Combine a disposable culture (beverage bottles, bento boxes) with a lack of garbage receptacles is a recipe for disaster, and that is exactly what is happening in Kumamoto, as Kumanichi points out. To be sure, there are bright spots: many companies begin their morning by tidying up their nearby parks, and some areas have mini tori to deter dumpers, but this really shouldn’t be necessary. Where I come from, if you leave litter, others will jump in your face for it. Perhaps that is what is required in Kumamoto. - WIlliam
