In American schools, when lunch ends,children throw their trays into plastic bins and walk away.A hired janitor comes in later to sweep up the mess.In Japan, there are no janitors.At 12:15 p.m., the students put on white smocks, hairnets, and masks.They carry heavy pots of soup from the kitchen themselves.They ladle out equal portions for their classmates.Nobody touches their spoon until everyone is served and they say “Itadakimasu” together.Then, at 1:00 p.m., something even more profound happens:O-soji. Cleaning time.Seven-year-old kids get on their hands and knees with white cloths — zokin.They push those cloths down the long wooden hallways,polishing the grain until it shines like glass.They wipe the chalkboards. They clean the toilets.The teachers clean alongside them.Why make children scrub floors?Because when you spend fifteen minutes on your knees scrubbing a floor,you will never, for the rest of your life,drop a piece of trash on it.It teaches a child that no work is below them.No human being is born a master.A high-trust society isn’t born from laws.It’s born on the knees of seven-year-oldstaking pride in a clean floor.
