If you read through the description, what they talk about is that the culture is built around the idea of the individual being part of something bigger, and that consideration and respect for that something bigger (other people), is core to your own identity.
That's not hard for a lot of cultures, but it's almost impossible for most cultures in the Western hemisphere, and to change it would require a cultural reset that would run against the grain of many things that make those cultures what they are.
If it were possible though - and there are times when certain subcultures had standards of etiquette different to those widely accepted today in the West - it wouldn't need 100% of people to "sign up", just enough to make it ostracising to not conform. And then the outliers would conform.
We do this already: it's OK (albeit illegal), to cycle through a red light where I live, because lots of people do it, but if you were to try and get served ahead of your turn in a pub, you might get into an argument, because nobody does that without expecting a problem.
I feel like half your post is dancing around not saying this.
I'm saying that culture spreads through fear of being ostracized and the cost of not conforming to that culture. This is true in any country. It seems Japan has a "broader" and "firmer" culture that is rooted in respect to others, but it would take some serious effort for a similar culture to take hold in Europe or the US, I think.
A sense of "non conformity" leading to issues is not unique to Japan though, in Europe it is described as a problem with "multiculturalism".
The British (of which I am one), have spent thousands of years stealing the best bits of immigrant culture but seem to have forgotten that (or have been unable to absorb, for whatever reason), for the last ~60 years. That's leading to a rise in far-right sentiment and a growing desire for mono-culturalism. I can see evidence of that in Germany, France and other European nations. I could easily imagine it appearing more in Japan.
Enforcment is a matter of encoding the rules and then applying a carrot and/or stick -- same as any other rule.
It takes humans years to learn how to do this. Entire books are written on the subject. A major medical disorder affecting millions of people includes a persistent difficulty doing this specific thing. Even normal people have to put serious effort into this if they visit a place where societal norms are different from what they're used to.
If it's not complicated, then I'm sure you can write down the rules for some specific situation real quick. Go ahead....
"Put trash in a trashcan and not on the ground"
That wasn't complicated. And took 30seconds. Are there a lot of rules? Of course. Is knowing them all in advance possible? Of course not. Don't confuse that with 'complicated'.
Fine people who litter. Have an ai voice chide people who stand on the wrong side of an escalator. Both simple.

> However, each region in Japan has a different side to stand. In Tokyo, people stand on the left side and in Osaka, people stand on the right side.
I'm surprised to find this sentiment on a site filled with computer programmers. The most important and difficult lesson of computer programming is that simple-sounding rules have a lot of details that we take for granted.
I think this way of thinking, being obtuse on purpose to try to win an internet argument (without a prize, no less), is the more unnecessary thing. What point does that argumentation try to prove other than that a hypothetical version of you, as opposed to most humans who live in large cities, are an inflexible idiot?
Most people are not 100% unaware of the context in which they are engaging. We know to apply escalator rules when we're at an escalator. We know to put things in bins when we have things to put in bins. What we don't know, we can learn through observation, reading the atmosphere, and making at least a minimal effort not to showboat our individualism and, apparently, any obtuse refusal to engage with our context.
(By the way, I don't actually think you are an inflexible idiot.)
There are some less obtuse issues with your universal pronouncement. There are escalators where it's too narrow to pass. There's no need nor expectation to stand to one side on these. The same goes for escalators that are so long that nobody's walking up them to accelerate their progress, or when nobody is around, or when it's so crowded nobody's able to pass anyway. And, at least in the places I'm familiar with, it doesn't apply in places where people aren't going to be in a big hurry. Stand right, pass left applies to subway stations but not malls.
Maybe this all seems obvious. Well, go to a tourist-heavy place with escalators and observe how much of this is learned behavior that takes repeated long-term exposure to understand.
Manners are really complicated. The escalator thing is a relatively simple example compared to something like, say, paying for a meal in a restaurant with a group, and it's already pretty deep when you dig into it.
My experience living in an incredibly multi-cultural immigrant dense area, is overwhelmingly "No". People like their "home" cultures (generally they believe its the best), and they tend to carry some degree of resentment for their new society for not recognizing that. It creates endless friction at the edges (whereas core values tend to be pretty similar globally).
Japan doesn't really deal with this at all, and what immigrant ingress they have is usually fueled by people trying to live a Japanese like life.
Caving on manners to avoid the "struggle", or rather, caving on manners because one benefits from doing so is just a reflection of how much one values the values. This is simply saying that more often than not we can maintain them, it just might not be worth it to us.
