Since the 1960s manga has boasted a firm standing in the Japanese economy and society by continuously offering captivating and commercially successful narratives. This has been made possible in great measure by the manga magazines as the central venue of publication from the 1960s until the late 1990s, and their editor-in-charge system. This chapter surveys the multiple roles that manga editors fulfill, from corporate agent to manga artists’ collaborator and target-audience representative. It introduces the basic institutional steps of producing a manga serial while considering differences between printed and digital formats, up to and including remuneration practices. The main focus is on corporate manga’s commodity value as the common goal of both editors and artists, as well as the related fact that readership, or consumption, is given precedence over authorship, and collaborative over individual authorship.
