The truth is that almost everything is done better in Japan than in the United States. That's because the Japanese have a strong work ethic that includes workers taking pride in doing their best. And that is something that is mostly absent in the United States.
For example, visit a McDonalds in Japan and you'll find employees doing their absolute best to do their absolute best work. Ride Japan's Bullet Train and you'll find workers performing at the highest level of excellence with trains that run on time to the second.
So it isn't just Disney that's different. It's the entire culture. Japanese workers always strive to do their best - and when they miss that mark, it's considered an embarassment. They expect high quality from each other because each one of them offers their best quality work.
American workers are often satisfied with doing the minimum that is required of them and not much more. So we have come to expect the minimum. And when an American company manages to offer something that is a mere step above the minimum, Americans are amazed as if something wonderful was accomplished.
(I urge you to visit Japan someday and see the difference for yourself.)
