How were japanese americans were traeted in world war2

Japanese Americans were often treated very badly. They were called "Japs" and often not allowed service in restaurants or stores. People set fires to their homes, and tried to kick them out of the country. A good example of this in action, is a movie called "little boy". The main character's dad goes to fight the war, and his big brother harasses a Japanese man. At first, the boy tags along and harasses the man along with him, but soon realizes that the man is not bad at all. Hope this helps~!
