Every nation takes pride in its traditions and ways of life. This doesn't necessarily make them xenophobic. Is there a particular experience you're referring to, or are you looking for a broader understanding of cultural differences?
Are you actually saying that the Japanese people have a monopoly on being right?  Or are you making a generalization about the behavior of the Japanese people based on what you know of that group?  Also, you used the word “xenophobic” which has a very specific meaning.
