Nomura Holdings Inc. said Friday it has decided to appoint its executive vice president, Nobuyuki Koga, as president of the firm.

Koga will replace Junichi Ujiie, who will in turn become the holding firm's chairman. The new appointments will take effect April 1.

The holding company also said that it and its group firms will adopt a U.S.-style structure designed to bolster corporate governance and boost management transparency and efficiency. Under the new structure, which will be made possible by the planned revision of the Commercial Code on April 1, Nomura will separate operating officers from directors and create three independent committees on its board.
