Aoki was born in 1957 in Tokyo, Japan into an artisan family called TOYOAKI MOTO, traditionally categorized as OKIYA, meaning a booking and training agent for Geisha ladies in downtown Tokyo's designated area. While the economy and social environment forced many of those traditional artisan family business to close down in the 60's , Aoki was luckily able to receive some of the important essence of traditional Tokyo Geisha cultural training and studies at age 4, and became a part of the performing crew in early childhood. After his grand mother passed away, he had kept the Tokyo music training until early teen, and shifted his musical focus to American pop music and experimental music.
