The current era is at a major turning point. The premises of corporate management are undergoing significant changes due to shifts in social and industrial structures, uncertainty in international affairs, and advancements in technology centered on AI. In Japan, we have entered a phase of fluctuating prices, wages, and interest rates, making it crucial for companies to address labor shortages and adapt to changes in industrial structure.

To further enhance Japan's competitiveness in this environment, it is essential to boost the growth potential of small and medium-sized enterprises, which account for a large proportion of domestic employment and support regional economies, supply chains, and industrial foundations.

Mizuho Bank has invested in UPSIDER*1 and welcomed the company into the Mizuho group to deliver more integrated and agile financial services to mid-sized and small businesses challenging themselves for business growth.
