It’s not surprising that the sales for the One Piece manga volumes have decreased over time. After all, One Piece was first published in 1997, and Shonen Jump is primarily geared towards children. Many young kids today may not be familiar with One Piece, and those who are might be older teenagers or young adults. With sales dropping for almost three decades, it’s no wonder there’s been a decline.
In the first half of 2025, Jujutsu Kaisen outsold One Piece in annual sales, as per Oricon charts, with some even calling Jujutsu Kaisen the next-generation manga. Although One Piece released a new volume since then, it seems unlikely that it’ll be the best-selling manga of 2025 overall.
