Not only are there no trash cans in Japan, but there are no paper towels i. The public restrooms. Folks carry their own towels, dry their hands after washing, and carry the used towel with them. In our country, restrooms are painfully littered by "towel droppers" using the provided towels to open the door and simply dropping it on the ground. To my mind, there is a special place in hell for those turds.
