Japanese popular music has deep roots. In its modern form, it began to spread more widely in the 1990s. At that time, j-pop songs began to occupy space in advertisements, shops, movies, and video games. Today, the term “j-pop” refers to Japanese pop music, which encompasses several different genres such as pop, rock, dance, rap, or soul. In addition to the music, the style and aesthetics, the personalities of idols, and the internal dynamics of bands are also of great interest in Japanese music. J-music reached Finland in the 1990s.
