Year 24 Group

Year 24 group (nijuyon-nen gumi/24年組) is a female manga artist group that innovated "shōjo manga" (girl's manga). They are said to make manga a literature. Many of them were born in Year 24　(Shōwa era, 1949.). Several of the members are Yasuko Aoike, Moto Hagio, Riyoko Ikeda, Yumiko Ōshima, Keiko Takemiya, Ryoko Yamagishi.

Moto Hagio and Keiko Takemiya once lived in the same apartment in Ōizumi Nerima-ku Tokyo around 1970-1973. The circumstances was like Osamu Tezuka's Tokiwa-so in appearance. But in those days as it was, shojo manga (girl's manga) was mainly written by male manga artist like Osamu Tezuka's "Ribbon no Kishi (Princess Knight)". So their attempts to write shojo manga by female manga artists were pioneering acts of one kind of women's occupation.

Fortunately their mangas were welcomed by not only girls but also women and men. And their pioneering acts and success arranged the appearances of many female manga artists like Rumiko Takahashi.

Comiket, the world's largest comic convention was hatched by the dojinshi circle "Meikyu (迷宮)" which has distinctive character of a society for the study of Moto Hagio.
