Yuri (百合, "lily"), also known by the wasei-eigo construction Girls' Love (ガールズラブ gāruzu rabu), is a Japanese jargon term for content and a genre involving lesbian relationships in light novels, manga, anime, video games and related Japanese media. Yurifocuses on the sexual orientation or the romantic orientation aspects of the relationship, or both, the latter of which is sometimes called shōjo-ai by Western fandom.
The themes yuri deals with have their roots in the Japanese lesbian fiction of the early twentieth century, with pieces such as Yaneura no Nishojo by Nobuko Yoshiya. Nevertheless, it is not until the 1970s that lesbian-themed works began to appear in manga, by the hand of artists such as Ryoko Yamagishi and Riyoko Ikeda. The 1990s brought new trends in manga and anime, as well as in dōjinshiproductions, along with more acceptance for this kind of content. In 2003, the first manga magazine specifically dedicated to yuri, Yuri Shimai, was launched, and this was followed by its revival Comic Yuri Hime, which was launched after the former was discontinued in 2004.
As a genre, yuri content could target either a male or a female audience. Although yuri originated in female-targeted (shōjo, josei) works, today it is featured in male-targeted (shōnen, seinen) ones as well. Yuri manga from male-targeted magazines include titles such as Kannazuki no Miko and Strawberry Panic!, as well as those from Comic Yuri Hime's male-targeted sister magazine, Comic Yuri Hime S, which was launched in 2007.
