Literally "a female high school student", but the term is invariably used to refer specifically to cute high school girls wearing Sailor Fuku, or sailor suit-styled uniforms. Note that the term may be used interchangeably with 'seifuku', which means any general "school uniform", but is often used to describe the sailor outfits in particular. Although seeraafuku are not as common now in Japan as they once were, the vast majority of anime girls still wear them.
Many Japanese men refer to them under the nickname "JK" or "JC". That Japanese has such a compact, productive phrase for this image implies that it's an important archetype in the Japanese psyche, and this is borne out by how often sailor-suited school girls still appear in both manga and anime.
See also School Swimsuit, for when the girls wear something that shows a little more skin.
This is mainly a Japanese cultural trope but is found prominently in anime. The Western equivalent is Catholic School Girls Rule. However, given that many Japanese high schools have abandoned the sailor uniform, which nowadays is a characteristic indicator of middle school girls, more professional-esque styles of uniform have become a popular replacement - popular not just among schools but also among viewers - so the two are beginning to merge. Joshikousei are very prominent in anime/manga, to the point where the far majority of female characters will be either be high school girls or at the very least be in the same age group (should high school not exist or should their occupation prevent them from going to school). In fact, one of the main reasons why most male protagonists are ordinary highschool students is so they can be surrounded by high school girls.

- In Soul Eater, the girls' Spartoi uniforms usually are in the sailor style.
- Kim and Jackie's original uniform also slightly resembles a seifuku, having the colar and tie.

- Kamen Rider Agito: Kazaya Mana is a less straight example, since she doesn't wear the sailor suit.

- Kamen Rider OOO: Mezuru's guise is a school girl... for about one episode. Then she changes into another outfit. One wonders why...
