Kazuhiko Katō became a radio show presenter and a television personality in Japan. He had a successful solo career after the Sadistic Mika Band broke up; pursuing a ska direction before acquiring interest in European experimental music. Most of his solo work employed the talents of the other former Sadistic Mika Band members and other notable guest artists such as Ryuichi Sakamoto, Haruomi Hosono and Akiko Yano. He released two acoustic albums with Kōnosuke Sakazaki of The Alfee under the name Kazukoh in 2007 ("Golden Hits") and 2009 ("Happy End"), and found time to form a new band called Vitamin-Q in 2008, releasing one album ("VITAMIN-Q feat ANZA"). Katō committed suicide by hanging on October 17, 2009 in the Kitasaku District of Karuizawa in Nagano Prefecture, Japan.
