I have been informed by some non-immigrant Japanese people that they find some Japanese immigrants living in, say, Canada or America, to have their own way of thinking (so that, "yappari" (of course, no surprise!), those people prefer being immigrants in another culture).

So sometimes I ask the question, like it's great in Japan, why do you want to be here? The reasons are various, among them things like, "I like just addressing people by their first name", or "there are people from many different countries and cultures in Canada; people are not 'the same'".

Once on the train (in Canada) I overheard some snippet of conversation among some girls about some planned event, "... minna Nihonjin dakara ikitakunai" ("I don't want to go, because everyone there will be Japanese").
