How many copies has Slam Dunk sold?

The documented milestones tell the story cleanly. Slam Dunk passed 100 million copies in circulation in Japan in 2004, the occasion Inoue marked by drawing the 10 Days After epilogue in chalk. By the early 2020s Japanese reporting placed the series above 120 million copies in Japan, and the film's official franchise materials describe worldwide sales across thirty countries and regions, with some recent reporting citing figures as high as 185 million copies worldwide.

Because publishers count copies in circulation rather than copies sold through, and because later totals are reported inconsistently between sources, this site anchors on the two firm rungs: 100 million in Japan by 2004, and more than 120 million in Japan since. The worldwide figure is best stated as a range with its sourcing, not a single number.

For context inside Jump history, those numbers put a five-year sports series in the company of decade-long battle manga, which is the commercial fact underneath all the artistic praise.
