Yoshio Utsumi (内海 善雄 Utsumi Yoshio, born August 14, 1942) was the secretary-general of the International Telecommunication Union, 1998-2006.
He was born in Japan in 1942, and earned his Bachelor in law at the University of Tokyo, and a Master of Arts in Political Science from the University of Chicago.
He has worked for the Japanese ministry of post and telecommunication in various high level posts, including helping liberalize Japan's telecommunications market, serving as director-general of the ministry, and serving as first secretary of the Japanese mission to the ITU for 3 years, before he moved to the post of ITU secretary-general in 1998.
He was reelected in 2002 for a second term, but was not a candidate for reelection in 2006, since the rules of the ITU do not permit more than 2 consecutive periods as secretary-general.
