They sell things that come in cups, or with napkins. Lots of people cycle/run/walk here instead of driving, seems pretty stupid.
Taking away the bins doesn’t mean you don’t produce rubbish…
Edit: I think there is still a bin IN the cafe, but most people eat/drink outside. Lots of people asking staff where the bins are. Still hypocritical I think though? (And still mildly infuriating to remove well used bins!)
I do have the impression that Japanese people have a much stronger “social responsibility” with public stuff compared to most westerners.
Whilst this is not wrong and shame is a big motivator in Japan, some otherwise bored cops fining literers for a while would probably prevent that situation. On the other hand, I think maintaining some bins (infra to install and hardware + maintenance cleaning and maybe the odd security check) would be cheaper, beeter, and friendlier
