Answer:
Mores
Explanation:
Mores are the behaviors and customs that people have in a particular place and usually, they expect that you adhere to them when you are there and you would probably be judge based on that. According to this, the answer is that Michael's violations of such mores, which concerns routine social conventions, is probably the main reason that he fails to have Norio sign the contract because he didn't follow the custom people have in Japan to establish close personal relationships before talking about business and that affected his image because Michael's behavior was not acceptable for them.
