Answer:
Ethnocentricity
Explanation:
Ethnocentrism is the concept where one person judges someone else's culture by looking at it through your own cultural perspective.
Here, Jay does not want to show that he is judging the Japanese culture through his own cultural perspective. He does not make distinctions of what is considered wrong in Japan versus what is considered wrong in his country.
Hence, Jay is being mindful of Ethnocentricity.
