We are total beginners at diving and both over 55.  Our instructor today was Mr Nakano. He was wonderful and thoroughly looked after us! 
He was very very patient, kind and explained everything very well. 
Even though we were a bit nervous to begin with, he made us feel very safe and we trusted him completely. We had a great time!
Mr Nakano was very professional and we highly recommend “Daichan” (Company owner) and Mr Nakano and all the other staff. You won’t be disappointed!
