This is really the core of it. The rape of Nanking isn't as well-known as the Holocaust. The belief system lying behind each is the same - they are the superior race and all others are "subhuman." Japan had its crew of maniacs, again not as well known. However, during the war, I heard the name "Tojo" often (Prime Minister and many offices before that). We also heard the emperor's name, "Hirohito." I don't think more than a handful of westerners knew that he hadn't made a decision in 3000 years. However, the war ministers carried the final one to him and he made the right one.The atrocities in China and the rest of Southeast Asia just aren't as well known because they happened outside the West, and the Japanese didn't have the leader or underlings like Hitler and his band of maniacs that are so well known and so easy to hate.
Japan has plenty of foreign workers, over 4 million. However, the path to citizenship is notoriously difficult - hundreds of pages, educational and cultural, etc. Finally, you have to give up any prior citizenship - no dual citizenship there, just as here before 1967 and the Afroyim decision...
