Japanese school uniforms, often recognized globally, and the teens' customary practice of "wearing them casually" are seemingly undergoing a change. The news discusses an apparent shift in perception among Japanese students and institutions, where the "casual uniform" trend might be seen as antiquated. It delves into the possible reasons, including the rising emphasis on discipline and decorum, as well as contemporary fashion trends among teenagers.

Japan's school uniforms have become cultural symbols, and the way students wear them (neatly or casually) often reflects societal attitudes at large. Recently, many schools are leaning towards stricter uniform regulations, highlighting the importance of discipline and decorum. Public opinion is also divided on this issue — some view the shift as a necessary move towards orderliness, while others see it as stifling individual expression.

In U.S. or EU, school uniforms are less common and there's a stronger focus on individual expression through clothing. If implemented, uniform regulations are generally stricter and deviation isn't common. The concept of casualizing uniforms as a form of self-expression is largely unfamiliar.
