Puffy AmiYumi transferred to Warner Music Japan in 2015. The group continues to go by the moniker of PUFFY in Japan, but in order to avoid legal naming conflicts with Sean Combs, have adopted the name Puffy AmiYumi in the United States. They sing in Japanese and English.Ami Onuki, whose nickname is Jane, and Yumi Yoshimura, nicknamed Sue, were scouted by Sony-affiliated talent agencies and put together in the mid-1990s. The band gained mainstream success in Japan during 1998, following the release of their Jet album and tour in support of it. Their first release "Asia no Junshin" sold a million records and their success has continued with several more full-length releases (totaling 15 million sales in Japan).
Puffy made their first US appearance as part of Music Japan's "An Evening with Japan's All-Stars" showcase at the 2000 South by Southwest (SXSW) festival in Austin, Texas. After their performance at SXSW, attorneys for Sean "Puffy" Combs sent the band a cease and desist letter asking them to change their name.
The name "Puffy" most likely comes from Andy Sturmer's conscious or unconscious recollection of the night he and his bandmates/friends in the (as of then unnamed) band Jellyfish were trying to come up with funny/catchy band names. "The Puffy" was one of the titles presented by Roger Joseph Manning's friend Greg Hillegas. A laugh was had by all, and the conversation moved on. Somewhere on a legal pad in Roger or Andy's archives is that complete list...
After Pa-Pa-Pa-Pa-Puffy ended production in 2002, Puffy focused on performing in the United States. Several of their previous Japanese albums were released for the US market and they recorded theme songs for the animated series Teen Titans and SD Gundam Force. They have also done a cover version with Cyndi Lauper of her hit "Girls Just Wanna Have Fun". They were also interviewed on Jimmy Kimmel Live! by Jimmy Kimmel and performed their songs "Hi Hi" and "Akai Buranko" (Red Swing) on the show. They came back to the US in 2006 for their Splurge Tour. In April, 2017 the band made an appearance at Anime Boston for autograph signings. After their appearance at Boston Anime Convention they did a 3 city USA Tour which they called their "Not Lazy Tour" of the cities of San Francisco, Los Angeles, and Dallas, Texas.
