Yes. They see things like "Japanese fans cleaned the stadium before they left" and want to be part of a society like that even if they wouldn't have personally helped clean the stadium. They want to be surrounded by people who do.

That last statement was probably too harsh. I'm sure plenty of the weebs would help clean up if they were surrounded by others who were cleaning up. For me personally there's a lot to like about Japan. Mainly their civil infrastructure. Not just the fast trains but actually having walkable cities where you can reach everything you need on your own two feet. And keeping it affordable relative to other even less densely populated cities. And I hear the excuses about places like San Francisco where they really don't have the land to expand. Welcome to Japan. Your excuses suck. Zone and invest better. But I wouldn't want to live there. They are way too conservative and thus obsessed with hierarchies and keeping people "in their place".
