As Tadashi Sakai's chief mechanic, he was in charge of machines such as the Fuji GC, and in 1981 he took over Sakai Engineering and established Cerumo. The company name is derived from the Italian word for steady. While operating as a maintenance garage, then formed the team in 1991. Since then, he has competed in SUPER GT (formerly All Japan GT Championship JGTC) and Formula Nippon then the current Super Formula.
