Satoru Sayama
Shunji Kosugi made his debut on January 11, 1981 against Norio Honaga. He was known for his technical prowess in the ring, influenced by Karl Gotch. He was the last man to defeat Satoru Sayama, before Sayama became Tiger Mask and also the very first opponent of the future Jushin Thunder Liger, Keiichi Yamada. Kosugi's biggest accomplishment came in April 1985, when he defeated Yamada to win the very first Young Lion Cup.
