Onoken is a musician who makes his music electronically and frequently uses the electric organ to produce solidable tunes. A resident of Tokyo, Japan, Onoken speaks both Japanese and English, but apparently prefers Japanese. Recently, he took up Korean as his third language, hoping to enter the Korean market. Onoken's works are quite diverse, ranging from goa trance to Digital hardcore. Most Onoken songs have a BPM divisible by 10, but this is not always the case.

Onoken did the music for the sci-fi mystery game "I/O" for the PlayStation 2. The game was only released in Japan.
