2000

The year 2000 marked the peak of Japan's CD singles boom, with sales routinely exceeding one million copies. Southern All Stars returned after a three-year hiatus with 'Tsunami', which became the best-selling single in Japanese chart history. The era featured a diverse mix of veteran rock acts, idol groups like Morning Musume, and solo J-pop artists such as Utada Hikaru and Hamasaki Ayumi defining a new sound for the decade.
