From Just their JPN album relase BTS THE BEST's jpn sales (oricon sales) + their back catalogue sales on gaon (no new 2021 release yet).... BTS have already sold 3,366,840 albums in 2021.
Just gaon back catalogue sales they've sold 2.4M of old albums
+ 885,158 of BTS THE BEST (only jpn sales since its oricon, WW it technically has shipped 1.1M but i am using Gaon + Oricon for this number)
+ back catalogue of their JPN releases: 75,744
coming to a total of 960,902 sold on oricon in 2021
so 2,405,938 + 960,902 = 3,366,840 albums sold in 2021 with just BTS THE BESTs JPN sales + back catalogue sales
data from: KOREAN SALES @koreansales_twt - Google Sheets
The fact that they are selling their back catalogue so insanely well just shows that the boys continue to grow.
