4. Wearing indoor shoes
Once at a school, students are normally provided with lockers or shoe racks, where they have to place their outdoor shoes and wear uwabaki (Japanese indoor slippers) before entering a class. The main purpose of wearing indoor shoes is to keep cleaning and maintaining the floor to a minimum, since there are no janitors in the building.
5. No snacks and instant ramens at school
Sugary snacks and processed foods are banned in most of the school compounds as they provide little to no nutritional benefit. Allowing such foods can contribute to the development of many health problems, like tooth decay, obesity, heart disease and high blood pressure. The students often eat school lunches or boxed lunches that are usually made by their mothers in the early morning, which consist of rice, eggs, fish, fruits and vegetables, or such.
