Kata is about following ceremonies and etiquette correctly.
It is a form of behavior appropriate to a particular place and time.
You can see kata at work in all aspects of Japanese life.
The exchange of name cards,the pre-bout rituals of sumo,even the mundane act of pouring and receiving a cup of sake-these are all examples of kata.
Kata also influences the way the japanese work.
