Minmi began playing the piano at the age of five, at which time she began to take interest in soul and jazz music. Minmi began her musical career in 1996, performing at rub-a-dub showcases and hip hop events in the clubs of Osaka. She also began to develop her own sound by making her own original tracks around this period. Minmi signed her first recording deal with JVC Records, releasing the reggae song "The Perfect Vision" as her first single in August 2002. Minmi's first single became extremely popular, and was widely accepted and heavily rotated by as many as 20 FM radio stations. "The Perfect Vision," after gradually increasing in popularity, would eventually sell over 500,000 copies. Her second single, "T.T.T.," differed stylistically, more influenced by hip-hop. The single was a moderate success, peaking in the top 10. These were followed by Minmi's debut albumMiracle, which debuted at #2 and has sold more than 600,000 copies. Minmi continued her success in 2004, with her second albumImagine, which was also a high seller. In 2004, she contributed the song "四季ノ唄 Shiki no Uta" to the anime Samurai Champloo, where it appears as the end credits theme. In 2005, Minmi released her first soca-influenced song, "Summertime!!," as opposed to her regular reggae and hip-hop sound. Because of this event, she attended the Trinidad and Tobago Carnival in February 2006, performing on stage. In September, she was nominated for best new artist at the Reggae/Soca Music Awards in New York. Minmi attended the festival again in 2007, performing "Sha Na Na " with Machel Montano. In June 2007, it was suddenly announced that Minmi had married Wakadanna, a member of reggae group Shōnan no Kaze, and was four months pregnant. The two had first met in 2001 in Jamaica, and began dating soon after. In November she gave birth to her first child, a son. In March 2010 it was announced that Minmi was pregnant with her second child. Her fourth album Mother, released in July when she was roughly eight months pregnant, prominently features her stomach in the photographs. The child, the second boy, was born ten days early on August 4 in New York. On June 10 and July 22, 2015, Minmi released her seventeenth single "Hologram".
