i agree the point that except the boss all staffs are lack of knowledge in toys and the attitude are bad especially the fat guy with glasses. He rarely has answer to your question and very inch. Just guess, maybe he is one of the boss's relative otherwise he should be fired as early as possible.....
Moreover, as his business is now big enough, the boss could hedge the FX risk by using forward contract or other derivatives. I think the continuing appreciation on JPY is just a excuse to keep his profit margin at a constant rate......
