No flaming, please.

I would rather stay away from categorical characterization of particular ethnic groups. I also strongly refuse to subscribe to any bigotry. It will only contribute to destroying, not building, intercultural understanding.

I have had the good fortune to meet many a respectable Korean in Japan as well as in the United States. Many of my friends are ethnic Koreans living in Japan, very nice people working as medical doctors, professors, or other professionals. The most humble and respectable person I met when I lived in the United States was a Chinese classmate, now a professor at the university I received a doctorate from.

Different ethnic groups have different cultural backgrounds. Some from a crime-prone society or a violence-tolerant cultural tradition may indeed cause more trouble than relatively disciplined Japanese people--we have yet to produce definite proof, though, before making any serious accusations.

To maintain a safe Japanese society, we should do absolutely everything we can, certainly improving our law enforcement system and criminal code. Such efforts, however, should not target any ethnic group. We should rather do more to integrate different ethnic members into our society, learning to accept Japanese of non-Japanese ethnicity--Asian Japanese, Caucasian Japanese, African Japanese, and so on. Given the declining birthrate, that's the only way Japan can survive into the next century.
