He was born and raised in Los Angeles, California, to two Japanese immigrants.[1] It was not until middle school that he became interested in music and that eventually led him to start his musical career in 2007.[1] He was accepted to UCLA and UC Berkeley but had chosen music. Inoue performs every instrument on his recordings in addition to writing and composing the pieces on his own. He claims to have learned Japanese by reading manga and watching anime.
He gained prominence when his song "Closer" was used as the fourth opening theme for Naruto: Shippuden.[2] His fifth single "Kaze no Gotoku" was used as the second theme song for the Yorinuki Gin Tama-san anime.[3]
Inoue contributed to Tetsuya's 2011 solo album Come On! by rapping on the track "Eden"[4] and later wrote and was featured on Totalfat's 2011 single "World of Glory".[5]
