Japanese values VS American values

In my class I learned about American culture values. I made an essay to compare to Japanese cultural values and American cultural values as a an assignment. I'd like to post it below.

How are your cultural values different from American cultural values?

It is said that three words describe Japanese cultural values; patience, constraint, and endurance. I think they are based on the Japanese tradition called "Shame Culture".
A shame culture is one in which the primary device for gaining control over children and maintaining control over adults is the inculcation of shame and the complementary threat of ostracism.
In a nutshell the key point of "Shame culture" is the fear of rejection. People tend to act in a group(society), and when someone doesn't act in concordance with society,they are ostracized; society pressures him or her, adding to his or her shame. Due to his or her fear of rejection, he or she to return to conformity. For example, people who don't care much about other's pressure are called K.Y(Kuki Yomenai i Japanese). This word usually used in negative way. To survive in this culture, we must get used to it . As a result, we're specialized sense of patience, constraint and endurance.
On the other hand, American culture is called "Guilt Culture" A guilt culture is defined as one that emphasizes punishment and forgiveness as ways of restoring the moral order.
A simple idea of guilty culture is that society builds a standard to judge whether your behavior is ethically good or not, people follow this system. In fact the border is strongly connected with religion(this goes back to the Pilgrims whose puritan values skill influence society.) That's why American cultural values represent initiative, progress and individualism.
Also high rats of immigration have been contributing to American cultural values as well.
The different ways of thinking from those two cultures affect our ideas and behavior.
In fact, some of my friends told me that the style of participation in class bothers them. They hesitate to say something in class, given that they grew up in Japanese culture as I mentioned. But just in my case, I don't feel anything frustrating to me. Intrinsically Japanese cultural values haven't suited for me. As proving, my tutor called me off that I was lacking of a feeling of concordance and I couldn't survive in Japanese society, when I was in Japan.
