Many Internet users have seen Japanese tourists pick up trash from around campsites and rest stops even when they didn’t make the mess themselves. This habit and others added the description of clean to the list. Did you know that Japanese students clean their schools by themselves? No janitors, just students hauling trash bags, sweeping the steps, and wiping down the halls with washcloths for a good 30 minutes each day. Most storefront owners sweep up the sidewalks and streets outside their stores, too. Making it your business to keep communal space clean is a distinctly different mindset from some Western countries. Just think of all the gum-strewn, littered streets of big cities in America.
