Korean fighter Ju Do Chun (20-4-3, 11) is not someone that many fans will be familiar with, though he is certainly more than just a foot note in the history of professional boxing. In fact he was one of the first ever Super Flyweight world champions, and was the inaugural IBF champion at the weight, winning the title in 1983. His reign wasn't the best, but with 5 defenses he set the mark to beat. It was, in fact, a record that stood for decades, with no one managing more defenses until Jerwin Ancajas more than 30 years later.
Sadly Chun failed to face the best of his era. Potential bouts between the Korean and the likes of Jiro Watanabe and Khaosai Galaxy, Rafael Orono and Payao Poontarat wouldn't had ended well for him. Despite that he left his mark on the division, and really did play a major role in the division in South Korea.
Sadly Chun's career was a relatively short one, running from 1981 to 1989. Despite that he scored a number of notable wins, and we'll have a look at those now, as we bring you the 5 most significant wins for... Ju Do Chun.
Young Kil Choi II (May 14th 1983)
We start this very early in Chun's career. In his second professional bout, on May 10th 1981, Chun suffered his first loss, losing a decision to Young Kil Choi. That sparked a rivalry between the two men who would clash twice more, in 1983. In their second bout Chun got to avenge his loss to Choi, taking an 8 round points win over his countryman to even the score. This was certainly not a massive win for Choi, especially given what would later come, but was a significant victory over the only man who would beat him during the early part of his career. In fact the loss to Choi was Chun's only defeat until 1985, after he had won the IBF Super Flyweight title.
Chun would also go on to win the rubber bout between the men, stopping Choi in the 9th round, later in 1983.
Hee-Yun Jung (June 26th 1983)
Just months after Chun avenged his first loss he claimed his first silverware, the Korean Super Flyweight title. He did that by stopping reigning champion Hee Yun Jung, who was looking to record his second defense of the title.
Jung had won the belt in 1982, when he defeated Ok Kyun Yuh, and made his first defense in early 1983. He then scored a non-title win, beating future Chun opponent Diego De Villa, before facing Chun himself. Chun wasn't in the mood to let his countryman shine, and instead Chun ended up taking Jung out in 4 rounds to claim the Korean title and take a huge step towards his first world title title bout.
Like many wins in this series this was a victory that aged well. In the years that followed Jung claimed a Korean title at Super Bantamweight and then won the OPBF Super Bantamweight title, which he defended 4 times. Jung would also never suffer another stoppage. This win genuinely does need to be regarded a lot higher than many of Chun's other wins.
Ken Kasugai (December 10th 1983)
After winning the Korean title Chun defended the belt twice before getting on the road for his first bout on foreign soil. That just so happened to be in Japan, against Ken Kasugai, for the newly created IBF Super Flyweight title. Coming in to thus Chun was just 19 years old, he was 13-1-3 (4) as a fighter but had done little to really earn a world title fight. On the other hand Kasugai was 27 years old but had been out of the ring for a while and certainly wasn't one of the leading Super Flyweights. It was more a chance for the IBF to get a foothold in Asia, which they were attempting at the time.
Despite being just a teenage Chun was too good for Kasugai, and the Korea stopped the Japanese local in 5 rounds to claim the world title, and make his mark on the sport. This was, in many ways, the defining victory of Chun's career and the one that put him in line for some much bigger bouts. Sadly the win really didn't age well, with Kasugai never fighting again after this bout.
Prayurasak Muangsurin (January 28th 1984)
Sadly for Chun his reign was packed with poor challengers, who had done little and went on to do little. The one exception to that was actually his first defense which came against Thailand's Prayurasak Muangsurin, a name that some hardcore fans from the era will be familiar with. And with good reason.
Prayurasak Muangsurin was a genuinely talented fighter who had won 12 of his first 13, including a notable win over former WBC Super Flyweight champion Chul Ho Kim, in South Korea. He had also won the Thai Super Flyweight title, and, later in his career, win the OPBF Super Bantamweight title, and challenge for a world title at 122lbs. His record might not be packed with big names, but Prayurasak Muangsurin is, or rather was, a very good fighter back in the 1980's. Sadly for him he ran into Chun who was looking to prove a point, and Chun stopped him in 12 rounds to retain the IBF world title. Sadly following this win Chun's challengers got incredibly poor, such as Diego De Villa and Felix Marquez, fighters who wouldn't have stood a chance on the regional scene now a days.
William Develos (July 22nd 1984)
Although Chun's challengers were poor we do need to find a fifth win of note for him, and with that in mind the one challenger, outside of Prayurasak Muangsurin, worthy of some note was Filipino fighter William Develos.
Develos wasn't a big name but he was an accomplished professional, not something we could say about Chun's typical challengers. Develos was a former OPBF Super Flyweight champion who had beaten Yung-Shik Kim for the title, and had also fought to a draw with Bobby Berna, held a win over future world champion Frank Cedeno, had been very competitive with the often under-rated Eijiro Murata and had beaten former world title challenger Suk Chul Bae. Basically he wasn't a world class fighter, but was a very solid regional level contender. The type of fighter that Chun should have been facing, instead of Diego De Villa, Felix Marquez and Kwang Koo Park.
Despite Develos being a solid fighter he was stopped in 7 rounds by Chun, who recorded his 4th defense of the IBF title. Sadly for Develos this loss was the start of the end for him, and he would go 5-4 after this, suffering 3 more stoppage losses, before retiring in the 1980's.
As for Chun, his reign came to an end less than a year after this win and did so in an historic manner. The Korean was stopped in 8 rounds by Elly Pical in Jakarta, with Pical becoming the first ever Indonesian world champion thanks to this win. That win began Pical's rise to stardom at home, and was a sad ending for Chun's reign. In fact it was the start of the end for Chun, who lost again in his next bout. He then vanished from the ring for 3 years before going 1-1 in a short lived comeback, before retiring for good.
