Have you encountered discrimination or prejudices in Japan ?

[Glenski]

I'm not saying Japan hasn't also played foul at times, but really, no one was burning crosses or lynching people in Japan last I checked. I'm not saying everyone's grandfather here did that either, but let's be frank, it happened. We're not talking war crimes here, this is just the day to day.

You didn't happen so see this recent and overt act of racism, did you? (Gaijin Hanzai magazine) http://www.debito.org/index.php/?cat=27 In essence, your burning cross.

Or this story on a foreigner held in prison since November 2006 without speedy trial and so far with practically zero evidence.

Or this story about how a foreigner was denied hospitalization after a scuffle with the police, was turned down in court because one of his witnesses was a foreigner, and who is now crippled.

The Holiday Sports Club chain routinely bars foreigners because (they say) foreigners “cannot read/write their name and address in Japanese.” Oddly enough, they have an English rule book...

Or the signs that were posted near ATMs showing only foreigners robbing people.

Or the numerous signs reading "Japanese Only". http://www.debito.org/roguesgallery.html
What's next? Sit at the back of the bus? Use separate toilets?

The constitution says one thing, and Japan's signature on the anti-discrimination treaty says the same, but we all know there is blatant discrimination here, and Japan seems to be doing little to enforce measures against it.

Kokumin means people of a nation, or its citizens.
Ningen means humans or mankind.

So, the constitution itself is discriminating when you see it referring only to its own citizens, not visitors, long-term residents, and the like.
