Osamu Dazai's 1939 novella depicts a day in the life of a Tokyo schoolgirl. Propelling Dazai into the literary elite of post-war Japan, Schoolgirl gained notoriety for its ironic and inventive use of language. Now it illuminates the prevalent social structures of a lost time, as well as the struggle of the individual against "them" -- a theme that occupied Dazai's life both personally and professionally. This new translation preserves the playful language of the original and offers the reader a new window into the mind of one of the greatest Japanese authors of the 20th century.
