J-pop has been a major force in Japanese music since the 1990s, with artists like Ayumi Hamasaki, Utada Hikaru, and AKB48 achieving widespread success. J-pop is characterized by its catchy melodies, upbeat rhythms, and highly produced music videos. The genre has also been influenced by Western music, with many Japanese artists incorporating elements of rock, pop, and R&B into their music.
