Kiyokawa was born in Toyohashi, Aichi Prefecture, and graduated from the Tokyo College of Commerce (now Hitotsubashi University). Selected as a member of the Japanese swimming team at the 1932 Los Angeles Olympics, he won the gold medal in the 100 m backstroke event, with teammates Toshio Irie and Kentaro Kawatsu taking the silver and bronze. At the 1936 Berlin Olympics, he placed third in the same event.

Kiyokawa was critical of the large amounts of money being spent by both parties to entertain and influence the votes of the IOC members. He was also critical of the decision of the Japanese government to bow to political pressure from the United States to boycott the 1980 Summer Olympics in Moscow. Kiyokawa was the CEO of the general trading company Kanematsu Corp. from 1976. He died of pancreatic cancer on April 13, 1999.
