The is a Japanese comics award recognizing achievement in manga. It is awarded annually to a manga series published in the previous calendar year of eight or fewer collected volumes in length. The Manga Taishà  was founded with the aim of recognizing new and relatively unestablished manga, and to provide a platform to promote these works to new readers. To this end, the prize utilizes a judging criteria of recognizing manga one would "want to recommend to friends", rather than a strictly meritocratic evaluation of artistic excellence.
The prize is presented by the Manga Taishà  Executive Committee, a volunteer group of roughly one hundred "manga lovers from all walks of life", primarily bookstore workers who manage in-store manga sections. Individuals directly involved with the manga industry, such as manga artists, authors, book designers, and editors, are barred from sitting on the committee; this distinguishes the Manga Taishà  from the majority of the other major manga industry awards, which are typically organized by a specific publishing company and voted on by the company's editors. The Manga Taishà  was established by Nippon Broadcasting System news announcer , who sought to create a prize as a manga equivalent of the Japan Booksellers' Award, a similarly structured award which recognizes literature.
The voting system, also based on that of the Japan Booksellers' Award, is divided into two rounds. In the first round, each committee member nominates five titles, and the top ten titles are shortlisted for the prize. In the event of a tie, both titles are nominated and the shortlist is lengthened; the largest shortlist was in 2012, with fifteen nominees. The second round is a ranked vote, where each member reads each nominated work at their own expense, and selects their top three choices in order of preference. Points are assigned based on rank (three points for first preference, two for second, one for third), the rankings are aggregated, and the title with the most points wins. Winning titles cannot be re-nominated in subsequent years. The Manga Taishà  does not award a cash prize, though winning titles are promoted heavily in bookstores across Japan; the prize is thus recognized as being a significant sales driver for manga, and winning titles are frequently adapted into anime or television dramas.
The inaugural Manga Taishà  was awarded on March 28, 2008, to ' by Shinichi Ishizuka, and in 2026 to Hon Nara Uru Hodo by Ao Kojima. Since its inception, the Manga Taishà  has been awarded annually, with nineteen winners as of 2026. Akiko Higashimura and Yama Wayama are the most-nominated authors, with seven nominations each including Higashimura's win for ' in 2015.
