People talk about racism in Europe and America. Well, of course racism is still alive and kickin', but they don't know what racism is until they take a look at Japan. In the west we're at the point where we're taking in lots of immigrants from diverse background, be it educated or uneducated, from various countries and cultures in the world. That isn't the case in Japan. It's already kinda exceptional for an European to live in Japan.
It is ridiculous to expect anyone to go live in Fukushima just to make a point. Hell, it might be technically impossible. For a white foreigner to work in Japan, you have to take an upper class job, that is, something in engineering, education, entertainment.. or else you'll never get any work visa. But the thing is, there probably ain't a lot of those jobs in the evacuated area of Fukushima. So what you are asking him to do might even be impossible. There might be a way if that person is willing to travel long distances from home to the workplace.. who'd do that kind of stupid effort anyway just because some bloke on the internet asked him so ?
The German Embassy didn't either: they knew better by themselves.
