The story follows the adventures of Monkey D. Luffy, a boy whose body gained the properties of rubber after unintentionally eating a Devil Fruit.

On October 13, 2024, it was announced that the series' Egghead story arc would enter on a six-month hiatus and is set to resume in April 2025, having a new time slot on Fuji TV.

[7] On December 22, 2024, it was announced that the series is set to return with new episodes on April 6, 2025, airing on Sundays at 11:15 p.m. on Fuji TV and its affiliates.

However, once 4Kids realized One Piece was not appropriate for their intended demographic, the company decided to edit it into a more child-oriented series until they had an opportunity to legally drop the license.

[14] On April 13, 2007, Funimation (later Crunchyroll, LLC) licensed the series and started production on an English-language release of One Piece[15] which also included re-dubbing the episodes previously dubbed by 4Kids.

In an interview with voice actor Christopher Sabat, he stated that Funimation had been interested in acquiring One Piece from the very beginning, and produced a "test episode," in which Sabat portrayed the character of Helmeppo and Eric Vale played the part of the main character, Monkey D. Luffy.

[20] On May 18, 2013, the uncut series began airing on Adult Swim's revived Toonami late-night programming block skipping ahead to episode 207 onward.

[24] In May 2009, Funimation, Toei Animation, Shueisha, and Fuji TV announced they would simulcast stream the series within an hour of the weekly Japanese broadcast at no charge.

[26][27][28] On February 12, 2013, it was announced that Manga Entertainment would start releasing the Funimation dub of One Piece in the United Kingdom in a DVD box set format.

[29] Crunchyroll began simulcasting the series on November 2, 2013, for the United States, Canada, South Africa, Australia, New Zealand, and Latin America.

[31] In April 2020, Netflix officially announced that they would be streaming One Piece starting on June 12 of the same year, for the United States, Canada, Australia, and New Zealand, using the "Special Edition" print.

In episodes 1–206 of Crunchyroll's English-language release of the series, the opening and ending themes were dubbed into English by various voice actors, before reverting to the Japanese versions from episodes 207 onwards and some openings were not licensed by Funimation's release at the time, which is also affected by all territories.

Douglass said that the 4Kids original opening was "a crappy rap song" and that the removal of whole scenes leaves a "feeling that something is missing".

[52] Margaret Veira of activeAnime praised the TV series' "great" animation, stating that "It gives life and stays true to the style and characters of the manga."

"[56] In Indonesia, Global TV was reprimanded by the Indonesian Broadcasting Commission (KPI) for airing the anime television series.

Nina Armando, member of the KPI and a lecturer at the University of Indonesia, said the show should not be aired at times when children are likely to watch.
