Those make me lean towards cultural factors.

> I was cycling in Japan for about 2 weeks, just a few weeks ago. I was also impressed in most places by how clean it was, not only in the cities, but more generally speaking about everywhere.
> At some point though, I was cycling along the coast of Mie then Wakayama prefectures, and although the scenery and roads were clean, I had a glance just behind the ramp walk, and realized that behind the trees, in the bush next to the road were hundreds of garbage bags, litter of all sort, really anything, just lying below. There was such a contrast from what my eyes were seeing until, I was shocked.
> In another town several kilometres after (I forgot which place exactly, must have been while cycling up towards Wakayama city), I passed next to a big commercial area on my right. On my left there was a small patch of forest then the sea and again, that forest contained many many plastic bags, full but neatly tied up, every couple of meters or so, for several hundreds of meters.
> I originally thought the first thrashes I saw along the road in the country side where "mistakes", like things flying off the window or pushed by the wind from another place (although there was a lot of garbage anyway). But when I saw these tied up plastic bags, they weren't there by chance, really people throw these bags away on the forest right here. That made me a bit sad, especially since it broke the original image I got.
> (And I haven't spoke about the beaches and seafront all along that peninsula; I wouldn't walk bare foot there).
However, when the streets were mostly empty, I saw one Japanese man come to an empty crossing, glance around, and cross on red.
Can't generalize much off a single example, but it did make me think peer pressure is probably a factor.
This said, when people are around there are more likely to be sudden cars as well. It's easier to justify jaywalking at midnight than noon.
In LA, there is no jaywalking enforcement, or any petty crime enforcement for that matter. The LAPD is a disproportionately tiny police force that has far bigger fish to fry. People don't jaywalk though because more pedestrians die from drivers here than any other city in the nation.
And police in America wonder why people hate them so much.
So you end up with broke college kids using their student loan money to ultimately pay for trash pickup or other critical city services that were previously paid for by taxation and higher levels of government.
more broadly, when i see/hear this line deployed by westerners in regard to certain east asian countries, I always wonder if such westerners think such statements are generalisable to other nations, or if they have considered whether other specific cultural factors than uniformity are in play and causing/contributing heavily to the supposed higher level of mutual trust.
It's my view that, other factors disregarded, having fewer cultural/ethnic outgroups does not magically result in higher levels of mutual trust in a society. After more than 4 years in Korea I am tired of westerners using Korean society as a shining beacon-like example of cultural/ethnic uniformity in order to air their beefs with immigration in their home countries (and no, that isn't how I interpreted the parent comment; just pursuing a line of thought).
Another interesting thing to consider: the prevalence of general corporate and political malfeasance in Korea and Japan relative to their status as highly developed nations. Certainly no culture-driven concern for the wellbeing of countrymen there.
edit: Ahh just looked at the parent poster's post history and am now happy to issue a big fat Never Mind. At least I got the thought out.
This is a classic scissor statement to use SlateStarCodex lingo.
