Kaiju No. 8 manga sales: Oricon history and circulation
Naoya Matsumoto's Shonen Jump+ hit built a reliable annual sales base before its anime adaptation pushed it higher.
Published: 2026-08-19. Updated: 2026-08-19.
Short answer: Kaiju No. 8 ranked 6th on Oricon's 2024 best-selling manga series chart with estimated sales of 3,398,326 copies during the November 20, 2023 to November 17, 2024 tracking period. The manga, which began on Shonen Jump+ in 2020, surpassed 15 million copies in circulation by July 2024.
How Oricon tracks Kaiju No. 8 sales
Oricon's annual manga ranking estimates physical tankobon sales in Japan for each counting year. Kaiju No. 8 started as a Shonen Jump+ digital series in 2020, but its print volumes have appeared on Oricon's charts since 2021.
The ranking excludes digital sales and overseas sales. For a series that originated on a manga app, the Oricon figure is therefore only the print portion of its Japanese sales.
How did sales move year by year?
The table below lists the Oricon fiscal-year ranks and estimated series sales we were able to verify from public year-end charts. Oricon counts physical tankobon sales at tracked retailers, so digital sales and some channels are not included.
A rank tells you how the series performed against every other manga that year, while the sales figure is the estimated number of copies sold during that 12-month window. It is not the same as total copies in circulation.
Kaiju No. 8 Oricon annual series rank and estimated sales, 2021 to 2024.| Year | Oricon tracking period | Series rank | Estimated sales |
|---|
| 2021 | Nov 23, 2020 to Nov 21, 2021 | 11 | 3,705,289 |
| 2022 | Nov 22, 2021 to Nov 20, 2022 | 10 | 3,139,803 |
| 2024 | Nov 20, 2023 to Nov 17, 2024 | 6 | 3,398,326 |
What does the trend show?
Kaiju No. 8 entered the Oricon top 15 in its first full counting year, selling 3.71 million copies in 2021. It held 10th place in 2022 with 3.14 million copies, then improved to 6th place in 2024 with 3.40 million copies after the TV anime aired.
The 2024 improvement came with four new volumes during the tracking window. That suggests both new readers and existing fans were buying, rather than a purely backlog-driven spike.
How do annual sales compare to total circulation?
Oricon NEWS reported in July 2024 that Kaiju No. 8 had surpassed 15 million copies in domestic circulation with the release of volume 13. The figure includes print and digital copies in Japan.
Because the series began on Shonen Jump+, the 15 million circulation number includes digital readers who never appear in Oricon's physical tankobon rankings. The two metrics should be read together, not as duplicates.
Rank versus total sales: A high annual rank means a series sold more copies that year than most rivals. Total circulation counts every volume printed or shipped since the start. A long-running series can have a huge total without topping a single annual chart, while a new hit can top one year with far fewer total volumes.
Where does this fit in the manga market?
Kaiju No. 8 is one of the few Shonen Jump+ originals to become a consistent Oricon top-10 print seller. Its performance shows that a strong digital debut can translate into substantial physical manga sales.
For readers researching manga sales, the cleanest comparison is Oricon annual series rank over the same tracking period. Mixing circulation announcements, digital estimates, and regional sales without labeling them invites confusion.
