J-pop is an abbreviation of Japanese pop. It refers to Japanese popular musicians, and was coined by the Japanese media, to distinguish Japanese musicians from foreign musicians. Today, the Japanese music industry is the second most powerful in the world (behind the United States) and while extremely hard to define, it´s considered by some as a style, though in essence, it refers to modern Japanese music outside of traditional Japanese music and early-modern Japanese genres like enka and kayōkyoku. .
