What is Shoujo? A type of anime or manga directed at a particular demographic! More info here.
Shoujo (少女), also written as Shōjo and Shojo, is a Japanese term used to categorize anime or manga commonly aimed at young women in their teens. In fact, the word Shoujo means girl.
This type of anime and manga typically have teenage females in the lead role, and feature romance or stories with a lot of emotion and drama. Those that feature male main character often have homoerotic stories. However, like with Shounen, Shoujo anime and manga don’t always follow these specific parameters. These days many Shoujo anime and manga cover various genres and may even feature a ton of action. Notable examples of Shoujo anime and manga include: Sailor Moon, Cardcaptor Sakura, Lovely Complex, and Clannad.
This is just one of five different types of Anime and Manga directed at certain demographics. For more demographic groups, see my articles on Kodomomuke, Shounen, Seinen, and Josei. And don’t forget, you can find more information on subculture terms just like this in my growing Otaku Encyclopedia.
