Yoshisada Yonezuka (米塚 義定, Yonezuka Yoshisada^?, May 19, 1937 – October 18, 2014), was a Judo instructor and two time U.S. Olympic Judo Team coach.

A bone marrow drive was attempted to no avail.

After defeating nine 2nd degree blackbelts in succession at the Kodokan, he received a special promotion to 3rd degree black belt. He also began studying Shorinji Kempo and several styles of karate including wado ryu, and shito-ryu.

In 1959, he was a member of the university team winning the team championship. The following year he graduated Nihon University majoring in business. Following his childhood dream he went to the United States and began teaching judo at West Point Military Academy. In 1960 he moved to the United States.

Yonezuka was twice chosen to serve as head coach of the United States at the Olympics Judo Team, and he coached three U.S. World Judo Championships Teams as well.
