Shoujo manga

Shōjo, shojo, or shoujo manga (少女漫画, shōjo manga^?) is manga aimed at a teenage female readership. The name romanizes the Japanese (), literally "young woman". Shōjo manga covers many subjects in a variety of narrative styles, from historical drama to science fiction, often with a focus on romantic relationships or emotions. Strictly speaking, however, shōjo manga does not comprise a style or genre, but rather indicates a target demographic.

Japanese magazines specifically for girls, known as shōjo magazines, first appeared in 1903 with the founding of Shōjo kai (少女界^?, Girls' World) and continued with others such as Shōjo Sekai (少女世界^?, Girls' World) (1906) and the long-running Shōjo no tomo (少女の友^?, Girls' Friend) (1908).

The roots of the wide-eyed look commonly associated with shōjo manga dates back to early shōjo magazine illustrations during the early 20th century. The most important illustrators associated with this style at the time were Yumeji Takehisa and particularly Jun'ichi Nakahara, who, influenced by his work as a doll creator, frequently drew female characters with big eyes in the early 20th century. This had a significant influence on early shōjo manga, evident in the work of influential manga artists such as Makoto Takahashi and Riyoko Ikeda.
