I have had one for ten years. Plays like a dream and compared to my Gibson I know which one I go for everytime - the Yairi. It has become my workhorse and that is their strong point. My plays whatever style I throw at it and responds beautifully.
My guvnor (God rest his soul) tried to buy mine off me at least thirty times and he had a guitar collection to drawl over ( Gibson L4 & 175, Martins, Hofners etc) and everytime he came to my house he demanded to play my Yairi.....
I don't like the new ones with the funny two piece tailpiece but the older ones (Mine has the K. Yairi signature on the front) are a real beauty. If i had the money I would buy at least another three, including the twelve string model!
Well thats my honest opinion.
