In 1948, Kiyokawa became a director of the Japan Swimming Federation, and a member of the International Olympic Committee from 1975-1989, serving as Vice Chairman from 1979-1983. During his tenure, the city of Nagoya made a strong bid for the 1988 Summer Olympics, competing against Seoul, South Korea. Kiyokawa was critical of the large amounts of money being spent by both parties to entertain and influence the votes of the IOC members by both parties. 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 also the CEO of the general trading company Kanematsu Corp. from 1976. He died in 1999 due to Pancreatic cancer.
