For one reason or another, the Japanese school of story-telling has a pretty prominent streak of this type of low-stakes, downtempo "slice of life" premise like this, that I find very satisfying. The director Hirokazu Koreeda has made many films of this type as well. For a while my wife and I would alternate watching Spanish films by Pedro Almodóvar and Koreeda on movie night, working through both catalogs, which somehow made a lot of sense together.
It’s far from exclusive to Hacker News. In fact, it doesn’t seem to be that prevalent here, as when it’s mentioned it at least tends to be in relevant context. Reddit, Tumblr, Imgur, and plenty of other communities both on and offline have an appreciation for Japanese culture.
> although I've come to realize that it's mostly Americans holding up an example of everything they feel they lack domestically, and in that sense isn't so much about Japan as it is about America
Also not related to America at all. It’s just as common in Europe and western countries in general. Generation probably plays a role. Find anyone who had their mind blown by an anime at a formative age, and you’ll find someone who to this day is likely to have some degree of fascination with Japan.
I'm not so sure. Or, rather, reasons can differ. I'm not into anime at all, but every time I visit Japan (was just there in April, after not having visited since 2017), I am constantly finding little things and thinking "it's a shame we can't have that sort of thing in the US".
I'm generally positive on the concept of government regulation, but the US & US state governments tend to over-regulate so many things, like zoning and alcohol licensing (as mentioned in the article). Culture plays a part too, certainly.
