Tokyo has almost zero public trash cans. Not in the subway stations. Not on the sidewalks. Not in the parks. Yet you can walk five miles through a city of 14 million people and not find a single discarded coffee cup. In New York, Paris, or London, removing trash cans produces a landfill within four hours. In 1995, Tokyo removed its public bins after a domestic terror attack. The city never put them back. Why didn’t the streets drown in filth? Because in this country, a child is taught from age three: "Your trash belongs to you. Take it home in your pocket." They didn’t solve cleanliness by hiring an army of sweepers. They solved it by raising 120 million people who refuse to make their mess someone else's burden.
