Our group was not fluent in Japanese and first time divers, but with Harazaki-san's patience, energy, and enthusiasm, we had a great time diving in one of Yakushima's beaches! 

We started with a lecture where he clearly demonstrated what we needed to know, and we had some practice sessions before we fully went it. He made sure to watch over our group 100% the entire time which was very reassuring. Oh, and he took a LOT of pictures which we really appreciate!
