The most important responsibility children have while growing up is going to school to learn. Although children may groan about waking up early and doing homework, the education they receive in the long run will be worth it.
However, every learning environment is different. They each have their own set of rules that must be followed, some more strict than others. For example, Japan has a school structure very much different from America's. Here a few of their strict rules that you probably didn't know existed.
But it is especially important in Japan. Students are expected to be at school at 8:30 AM sharp! If they come to school late more than 5 times, they're punished with cleaning responsibilities even earlier in the morning for an entire week.
