Henry K. Okamura had been a judo champion for much of his life when a stroke felled him in 1993. After a life of activity that earned him the highest-ranking judo black belt in the United States – and the presidency of the Chicago Judo Black Belt Association for 30 years – his sudden idleness hit him hard. “After the stroke he had a difficult time,” said his wife of 52 years, Mitsuko. “He couldn’t walk at all. For 12 years I took care of him. It was difficult for me, but everything is in your attitude and he felt the same way.”
