Why do Japanese men rarely have short hair like inch, but they all do?

Because the buzz cut gives people the feeling that it is too masculine, and the way to survive in Japanese society is not to be sharp, not to make public, not to be too personalized.

The inch is too thick. It is not easy to create a harmonious atmosphere in many business and social occasions.

In Japan, violent gangs and underworld people usually leave an inch.

And the chef in the restaurant. For professional needs, inch looks cleaner.
