In many schools, each han (group of students) takes turns cleaning a designated area every week, such as the classroom and corridor, the gym, the entrance hall and special classrooms. They use brooms, dustpans, hand cleaning mops (zokin), and sometimes handled mops. Each school designates a specific time for cleaning, the most common times being during the lunch break or after school. Cleaning equipment is stored in each classroom. At the end of the term, a thorough cleaning (o-soji 大掃除) is undertaken, including tasks that cannot normally be done such as waxing the floors.
