WCRC Researched Brand · World's Most Powerful Brands 2026 · Second Global Mega Edition

Mizuho Financial Group

Mizuho Financial Group is one of Japan's three megabanks, with a large global corporate and investment banking business that includes its acquisition of Greenhill. It is a Japanese financial holding company with A-range credit ratings and profits that are rising as Japanese interest rates normalise. WCRC's research found its strongest dimension was financial health, followed by industry standing as a megabank. Coverage is mostly domestic and financial, and it has a domestic retail brand and a domestic digital presence. In 2021 a series of system failures led to business-improvement orders from the Financial Services Agency.
