Japanese women played a massive part in the history of Japanese-American history. They were sent over as wives to the brave pioneers going to live in America at ages as young as fourteen. These girls would have children early, many Japanese-American families having up to twenty children. They were in charge of cooking, cleaning, childcare (for more than 10 kids), and often the finances. They almost always never saw their families again, never returning to Japan.
The Japanese did not face the same racial prejudices as other races, though oppressed, it was more lazily than strong. There were segregation laws, though they were rarely ever enforced. Even with school segregation, it was lax. It just didn't make sense to make an entire new school for five students. They were not viewed as equal, however, whites did not, as they did most other races, view them as absolute scum. Until Pearl Harbor, but that's another story.
