Most Japanese schools do not employ janitors or custodians. The Japanese education system believes that requiring students to clean the school themselves teaches respect, responsibility, and emphasizes equality
They hire maintenance staff, but no janitors. This is because the students and staff do all of the cleaning themselves. This takes place every day, usually for 10 or 15 minutes, depending on the school, longer before vacations, and sometimes twice a day. (This might happen the day of the school festival, or on graduation day.)
