How did One Piece become the best-selling manga series in history?

The answer

Eiichiro Oda's One Piece, which began serialization in Shueisha's Weekly Shonen Jump on July 22, 1997, has sold over 500 million copies worldwide, making it the best-selling manga series in history. Oda has maintained a grueling weekly chapter schedule for over 25 years, rarely taking breaks. The story follows Monkey D. Luffy and his pirate crew searching for the legendary treasure 'One Piece.' The manga holds the Guinness World Record for most copies published for the same comic book series by a single author. In Japan alone, it has sold over 400 million copies. The 2023 Netflix live-action adaptation further boosted global popularity, becoming the platform's most-watched series in 46 countries during its debut week.
