Are the japanese the best inventors in the world?

DA.they are the best in the word .they are very smart and workers and are very good in construction of robots.i was there one time and i see how they think.are sure the best engeneer.

Japanese are quite hard working and disciplined , this is the impression I have about them.As far as the best inventors is concerned , I think they have invented or build some remarkable things in electronics and also automobiles as you mentioned the robot, they are quite ahead in the field of robotics also, but I think not in every field of engineering.
