tons of 7-11 on the west coast...
I don't know about Europe, but I believe that the Japanese folks that ask the "stupid" questions would not do so if it was in their native language...ok...most of the people...and even the bright intelligent ones I believe have this severe "complex" when it comes to dealing with the "gaijin" that even though in more calm rational times they would not behave that way, when it comes to dealing with foreigners, their "complex" that is typified by a past NOVA commercial of having all of the nihonjin turning into "rocks" when confronted by a foreigner explains the rather irrational nature of the questions.
The reason I say this, and for those that know me here know that I know nothing so probably shouldn't stick my neck out with this explanation, but from my own personal observations, I often wondered why the Japanese ask these dumb-*** questions when it comes to foreigners...whether it was based on prejudice, racism, or just out and out irrational "gaijin complex" that makes one person behave ultra extroverted around foreigners and another to clam up tighter than the shellfish...
The advantage (or disadvantage) I had to learn some of this is that because all of my ancestors came from the land of the rising Engrish, the one thing they always told me when they found out I was amelikajin was that I look like a Japanese, so they weren't intimidated by my appearance. This, of course, had the negative side-effect that many times people thought I was a complete idiot when I didn't understand what one of them was saying to me. But one learns to live with one's handicaps...

In the ideal world, I agree that the Japanese would do better if they stopped looking upon foreigners with awe or shock-horror...but since that ain't gonna happen any time soon, it's probably best to just "accept" the fact that in the long run, you aren't going to change their ideas or views of foreigners...the only thing you can change is how they perceive you...and also how you perceive them...and also how you perceive how they perceive you...
Since you're practically a native speaker there, it goes without saying that you know the history and the current trends probably better than I would, (alternatively, if you are not practically a native speaker, then get into practice so you can be!

),but the one thing I did learn in Japan was that nobody forced us to go there or live there or put up with the nightmares or joys that one can find there, so if the complaints become too unbearable, then it naturally goes that nobody is forcing anybody to stay there, either...but it is obvious that you find the stay there far outweighs the negatives, so that is why you stay...and that should be reason enough to also just learn to accept things for what they are, and if you have the ability to change one or two people to get out of their gaijin complex, then that should be the goal, rather than stressing out on why the people ask the stupid questions....
It is very easy to focus on the negative aspects of living in Japan...but the challenge is how are you going to break that cycle of stupid question asking or their clamming up when they encounter you? Or your own frustrations with their constantly saying, "Gee you use that chopstick very well..."
Be proactive....the next time somebody says that to you, find an opportunity when they are using a spoon or a knife and fork at an elegant spaghetti restaurant, and smile, kindly and say, "Gee, Sato-san (or whomever it happens to be) you really use that fork very well..."
It's really all about perception...and how one perceives others perceiving us...and how well you take advantage of that perception to better your own situation...or not...

This has been a generalized statement not directed at any one person but to everybody or nobody as you wish to perceive it...
