How Mizuho Bank champions SMEs across Japan’s financial landscape

Mizuho Bank, part of the Mizuho Financial Group, is one of Japan’s “big three” commercial banks and a cornerstone of the nation’s financial system. With roots tracing back to the late 19th century, Mizuho today operates an extensive network of over 500 domestic branches and serves millions of retail and corporate clients across all 47 prefectures in Japan. It is also a global institution, offering full-service banking in around 40 countries.

A significant and strategically important segment of Mizuho’s client base is small and medium-sized enterprises (SMEs). In Japan, SMEs represent the backbone of the economy — numbering in the hundreds of thousands and providing a substantial share of employment and regional economic activity. Mizuho supports this sector through a broad range of financial products, including loans, working capital financing, and advisory services tailored to smaller corporations’ needs. The bank’s presence across the country enables it to nurture relationships with local companies that often lack access to alternative sources of capital. 

According to Japan’s main bank surveys, Mizuho remains a trusted financial partner for tens of thousands of companies across Japan, reflecting the importance of SME relationships in the country’s commercial banking landscape.
