Mitsubishi UFJ Financial Group Inc.'s main lending unit is eyeing further acquisitions in the U.S. and Asia as part of its long-standing aspirations to become one of the world's leading commercial banks, the unit's new president said.

The U.S. banking market remains a focus because of its size and steady growth, while Asia presents opportunities because of the expanding middle class, Takashi Oyamada, president and chief executive officer of Bank of Tokyo-Mitsubishi UFJ Ltd., said in an interview at the lender's headquarters last week.

Oyamada, 60, became the bank's new president on Friday.
