Funnily enough that’s where I find most of the litter in Japan, like, if you go to any non-main road that goes through a bit of forest, you will see signs threatening fines for littering, with a bunch of trash tossed in that exact area.

I have seen cans, bottles, ACs, TVs, baby car seats, bags, and general household trash. Also found a golf club once that I actually brought home because I thought that it was neat. And this is only along a single stretch of road that is only like 1km long.

So Japan isn’t some miracle society that doesn’t litter, it’s just that they do it someplace that is somewhat out of sight.
