講談社BOX

Kodansha Box (講談社BOX, Kōdansha BOX) is the name of a book label published since November 2006 and a division of the major Japanese publishing house, Kodansha. The label published not only novels but also manga and critical review books, advocating a "hybrid label." The label was originally characterized by its silver boxed binding, but since November 2010, it has been publishing the "Powers BOX" label, dedicated to Kodansha BOX Newcomer Award "Powers" award-winning works, in a different binding in parallel, and in its final years, it mainly published books in softcover.

From its inception, the label sponsored the Kodansha Box Newcomer Award, and actively introduced new authors and illustrators to the world. It also published the magazine Pandora from 2008 to 2009 and the electronic magazine BOX-AiR from February 2011. Editor Katsushi Ōta described the label as: "A collection of works on the theme of adolescent self-consciousness. I hope it becomes an index of Japanese popular culture."
