Mizuho Financial Group is roughly tied with megabank peer Sumitomo Mitsui Financial Group for the status as Japan's second-largest bank after Mitsubishi UFJ Financial Group. In Japan, Mizuho has more of a corporate focus than SMFG, which has a larger retail business. Its overseas weighting is slightly smaller than that of MUFG. Unlike its two Japanese megabank peers, which own foreign banks outright or hold noncontrolling stakes in local banks overseas, Mizuho expanded in recent years beyond its traditional Japanese borrowers, mainly through its core banking and securities units, focusing on the financing needs of global multinational corporations.
