One Piece (stylized in all caps) is a Japanese manga series written and illustrated by Eiichiro Oda. It follows the adventures of Monkey D. Luffy and his crew, the Straw Hat Pirates, as he explores the Grand Line in search of the mythical treasure known as the “One Piece” to become the next King of the Pirates.
It has been serialized in Shueisha’s shōnen manga magazine Weekly Shōnen Jump since July 1997, with its chapters compiled in 111 tankōbon volumes as of March 2025. The manga series was licensed for an English language release in North America and the United Kingdom by Viz Media and in Australia by Madman Entertainment. Becoming a media franchise, it has been adapted into a festival film by Production I.G, and an anime series by Toei Animation, which began broadcasting in 1999. Additionally, Toei has developed 14 animated feature films and one original video animation. Several companies have developed various types of merchandising and media, such as a trading card game and video games. Netflix released a live action TV series adaptation in 2023.
One Piece has received praise for its storytelling, world-building, art, characterization, and humour. It has received many awards and is ranked by critics, reviewers, and readers as one of the best manga of all time. By August 2022, it had over 516.6 million copies in circulation in 61 countries and regions worldwide, making it the best-selling manga series in history, and the best-selling comic series printed in a book volume. Several volumes of the manga have broken publishing records, including the highest initial print run of any book in Japan. In 2015 and 2022, One Piece set the Guinness World Record for “the most copies published for the same comic book series by a single author”. It was the best-selling manga for 11 consecutive years from 2008 to 2018 and is the only manga that had an initial print of volumes of above 3 million continuously for more than 10 years, as well as the only one that had achieved more than 1 million copies sold in all of its over 100 published tankōbon volumes. One Piece is the only manga whose volumes have ranked first every year in Oricon’s weekly comic chart existence since 2008.
One Piece is set on the Blue Planet, populated by humans and other races such as dwarves (more akin to fairies in size), giants, merfolk, fish-men, long-limbed tribes, long-necked people known as the Snakeneck Tribe, and animal people (known as “Minks”). The Blue Planet is governed by an intercontinental organization known as the World Government, consisting of dozens of member countries. The Navy is the sea military branch of the World Government that protects the known seas from pirates and other criminals. There is also Cipher Pol which is a group of agencies within the World Government that are their secret police. While pirates are major opponents of the Government, the ones who challenge their rule are the Revolutionary Army who seek to overthrow them. The central tension of the series pits the World Government and their forces against pirates. The series regularly emphasizes moral ambiguity over the label “pirate”, which includes cruel villains, but also any individuals who do not submit to the World Government’s authoritarian—and often morally ambiguous—rule. The One Piece world also has supernatural objects such as Devil Fruits,[Jp 1] which are mysterious fruits that grant whoever eats them transformative powers at the cost of becoming weakened in bodies of water, resulting in them losing the ability to swim. Another supernatural power is Haki,[Jp 2] which grants its users enhanced willpower, observation, and fighting abilities, and it is one of the only effective methods of inflicting bodily harm on certain Devil Fruit users.
The surface of the Blue Planet mainly consists of the Blue Sea, two vast oceans divided by a massive continental mountain range called the Red Line.[Jp 3] Within the oceans is a second global phenomenon known as the Grand Line,[Jp 4] which is a sea that runs perpendicular to the Red Line and is bounded by the Calm Belt,[Jp 5] strips of calm ocean infested with huge ship-eating monsters known as Sea Kings.[Jp 6] These geographical barriers divide the world into four seas: North Blue,[Jp 7] East Blue,[Jp 8] West Blue,[Jp 9] and South Blue.[Jp 10] Passage between the four seas, and the Grand Line, is therefore difficult. Unique and mystical features enable transport between the seas, such as the use of Sea Prism Stone[Jp 11] employed by government ships to mask their presence as they traverse the Calm Belt, or the Reverse Mountain[Jp 12] where water from the four seas flows uphill before merging into a rapidly flowing and dangerous canal that enters the Grand Line. The Grand Line itself is split into two separate halves with the Red Line between being Paradise[Jp 13] and the New World.[Jp 14]

The series focuses on Monkey D. Luffy—a young man made of rubber after unintentionally eating the Gum-Gum Fruit—who sets off on a journey from the East Blue Sea to find the deceased King of the Pirates Gol D. Roger’s ultimate treasure known as the “One Piece”, and take over his prior title. Luffy sets sail as captain of the Straw Hat Pirates,[Jp 15] and is joined by Roronoa Zoro, a swordsman and former bounty hunter; Nami, a money-obsessed thief and navigator; Usopp, a sniper and compulsive liar; and Sanji, an amorous but chivalrous cook. They acquire a ship, the Going Merry[Jp 16]—later replaced by the Thousand Sunny[Jp 17]—and engage in confrontations with notorious pirates. As Luffy and his crew set out on their adventures, others join the crew later in the series, including Tony Tony Chopper, an anthropomorphized reindeer doctor; Nico Robin, an archaeologist and former Baroque Works assassin; Franky, a cyborg shipwright; Brook, a skeleton musician and swordsman; and Jimbei, a whale shark-type fish-man and former member of the Seven Warlords of the Sea who becomes their helmsman. Together, they encounter other pirates, bounty hunters, criminal organizations, revolutionaries, secret agents, scientists, soldiers of the morally ambiguous World Government, and various other friends and foes, as they sail the seas in pursuit of their dreams.
