One Piece (ワンピース Wan Pīsu ) is a Japanese shōnen manga series written and illustrated by Eiichiro Oda, that has been serialized in Weekly Shōnen Jump since August 4, 1997. The individual chapters are being published in tankōbon volumes by Shueisha, with the first released on December 24, 1997, and the 61st volume released as of February 2011. In 2010, Shueisha announced that they sold over 200 million volumes of One Piece manga so far; volume 61 set a new record for the highest initial print run of any book in Japan in history with 3.8 million copies (the previous record belonging to volume 60 with 3.4 million copies). Volume 60 is the first book to sell over two million copies in its opening week on Japan's Oricon book rankings.[1] One Piece follows the adventures of Monkey D. Luffy, a 17-year-old boy who gains elastic abilities after inadvertently eating a mystical fruit, and his diverse crew of pirates, named the Straw Hats. Luffy explores the ocean in search of the world's ultimate treasure known as the One Piece and to become the next Pirate King. On his journey, Luffy battles a wide variety of villains and makes several friends.
The series has been adapted into an original video animation (OVA) produced by Production I.G in 1998, and an anime series produced by Toei Animation, which premiered in Japan in 1999.
