Yes you are right, this is massive over generalization, and I am rather unhappy with my wording, unfortunately I can not edit my comment anymore. In my culture these almost „polemical statements“ are rather accepted and interpreted differently. I found especially english speaking people have a very hard time understanding my intentions. I should have known better.

Obviously there are not 129 million perfectionists, that was particularly misleading.

However I would claim that Japanese are more likely to favor and reward perfectionism than any other culture I experienced. I am only talking about a trend I may have observed.
