Mark Lewin
With Rikidōzan's murder in 1963 Ohki returned to his homeland to raise the profile of professional wrestling there, but returned to the JWA when Toyonobori and Inoki left the promotion, though he returned the next year. Also in 1967 Ohki became the top star in Korea with his defeat of Mark Lewin to win the Worldwide Wrestling Associates World Heavyweight Championship. With this the JWA wanted to rename him to Rikidōzan but the plan never went through.
