Noriko-chan serving lunch. Japanese schools do not use cafeterias for school lunches. Instead, the municipality contracts with a lunch provider which in turn delivers the food to each school. There, the students take part in serving lunch to their classmates, and the class eats together in the classroom. Thus, whenever handling food, kindergarten and elementary school children wear aprons, caps, and sometimes gauze face-masks for hygeine. October, 1998.
