Tourists visiting Japan often find themselves without access to public waste bins, a situation that has become a notable aspect of travel in the country. This scarcity dates back to 1995, when a doomsday cult known as Aum Shinrikyo released sarin gas in Tokyo's subway stations, causing several deaths and injuries. In the aftermath, government officials removed many public bins from subway and train stations as a security measure, a policy that remains in place today. The few bins that remain often use transparent plastic bags to make their contents visible, which can be confusing for visitors unfamiliar with the system. Many tourists express frustration over the lack of bins, with some complaining about the inconvenience. On the r/TokyoTravel subreddit, users have shared experiences of carrying trash in plastic bags or pockets until they can dispose of it at convenience stores like 7/11, Lawson, or FamilyMart. Some locals suggest eating snacks at these stores to avoid carrying trash while walking, which is a practical tip for travelers trying to follow local customs. The issue has sparked discussions on social media, with some Japanese residents offering tips for managing without bins, such as bringing a plastic bag to temporarily hold trash. In Shinjuku Station, one of the busiest train hubs in Tokyo, trials of robotic bins have been introduced to test their effectiveness in managing waste in high-traffic areas. These robotic bins are part of a broader effort to address waste management challenges in urban centers. In addition to the lack of public bins, other common mistakes made by tourists in Japan include being too loud on public transport, carrying large luggage, and eating on public transport, which is considered impolite. These behaviors have been noted as sources of annoyance for locals, highlighting the importance of understanding and respecting local customs when visiting the country.
