Equality?

I heard that in Japan's Self-Defence Forces women are treated equally. That is , there is no prejudice and discrimination against women. For example,Yumi Fujita,who is Airman First Class, is judged by performance, not gender. I think that in Japan there is still prejudice and discrimination in many working places. But the number of prejudice and discrimination are decreasing. This is a good thing. After I graduate Hirosaki University, I will work in the hospital in Japan. Then, I want to work in the workplace where there is no prejudice and discrimination.Well, is there still prejudice and discrimination in working place in America?
