Why do almost all teenagers here wear school uniforms — even on weekends?
Nearly every public middle school and most high schools require uniforms — sailor suits, blazers, gakuran. Students wear them to weekend outings and club events too, the designs feature in school choice, and the 'seifuku' is a full-blown cultural icon in anime, idol culture and fashion.
Uniforms came in during the Meiji era, modeled on military and naval dress, as equalizers and symbols of belonging. Your uniform ties you to your school wherever you are — and for students themselves it doubles as identity, and even as fashion.
Why — five layers
Visible wealth differences among children are considered something to suppress; the uniform makes everyone start from the same line each morning.
A uniform makes your behavior in public attributable to your school — misbehave on the train and someone may call your school. That accountability loop is quietly central to how it disciplines.
Meiji-era schools adopted military-style dress (gakuran from Prussian army uniforms, sailor suits from naval wear); school rules (kousoku) then codified every detail, down to sock color and skirt length.
International view
The UK and many Commonwealth countries also have uniforms. What stands out here is the emotional attachment — the uniform as a symbol of youth itself, worn voluntarily on weekends, mourned at graduation, and endlessly reproduced in pop culture.
But not always
The system is being renegotiated: gender-neutral options (slacks for girls) are spreading, 'black kousoku' (unreasonable school rules) face public criticism, and the cost burden on families is a live policy issue.
What to do
Kids in uniform on a Sunday are usually headed to club activities, not class. And remember uniformed students are minors — photographing them, however picturesque, is not okay.
