Seiji Sakaguchi
Kazuo Sakurada debuted on June 21, 1971, in the old Japan Pro Wrestling Alliance against Kim Duk. On March 8, 1973, he became involved in a shoot when his mid-card match against rookie Tsutomu Oshiro went horribly wrong and Sakurada began beating Oshiro severely, knocking him out of the ring. Oshiro was going to jump to New Japan Pro-Wrestling along with his mentor Seiji Sakaguchi and friend Kengo Kimura, and Sakurada took actions into his own hands, blaming them for jumping ship. When the JPWA closed in April 1973 Sakurada joined All Japan Pro Wrestling.
