Japanese schools have a strict dress code policy that includes restrictions on hair length. Students must wear uniforms that conform to specific standards set by each school, including the length of skirts and hair. Boys' hair must not touch their ears or collar, while girls' hair must be either short or tied up in a specific way. Breaking the rules can lead to penalties such as detention or suspension from school. While there are exceptions for traditional cultural activities, it is important for schools to strike a balance between promoting discipline and allowing students to express themselves within reasonable limits.
