The New King of Manga Sales: Space Brothers
After spending three consecutive weeks at the top of Japan's official manga sales rankings, One Piece has finally been knocked out of the number one spot by the returning hit series Space Brothers with the release of its newest and final volume.
According to Oricon's latest weekly manga rankings by individual volume sales, Space Brothers Vol. 46 debuted at number one for the week, pushing One Piece Vol. 115 down to fourth place after its three-week run atop the charts.
The Sales Figures
The newest volume of Chuya Koyama's acclaimed space drama manga was released in Japan on July 22, 2026, marking the series' first new collected volume in almost exactly one year following the release of Vol. 45 on July 23, 2025. It is also the manga's final volume, marking the end of Space Brothers after roughly 19 years of serialization.
Space Brothers Vol. 46 sold an estimated 138,012 copies during the week, narrowly edging out The Apothecary Diaries Vol. 17, which followed close behind with an estimated 133,530 copies sold.
One Piece Falls from the Top
While One Piece Vol. 115 spent three consecutive weeks at the top of Japan's official manga sales rankings, it was knocked down to fourth place by the release of Space Brothers Vol. 46, with The Apothecary Diaries Vol. 17 and Medalist Vol. 15 taking the second and third spots respectively.
The complete top 10 in Oricon's latest weekly manga sales rankings is as follows:
- Space Brothers Vol. 46
- The Apothecary Diaries Vol. 17
- Medalist Vol. 15
- One Piece Vol. 115

- Smoking Behind the Supermarket with You Vol. 9
- Giant Killing Vol. 70
- Hunter x Hunter Vol. 39

Despite falling from the top spot, One Piece continues to be one of the year's strongest-selling manga, with the franchise expanding across multiple fronts with the return of the anime's Elbaf Arc and the second season of Netflix's live-action adaptation.
Space Brothers first debuted in Kodansha's Morning magazine in 2007 and follows brothers Mutta and Hibito Nanba as they work toward fulfilling a childhood promise to become astronauts.
