing, very friendly and made our experience very memorable. They were easy talk too, and created a very welcoming and inclusive atmosphere to all groups of people. Thank you for helping me and my sister make beautiful memories that we will treasure forever!

The experience was fantastic! Our coach, KAK, was handsome, provided excellent service, and seamlessly switched between Chinese, English, and American languages, which made us feel very safe! Highly recommended!!!
