actually, as mentioned before, japan got one of the highest suicide rates in the industrialised countries, mostly because of social pressure and unemployment.
So good luck fitting in as a western, and at the same time getting a job at the age of 14 when the hard working japanese people can't even get one. You might already boy a rope before you go there.
I mean, japan must be great to visit on a vacation, as a tourist, but living there would be worse.
