Eisaku Satō
As intensive work took place during 1966 to prepare for the opening of the new bank in Manila, high on the agenda was choice of president. Japanese Prime Minister Eisaku Satō asked Watanabe to be a candidate. Although he initially declined, pressure came from other countries and Watanabe agreed. In the absence of any other candidates, Watanabe was elected first President of the Asian Development Bank at its Inaugural Meeting on 24 November 1966.
