Cho was born in Pohang, Korea, on 13 October 1940, during the period of Japanese occupation. He was the eldest of three brothers. He began training in the martial arts when he was around 10 years old. In an interview, he commented on his childhood in Pohang, Korea: "Although they were not really gang members, young people used to roam from town to town and beat up kids and take away their toys. One time, I was beaten up by some boys around 12 or 13 years old. At the time I thought it was pretty bad, so I wanted to protect myself." Cho attained the rank of 1st dan black belt by the age of 13, and had reached 4th dan by the age of 21. In addition to taekwondo, he also trained in boxing for two years.
