Chage and Aska (チャゲ & 飛鳥, Chage and Asuka?) or Chage and Asuka, are a Japanese popular music duo composed of two singer-songwriters from Fukuoka Prefecture, Chage (b.1958) and Ryo Aska (飛鳥 涼, Asuka ryo?) (b. 1958). To date they have sold over 31 million albums and singles in Japan.
They were formed in the late 1970s at the suggestion of A&R of the Yamaha Music Foundation. After the hit single "Banri no Kawa" in 1980, they produced several smash hits irregularly throughout the 1980s. However, thanks to Aska's hit solo single "Hajimari wa Itsumo Ame" in 1991, and several powerful tieups with TV programs, their popularity peaked during the first half of the 1990s. In those days, they released five million-selling hits: "Yah Yah Yah", "If", "Heart", "Meguriai", and their most well-known "Say Yes". "Say Yes", released in 1991, is the sixth best-selling single in Japan.
They attempted to spread their market worldwide, especially to the United States. Yamaha released a compilation of cover versions by Western artists (Maxi Priest featuring Shaggy, Lisa Stansfield, Chaka Khan, Michael Hutchence, Alejandro Sanz, Cathy Dennis, Apache Indian, Boy George, Richard Marx, Londonbeat, Marianne Faithfull, and Wendy Matthews)
