Perfume are the latest celebrities to appear in the React series done by the Fine Brothers. In the video, they react to a over four-year-old Teens React video, where they’re shown Perfume, EXILE, and AKB48 music videos.
Thought it was noteworthy that they don’t consider themselves J-pop, even though they are frequently used to represent J-pop in the West.
Also, I can’t tell if they were showing support for indie Japanese artists at one point or if there was something lost in translation.
