Announced in 1999, Mizuho Financial Group was established on April 1, 2002 by the merger of Dai-Ichi Kangyo Bank, Fuji Bank and the Industrial Bank of Japan. All three predecessors were major financial institutions in their own right and had served as cornerstones of major zaibatsu (prewar era) and keiretsu (postwar era). In April 2002, Mizuho Corporate Bank and Mizuho Bank were established as two core banking subsidiaries of Mizuho Financial Group through a split and merger process reorganizing the three legacy banks. It was the first financial holding company structure created among major Japanese banks. Mizuho Corporate Bank focused on large corporations, financial institutions and public sector entities in Japan and overseas. Mizuho Bank focused on individuals and small and medium-sized companies in Japan.
