Entrance Good morning, Katsujo In Japan, people take off their shoes before entering a house, At school, as at home, students must change into indoor footwear at the entrance, and are scolded by teachers if they don't differentiate between indoor and outdoor shoes.
Students go to their homeroom and put their bags into lockers at the back of the room.
Unlike in many western schools, the students remain in their homeroom , and the different subject teachers come to them in turn. Students change classroom only for Art, Music, P.E , Industrial Art and Home Economics. We can say that at school, the homerooms are their houses and the homeroom teachers are their parents.
