Households in Tokyo don’t pay to have normal garbage collected. Only large items, like futons, suitcases, etc. Not stuff you’d be throwing away at the conveni.
Sidewalk and subway station trash cans in Tokyo disappeared en masse in 1995. Store trash cans have gradually moved indoors and gotten smaller openings in the intervening decades.
JR train stations now usually have trash cans, with small openings, if you look hard enough.
