Oh, well, it seems to vary from school to school then since a friend of mine is a Japanese HS teacher in Miyazaki Prefecture and in his school the students move around between classes ;)<br/><br/>Remember a lot of classes need specialist equipment: PE, art, music, the sciences, cookery, IT, blah blah, so the students must walk around campus a lot anyway.<br/><br/>Also there is this unique ritual in Japanese schools of the indoor footwear which are soft slipons, often white. Just inside the main entrance are rows of small lockers about 1 foot square in which students put their outdoor shoes and put on the indoor slippers. These are worn around campus all day except lunch break when outdoor shoes are worn when students go outside.<br/><br/>Usually between buildings will always be covered walkways so the students use these and keep their indoor shoes on.<br/><br/>Its a ritual thing, a cleanliness thing I assume in the same way that everyone takes off their outdoor shoes in the home, even visitors.<br/><br/>The shoe lockers are famous in anime and manga for people to leave 'confession' letters in for someone they love ;)<br/><br/>Full sized lockers, US high school style, are at the back of the classroom and sports equipment, books and big stuff like musical instruments can be stored here.<br/><br/>I have no idea how the indoor/outdoor shoe business would be handled in a boarding school. I'm guessing indoor slippers are worn in the dorm with shoelockers in the dorm entrance corridor, so the outdoor shoes are put on to walk across campus to the main building, the indoor slippers being carrie din the hand or a bag...? Then at the main building the outdoor shoes go in the lockers there and the slippers are put on... but I'm totally guessing here.
