And in the 70s, boxing was the most popular sport in Korea. And historically, the sport with the most Korea-Japan matches is boxing. Since the 1970s, boxing matches have always been accompanied by Korea-Japan matches. Japan has always looked down on Korea's hungry boxers. And they've been embarrassed like this many times. In 1975, middleweight challenger Yoo Je-doo challenged Japan's boxing hero and world champion Koichi Wajima, and won by KO in Japanese territory, becoming Korea's third world champion after Kim Ki-soo and Hong Soo-hwan. Because he defeated the Japanese fighter so thoroughly in Japanese territory, he became a national star in Korea. At the time, President Park Chung-hee gave him 3 million won as a gift, 1 million won of which he donated to the defense fund, 1 million won to help the underprivileged, and the remaining 1 million won was split 300,000 won each with his manager and trainer. And the mayor at the time was planning to donate 500 pyeong in Yeongdong, Gangnam, but he requested land in Yeouido instead of Yeongdong and received it converted to 100 pyeong. He had to fight in Japan for the second defense as well, against Koichi Wajima, who had lost the title to Yoo Je-doo. Yoo Je-doo's manager informed him that he would defend the title in Korea, but the contract stipulated that the second defense must be held in Japan when he challenged for the world title, and if he broke it early, he would have to pay a penalty of 150,000 dollars, so Yoo Je-doo had no choice but to go to Japan again at a disadvantage. However, something strange happened during this match. Yoo Je-doo staggered around like he was drunk and felt lethargic, and later rumors and suspicions arose that Yoo Je-doo had been involved in a drug scandal. It was the Park Chung-hee regime at the time. It was a time when you could be disadvantaged depending on your political stance. It was said that the Central Intelligence Agency, which knew of his close relationship with DJ, put drugs in his food to make Yoo Je-doo fail. Due to the circumstances, it was difficult to grasp the truth of the incident, and Yoo Je-du lost the title to the money power of Japan without having a single title match in Korea. Ryu Je-du's total matches are 55 matches, 50 wins, 2 draws, and 3 losses. Of these, 38 were matches against foreign players, 30 were matches against Japanese players, and out of the 30 matches, he won 28, 1 draw, and 1 loss. The 1980s were the golden age of Korean professional boxing. Even now, many geniuses in boxing and martial arts emerge in Japan. However, the Japanese boxing geniuses who emerged in the 80s were often embarrassed by hungry Korean boxers. In the 1980s, we take a look at the world title matches between Japan's boxing geniuses and Korean professional boxers. As of 2015, only four Asian boxers have been inducted into the Boxing Hall of Fame. Two of them are Korean: Jang Jung-gu (WBC 15 defenses) and Yoo Myung-woo (WBA 17 defenses). Jang Jung-gu is said to have been the first Korean to be included in the 100 Greatest Boxers of the 20th Century. At the age of 20, Jang Jung-gu defeated Ilario Zapata in March 1983 to become the WBC Light Flyweight World Champion. Since then, many of Jang Jung-gu's world title matches have featured Japanese boxers. He was a Japanese boxer from the first defense, and defeated Masaharu Inami by KO in the second round. In August 1984, his opponent in the fourth defense was Katsuo Tokashiki of Japan. This fighter became famous as a Korean boxer killer after winning the world title against Kim Hwan-jin of Korea and defending the title against Korean boxer Kim Sung-nam and then Kim Hwan-jin. Jang Jeong-gu had to fight an extreme defense match against a Japanese fighter during the Liberation Day season, but he had difficulty losing 13 kg for the weigh-in due to his failure to control his weight due to his usual food urges. He entered the match with great physical problems, as he succeeded in losing weight despite showing signs of exhaustion and barely passed the weigh-in. As the match began, Tokasaki, who had speed and quick feet, attacked Jang Jeong-gu from the beginning, and Jang Jeong-gu, who was struggling due to the aftereffects of losing weight, defeated Tokasaki by KO with his tenacious spirit. His opponent for the 5th defense m
