The twentieth season of the One Piece anime television series is produced by Toei Animation and directed by Tatsuya Nagamine, Satoshi Itō and Yasunori Koyama. The season was broadcast in Japan on Fuji Television from July 7, 2019, to December 17, 2023. On April 19, 2020, Toei Animation announced that the series would be delayed due to the ongoing COVID-19 pandemic. They later scheduled the series' return for June 28, 2020, resuming from episode 930. On March 10, 2022, it was announced that the series would be delayed until further notice due to a security breach in Toei Animation's network on March 6, 2022. On April 5, 2022, it was announced that the series would return on April 17, 2022, with the airing of episode 1014.
Like the rest of the series, this season follows the adventures of Monkey D. Luffy and his Straw Hat Pirates. The main story arc, called "Wano Country", adapts material from the rest of the 90th volume to the beginning of the 105th volume of the manga by Eiichiro Oda. It deals with the alliance between the pirates, samurai, minks and ninja to liberate Wano Country from the corrupt shogun Kurozumi Orochi, who has allied with the Beast Pirates led by one of the Four Emperors, Kaido. Episodes 895 and 896 contain an original story arc, "Cidre Guild" which ties into the film . Episode 907 is an adaptation of Oda's one-shot manga Romance Dawn, which features "the story of a Luffy slightly different from the one in One Piece". Episodes 1029 and 1030 constitute a tie-in making up the “Uta’s Past” arc, taking place over a decade before the present and following Luffy's childhood interactions with Uta, the adoptive daughter of "Red Haired" Shanks.
Seven pieces of theme music are used for this season. From episodes 892 to 934, the first opening theme is "Over the Top" by Hiroshi Kitadani. From episodes 935 to 999 and 1001 to 1004, the second opening theme is "Dreamin' On" by Da-ice. For episode 1000, the special opening theme is "We Are!" by Hiroshi Kitadani. From episodes 1005–1027 and 1031–1073, the fourth opening theme is "Paint" by I Don't Like Mondays. From episodes 1028–1030 and recap special 4 (1030.5), in the Japanese broadcast only due to licensing issues and to promote Film: Red, the special opening theme is the theme song of the aforementioned film, by Ado, the vocalist of the character from the aforementioned film, Uta. From episodes 1074 to 1088, the fifth opening theme is by Sekai no Owari. From episodes 1071 to 1088, the first ending theme is "Raise" by Chili Beans, which marked the first ending theme for the series in 17 years.__TOC__
