I can understand Japanese folks not wanting to go through the hassle, it's just as frustrateing for me when folks ask questions in Spanish or Chinese when I'm at work as well. It isn't because I'm angery with them, it's because I'm supposed to be able to help them when they ask questions, and I can't do that if I don't understand them. This confusion can lead to misunderstandings and the like.

As to some of the other issues, personally I think haveing a primary lanquage helps in the assimulation process of immigrants and therefore every nation should have one. Nor do I think it's the responsability of the host nation to know every blooming lanquage or culture out there. Cultural sensitivity works both ways, I do think guests should be more receptive to correction from people in whom's nation they are visiting.
