His father was also a competitive swimmer so it is no wonder that for Yoshihiko Osaki, swimming is in his blood. He competed throughout high school but not until he went to college did he meet national success. Such success, that he was selected as a member of the 1960 Olympic team. After a disappointing second place finish to Bill Mulliken, Yoshihiko returned home a very determined man.
