Japan’s national curriculum for elementary schools lists, under special activities, the understanding of the role of duty activities such as cleaning, and of the meaning of working.
A guide of Saitama Prefecture describes kyūshoku tōban, school lunch duty. The pupils on duty carry, serve and clear away the lunch. It advises teachers to rotate the tasks, so that pupils try various jobs and learn to work together. As pupils grow older, more of the work should be left to them.
