I hadn't really been paying attention, but then I saw the Japanese album sales of some groups, and that's when I start to notice: excluding BTS, have the Japanese album sales decreased of K-pop groups and artists over the years?
Compared with 10 years ago, the overall album sales of K-pop artists has easily increased 5 times and more across the whole line (not sure if the same can be said for album revenues, but I'm guessing that increased too).
However, when you check the Japanese album sales it's a lot less when you consider that early 2010s SNSD and Kara sold 0.5-1 million Japanese albums, something that current girl groups don't even come close to.
Or does this only apply to K-pop girl groups and not the boy groups?
Or is this a general Japanese trend, and are the Japanese groups and artists also selling far fewer Japanese albums than they used to 10 years ago?
I recall AKB48 sold 1-2 million of their albums too 10 years ago, but when I check their sales now, that's far below their sales back then too. But that's maybe due to AKB48 not being that popular anymore and not a general trend.
Anybody knows? Maybe this was already common knowledge, but I hadn't really been paying attention to album sales in Japan by K-pop groups (or J-pop groups), so I'd just assumed they had increased since all the K-pop album sales have tripled and more.
