I'd avoid using Japan as an example for things like this. I won't even mention the whole homogenity thing. It's the culture. Culture is the most important thing. Japanese people, or people who live in Japan, on average more likely give some shit about other people, or the overall society. Shame is also big in Japan, while not a thing at all in most Western, individualist societies. Shame alone can make a Japanese person or someone living Japan think twice about littering. Shame alone makes a Japanese salaryman clean up his own vomit off the street after spewing his guts after a long drinking night. You will never get most Americans to do anything on this level. Hell, they take pride in not giving a fuck about others.
