The Moribito series is a twelve volume series of Japanese fantasy novels, written by Nahoko Uehashi. The first novel in the series, Guardian of the Spirit, has been adapted into numerous media, including a radio drama, manga series, and an anime adaption. Scholastic released the first novel in English in June, 2008. The English translation of the first book, published by Arthur A. Levine Books, appeared in the summer of 2008; the second book’s translation appeared in April 2009. Due to unsatisfactory sales, publishing of the series in the U.S. has since been indefinitely suspended by Scholastic.
Moribito is set in a fantasy analogue of historical Asia. The setting includes several nations, such as Kanbal, a rugged, Himalayan-like kingdom, and New Yogo, a fertile empire that combines elements of feudal Japan and Southwest China. The supernatural plays very prominently into the world of the series, with the physical world being referred to as Sagu and a parallel spirit world being referred to as Nayug.
