First became interested in hiphop from the movie "Juice". Started DJing two years later in 1994 at age 16, and at 17 formed the short-lived group "Hannya" with MCs Rumi and Yoshi (now Hannya of Mousouzoku). Finding it difficult to enter battles or get club appearances with his "harsh" scratching style, he decided to focus on releasing mixtapes through which he could express his message. In 1999 he set up the Dis-Defense Disc label in order to release these mixtapes, and those of his friends Ske and Tatsuki, starting with the "Kaikoo With Scratch" tape for which he became famous.
He becomes more popular by the year in Japan, and has since released "Kaikoo DVD", a documentary on underground Japanese hiphop, organised a series of "Kaikoo" events, and in 2006 released his first album "Spin Heddz" on the label Pop Group. His new album "DHARMA DANCE" comes out on April 5, 2008 from Pop Group.
