Naoyuki Sato (born November 19, 1975) is a BEMANI artist who made his debut in 2004 on pop'n music 10 CS with Beyond The Earth. After a few years of writing various CS songs for IIDX and pop'n music, he started writing songs for the arcade versions too, and is now one of the most wide-spread BEMANI artists, writing songs for every BEMANI series out there right now. His music ranges from "worldly" music, drum and bass, and some light J-POP.
Recent interviews have confirmed that Naoyuki will be sound directing beatmania IIDX 20 tricoro alongside Toshiyuki Kakuta (L.E.D.), his first sound directing job in a BEMANI game.
