Where have all the trash cans in Japan gone - and how are the streets still clean?

In Japan, there are almost no public trash cans, yet the streets remain clean thanks to a combination of social norms, public education, and targeted urban policy. The phenomenon, which began after the 1995 sarin gas attack, continues due to maintenance costs and encouragement of home waste separation. Many tourists struggle to dispose of trash and express frustration.

In Japan, there are almost no public trash cans, yet the streets remain clean thanks to a combination of social norms, public education, and targeted urban policy. The phenomenon began after the sarin gas attack in March 1995, when members of the Aum Shinrikyo cult sprayed gas in three Tokyo subway stations, killing 14 people and injuring thousands. As a precaution, authorities sealed or removed public trash cans. Three decades later, the cans have still not returned. Reasons include high maintenance costs, disposal of household waste in public bins, and a deliberate policy to encourage people to take their trash home. In Kyoto, the number of bins has been cut by more than half since 2011. The social norm of meiwaku o kakenai – avoiding bothering others – contributes to cleanliness. The habit of not eating while walking also reduces waste outside the home. The many tourists, over 42 million last year, struggle to dispose of trash and express frustration. At train stations, there are transparent monitored bins, and at Shinjuku Station, cleaning robots have been introduced.
