The reason why Japan is a poster child of G 20?

G20 is said to be the de-facto world goverment. The reason they love Japan is that she does not defy the G20's demand for Japan. Also she never even question about what G20 tells her. That is to say, a kind of feudalism. In Japan, you can see feudalism every where because Japanese still think the most valuabl thing in life is to obey the order of the superior, such as parents , teachers, and bosses. This character made the corporate Japan stronger than other countries during '60s to '80s. Japanese are not only obedient but also homogeneous. Because they watch and correct each other untill they all look like the same. This practice was promoted by Edo Samurai goverment. People were made like the stone wall of Edo castle in the middle of Tokyo.
This homogeneity is what the future global goverment want for people. They want people do not oppose their will. They want people act like a herd. They want feudalism.
