Premiering in July 1997, One Piece has currently published over 1000 chapters (collected into 100 tankōbon volumes) and generated a massive franchise, including an anime adaptation from Toei Animation, many feature films, and countless other pieces of merchandise. Since the late 2000s it has been recognized as Japan's most popular manga, even being commemorated by the Guinness World Records as the world's best-selling single-author comic book.
One Piece is divided into two halves: Sea of Survival: Super Rookies Saga (サバイバルの海 超新星編 Sabaibaru no Umi: Chōshinsei-hen?), and The Final Sea: The New World Saga (最後の海 新世界編 Saigo no Umi: Shinsekai-hen?).
