Katsumi Komiyama: Boxing Career and Notable Fights
Katsumi Komiyama was a Japanese professional boxer who competed in the light-flyweight division. His career included domestic bouts in Japan, appearances in the United States and a WBA world-title challenge against South Korea’s Yoo Myung-woo in February 1989.
From early bouts to longer contests
The Sport & Note record lists a four-round draw with Makisuke Nishimura in Osaka on February 12, 1985. Komiyama won their rematch that June and added victories over Hideaki Suda and Eiji Moriya during the same year. By September, he was competing over six rounds against Tatsuya Yamada.
His schedule became more demanding in 1986. He defeated Missile Kudo over ten rounds in September before losing a ten-round decision to Tomohiro Kiyuna in Tokyo that November. In 1987, he drew with Hiroyuki Miyata and lost their return bout, then traveled to Long Beach, California, for two victories over Rogelio Martinez.
The 1989 world-title challenge
Komiyama challenged Yoo for the WBA junior-flyweight championship on February 12, 1989. Yoo retained the title by tenth-round stoppage. The bout remains the most prominent international championship appearance in Komiyama’s record.
His career continued afterward. Boxerlist’s bout history records wins over Toshinari Miyazato in April 1989 and Tsuyoshi Niibori in July, both in Osaka. Those results show that the unsuccessful world-title bid was followed by further competition at home. Taken together, his schedule traces the progression from four-round domestic contests to longer-distance fights and an opportunity at world level.

Further career results
Komiyama’s record includes international appearances outside his Japanese base. He defeated Rogelio Martínez by unanimous decision in Long Beach in November 1987 and drew with Tony DeLuca in San Diego in February 1988. Back in Japan, he drew with Roger de Rama in Osaka in October 1988. Those results preceded his February 1989 challenge against Myung-Woo Yuh in South Korea and show that his career already included bouts in multiple countries before the world-title attempt.
