One Piece season 16

The sixteenth season of the One Piece anime television series was produced by Toei Animation, and directed by Hiroaki Miyamoto. The season began broadcasting in Japan on Fuji Television from January 6, 2013 to January 12, 2014. Like the rest of the series, it follows the adventures of Monkey D. Luffy and his Straw Hat Pirates. The first of twelve DVD compilations was released on January 8, 2014, with the last being released on June 4, 2014.

The story arc, called "Punk Hazard" (パンクハザード), adapts material from the end of the 66th volume to the end of the 70th volume of the manga by Eiichiro Oda. Having left Fishman Island, the Straw Hats recover a distress signal originating from Punk Hazard. There they discover Caesar Clown, an ex-Navy scientist, experimenting on children. Luffy and the prisoners team up to stop Caesar and his henchmen. An anime original story arc, called "Caesar Retrieval", takes place immediately after the Heart–Hat alliance's departure from Punk Hazard and deals with them rescuing Caesar from a mysterious person in order to take down Doflamingo and Kaido.

Two pieces of theme music are used for the season. The opening themes are "We Go!" (ウィーゴー!) performed by Hiroshi Kitadani, used up until episode 590, and "Hands Up!" performed by Kōta Shinzato (新里 宏太) for the rest of the season. When the season originally aired "Hands Up!" was not used by Funimation in its simulcast due to licensing issues with the record label. These licensing issues were later resolved and Funimation restored the song for its original release.
