There is a type of hostility which is very polite and bureaucratic hostility, the kind encoded in immigration laws and policing... but executed politely.

For example, in a dispute with a Japanese person, the police are pretty famous for making foreigners second class citizens. I'm sure they're polite about it though.

Also a lot of casual disparaging remarks at Chinese and Koreans, along the lines of stereotypes in the US about people from Mexico, perhaps because a similar dynamic exists with illegal immigration.
