So, how well does One-Punch Man sell?
I posted this a few months ago on r/onepunchfans but don't think I put it here. Rectifying that now.
Have you ever wondered about the discrepancy between the number of issues the manga claims to have sold (34 million copies as of volume 33) and the number that are reported to sell via Omicron?
Firing on all cylinders, apparently.
Well, as you are no doubt aware, the manga sales publicly reported represent only the printed sales. Digital sales aren't publicly available. But they are collected.
My company has a subscription to Statista, and I had a wee bit of a shufti at the Japanese manga market. I'm going to put up two charts describing sales from 2015--2024.
First, manga is in rude health in Japan, with sales strongly growing over the last decade, with the value of sales nearly doubling. It should be noted that inflation in Japan is extremely low, with a mean annual rate of 1.14% in this period (source).
Secondly, this growth in sales has increasingly moved online with digital sales accounting for two-thirds of the value. Digital sales have increased nearly fivefold.
And, yes, there has been a corresponding slump in physical sales.
What does this mean? Since the publishers love to sell digital copies at the same cost as physical ones (shame on them), it means that in 2015, for every manga issue sold online, three were sold in stores. As of 2024, that was nearly flipped: for every issue sold in stores, 2.5 were sold online. On average.
For One-Punch Man, which has been an online-first title from the get-go and thus has no first-pass physical sales as part of a magazine (e.g., One Piece), what the discrepancy between physical sales figures (approx 200,000 per volume) and total sales figures (approximately 1 million per volume) mean is that it's selling 4 digital copies for every physical copy sold. That's not unreasonable for a digital title!
Or, in simpler terms, OPM is doing just fine. The 'issue' is that the sales figures publicly reported are increasingly the tip of the iceberg! Eventually, the Japanese manga watchers will enter the 21st century and start capturing digital sales too. Until then, you are better off looking at where OPM ranks in relative sales -- it's doing very well, thanks for your concern.
