Ōkubo began study at the University of Tokyo in 1949 and received his bachelor"s degree there in 1952. Afterwards, he was a postdoc in 1959/60 at the University of Naples, in 1960/61 at European Organization of Nuclear Research, and then in 1962 began researching again at the University of Rochester, where he became a professor in 1964 and retired in 1996 as an emeritus professor Ōkubo works primarily on elementary particle physics.
In 1966 he was a Guggenheim Fellow and in 1969 a Ford Fellow.
He is famous for the Gell-Mann-Okubo mass formula for mesons and baryons in the quark model. This formula correctly predicts the relations of masses of the members of SU(3) multiplets in terms of hypercharge and isotopic spin. He is a member of the American Physical Society and the American Mathematical Society.
