Hideki Naganuma is a Japanese music composer who primarily does work for video game soundtracks. His music is broadly defined as J-Pop, but can be quite hard to categorize. He is skilled at mixing Japanese techno, funk, soul, and hip-hop elements to create a unique and vivid sound. Naganuma is most famous for his original compositions used in the Sega Dreamcast game (Jet Grind Radio in the USA) and Jet Set Radio Future. In 2004 he authored most of the music for the arcade skating game Ollie King.
