Anecdotally, I visited a friend in Hokkaido for a couple weeks and during my time there (as a white non-Japanese speaking person) I was kicked out of two restaurants upon entry for not being Japanese. Racism exists everywhere.
Yes, racism exists. That was not GP‘s point though. The point was that enough kids in Japan are victims of racism that it gets listed as one of the top reasons why so many pupils don‘t want to go to school anymore. I also highly doubt that there are so many non-Japanese kids in local japanese schools that this is a major problem.
