Cities and any polity or group of people cannot be created by some abstract rules or enforced. You need it to be composed of individuals who are disposed to act harmoniously with each other and have a culture (which is basically a bunch of jigging to aid harmonious interactions, you cannot create top down the manners you don't want people to violate). Everyone acting in their own self-interest ends up creating a harmonious organization because all of their self-interest corresponds such that their self interest is reflected in the good of the whole.

Just as a feedback system, if there is something wrong in a city or organization if the person who encounters it sees it as contrary to their own self interest and is capable of dealing with it themselves they will.

If this internal principle does not exist you rely on top down surveillance and enforcement which is basically delusional if it works will only be through violent enforcement against the people. Again in terms of a feedback system, if the polity is constructed out of a bunch of individuals who have a self-interest that corresponds with the good of the whole, there is no need to propagate that information to some manager. The persons directly involved with it are capable of dealing with it mindful of it's impact on the good of the whole because it's good for them. If you do not have that you would need a system of management, evaluation, and enforcement which basically demands the disruption in question is something easy to communicate and form policies around. Anything that cannot be just cannot be dealt with and the system falls under it's own weight. That's why technocracy is a delusion that is always doomed to fail, if the individual units in a system are unable to deal with aberrations on their own it requires the whole mass of bureaucracy to evaluate, construct policies, enforce etc. That is only capable of handling anything which is understandable to that kind of system, which is a small fraction of actual disruptions.

I appreciate the efforts of people trying to emulate the positives of Japanese cities mimicking the externals of it and enforcing it on other people is the opposite of any actual organic system and itself prohibits the more dynamic system that is required for an actually stable polity. If someone sees a wallet on the street they have to see it as their own self-interest not to steal it. If people do not see themselves as having a shared self-interest with those around them there is no enforcement or rules or policies that can make that polity stable or harmonious.

Some cities in Europe have town-centers in every neighborhood within walkable distance. This is extremely valuable for a livable city.

Getting to work without car requires good public transport. Again, some European cities very good at this.

Well - the article does not talk about the more recent hostility to gaijin in Japan.

Example (article) from a year ago:

You can find similar articles by other media outlets. Japan has changed - and is changing. I've also noticed this on youtube, e. g. Paolo from Tokyo suddenly praising new restrictive laws. That was a strong indicator that Japan really fundamentally changed here. An old chinese stratagem is to hide the dagger behind the smile: https://www.echineselearning.com/blog/chinese-slang-hide-a-d...

I am not in any way applying that this applies to all japanese as such, of course; but I am more referring here to a trend where things are changing to the worse. Also, cost of living is high and there is an overcrowding problem in many of the cities. Even then I think the only city that would interest me is Tokio.
