It has been serialized in Shueisha's Weekly Shōnen Jump magazine since July 22, 1997, and has been collected into 96 tankōbon volumes as of April 2020. The story follows the adventures of Monkey D.

The manga spawned a media franchise, having been adapted into a festival film produced by Production I.G, and an anime series produced by Toei Animation, which began broadcasting in Japan in 1999.
