TWICE and BTS have also taken over Japan.
Just recently, Billboard Japan announced the 2018 mid-year rankings including 'Top Artists', 'Hot 100', 'Hot Albums', and more.
The 'Top Artists' list is based on the artist's radio play count, download, streaming, YouTube views in Japan, and other criteria.
Popular K-Pop groups, TWICE and BTS, overcame other top J-Pop artists and snagged #2 and #3 on the 'Top Artists' list, respectively. They're also the only K-Pop stars on the ranking.
Both TWICE and BTS have actively promoted in Japan with Japanese albums.
Not only that, TWICE ranked #7 on the 'Hot 100' with "Candy Pop" while BTS ranked #10 on the same chart with "MIC DROP". BTS also ranked #7 on the 'Hot Albums' list with 'Face Yourself'.
