In general, do Japanese people dislike Americans or British more?

Question:

I'm just wondering.
And, of course, I am in NO WAY suggesting all Japanese peeople hate Western people/are racist/whatever.
I am genuinely just wondering.

Answer:

Definitely, the Japanese feel closer to British.
British and the Japanese share the island-nation mentality which is characterized as polite, reserved and sensitive to the feeling of others. Both nations have long years of history, and their Royal families have very friendly relations for many years. The Japanese have no reason to dislike British.

On the other hand, Americans (especially those in Japan) are ignorant, arrogant, impudent, rude and insensitive. Many Japanese are looking down on them.
Aside from the historical factors, the Japanese do have reasons fo dislike Americans living in Japan.
