* Seifuku (制服): This is the most common type of uniform and is often what people picture when they think of Japanese school uniforms. Seifuku typically consists of a sailor-style uniform (for girls, often a white blouse with a dark blue or black sailor collar and pleated skirt) or a blazer-style uniform (for both boys and girls, often a blazer, shirt, and trousers or skirt). Variations abound, with different schools having different colors and styles.
* Hakama (袴): Traditionally worn for formal occasions, some schools, particularly private schools or those with a strong traditional emphasis, may incorporate hakama (pleated, wide-legged trousers) as part of their uniform, especially for girls on special occasions or ceremonies.
* Other variations: Some schools might have unique styles or less formal uniforms, but the seifuku remains the most prevalent.
It's important to remember that there's no single "Japanese school uniform." The specific requirements—colors, styles, and accessories—vary significantly from school to school.
