Since the Meiji era, school education statutes have consistently prohibited corporal punishment. However, corporal punishment never disappeared from schools. We have to consider the reasons why teachers are unable to avoid them. The Supreme Court of Japan has ruled that corporal punishment is illegal, but that teachers could adopt certain forms of “physical contact” in the course of instruction. Their conduct becomes illegal only when they abuse their power. Case law indicates that a decision on whether they abused it is made after considering all circumstances, for example the necessity to use force, purpose of instruction, and method of discipline.
