Since its establishment in 1877, Hokuriku Bank has developed an extensive network of branches throughout the Hokuriku district. On account of trade through the Kitamae-bune or "Northbound Ships," branches extended to the major cities of Hokkaido, enabling the bank to meet customers' needs. The Hokkaido Bank, which was established in 1951, has developed a network of branches throughout Hokkaido, and built a firm business structure centered on individuals and small and medium-sized enterprises.

The Hokuriku Bank, Ltd. and The Hokkaido Bank, Ltd. underwent management integration in September 2004 to form the Hokuhoku Financial Group Inc., which today operates a super-regional financial network that encompasses the Hokuriku region, Hokkaido, and Japan's three major metropolitan areas (Tokyo, Osaka, and Nagoya areas).
