One Piece Novels

Twenty three light novels based on One Piece have been published in Japan by Shueisha. Six of these novels are original, meaning their story is not based on existing media. The other seventeen are adaptations of the anime and movies.

Thirteen of the novels have been re-released as a "Mirai Bunko Edition" (みらい文庫版). Mirai Bunko is Shueisha's imprint which publishes books for younger children, with simpler language.

Novel Adaptations
The novel adaptations are mostly authored by Tatsuya Hamazaki (浜崎 達也). The only exceptions are the Mirai Bunko Editions of the One Piece: Stampede novel and the One Piece Film: Red novel, which are authored by Mochitaro Shida (志田 もちたろう), and the One Piece Film: Red novel, which is authored by Jun Esaka (江坂 純).
