Discrimination is rampant in Japan, in many forms you'd need a lot longer list for.

Many other less known examples, i.e. until a couple of years back non-Japanese students attending International schools were not allowed to enter Japanese universities, and now they are, EXCEPT Koreans.

Buraku, still exist and still goes on though quietly now.

Japanese companies refusing to pay foreign workers Medical insurance and Pensions even though required by law to pay.

How about plain ignorance? We all speak English didn't you know?

I interviewed a teacher for my school, he was very professional and a good choice, a native English speaker. But in the end rejected by my boss because he was half-Chinese.

I have a list a mile-long.
