Process for Identifying Key Sustainability Areas

When designating materiality areas at Mizuho, we consider (i) expectations of society,1 and (ii) importance for Mizuho.We reorganized the materiality areas designated in our 5–Year Business Plan based on a new assessment of the expectations of society and importance for Mizuho. We are setting opportunities to revise materiality areas on a yearly basis.

  1. Expectations and requirements various stakeholders maintain towards financial institutions in general, and towards Mizuho specifically, in regard to the sustainable development of the economy, industry, and society
  2. Medium– to long–term impact on our corporate value and compatibility with Mizuho's strategies and business areas
