Puffy AmiYumi is a Japanese rock duo currently signed with Sony Music Japan. In Japan, they are known as PUFFY, while outside of the country, they use the name Puffy AmiYumi to avoid legal conflicts with Sean Combs. They sing in both Japanese and English. The group was formed by talent agencies affiliated with Sony in the mid-1990s, consisting of Ami Onuki (nicknamed Jane) and Yumi Yoshimura (nicknamed Sue). Puffy gained mainstream success in Japan following the release of their Jet album and supporting tour in 1998. Their debut single "Asia no Junshin" sold a million records, and they have since released several more full-length albums, totaling 14 million sales in Japan.
