One Piece Season 15

Swipe One Piece Season 15 Vs...

The fifteenth season of the One Piece anime television series was produced by Toei Animation, and directed by Hiroaki Miyamoto. The season was broadcast in Japan on Fuji Television on October 2, 2011 to December 23, 2012. Like the rest of the series, it follows the reunion of Monkey D. Luffy and his Straw Hat Pirates after two years later of completing their training sessions to rejoin their adventures. The first of fourteen DVD compilations was released on December 5, 2012, and the last one was released on December 3, 2013.

The main story arc, called "Fishman Island" (魚人島, Gyojin-tō), adapts material from the 61st to the end of the 66th volumes of the manga by Eiichiro Oda. Two years have passed since the war at Marineford, and Luffy and the Straw Hats reunite at Sabaody after completing their training sessions. From there, they head off to Fishman Island. However, they end up facing Hordy Jones who plots to use a coup d'état to take control of Fishman Island. The final four episodes contain an anime original story arc, called "Z's Ambition" (Zの野望編, Zetto no Yabō), which serves as a prologue to the concurrently released One Piece Film: Z.

Only a single piece of theme music is used for this season. The opening theme, titled "We Go!" (ウィーゴー!), is performed by Hiroshi Kitadani.

In October 2024, it was announced that the anime series would go on hiatus until April 2025 for the "Egghead" story arc, and that a remastered and re- edited version of the "Fishman Island" story arc would air in the show's timeslot during the break.
