Kim Tae-sik (February 24, 1929 – October 26, 2006) was a South Korean professional wrestler and ssireum player, better known by the ring names Kintarō Ōki (Japanese: 大木金太郎) and Kim Il (Korean: 김일; Hanja: 金一).

[3] Kim was originally a Ssireum player, but he had hopes of becoming a student of fellow Korean wrestler Rikidōzan, who had emigrated to Japan in 1940.

In 1964 and 1965 he went to Texas, where he competed for Big Time Wrestling in Dallas as "Kintarō Ōki" and for Dory Funk's Western States Sports promotion in Amarillo as "Tetsurō Sato".

In 1964, Ōki faced NWA World Heavyweight Champion Lou Thesz in what turned into a legitimate shoot contest.

In 1967, Ōki became the top star in Korea with his defeat of Mark Lewin to win the Worldwide Wrestling Associates World Heavyweight Championship.

[4] Following then Ōki did not compete much, with his official retirement card on April 2, 1995, held at a Weekly Pro-Wrestling magazine sponsored show at the Tokyo Dome in Japan.
