Tsunao Okumura (奥村 綱雄, Okumura Tsunao) (5 March 1903 – 7 November 1972) was the president of Nomura Securities from 1948 to 1959. He served as the King of Japanese stockbroking in the 1950s. Born as the son of a wealthy confectioner, Okumura exhibited little ambition early in life. At the age of nineteen, he enrolled in Kyoto University where he enjoyed the luxuries afforded to a privileged student as such. His father granted him a monthly allowance of 100 Yen, a substantial sum in an era where twenty yen could provide a comfortable lifestyle. Preferring leisure over academics pursuits, he dedicated much of his time frequenting Kyoto's dance halls, with his affluent peers. Despite graduating with mediocre grades and facing initial rejection from banks such as Mitsubishi, Mitsui, and Yamaguchi, Okumura secured a position in Nomura's research department through personal connections.
