Corporate & Investment Banking Company


In order to further strengthen our ability to meet the increasingly diverse and complex needs of our clients, we established the new Corporate & Investment Banking Company by integrating the Corporate & Institutional Company with the investment banking functions of the Global Products Unit. Increasing public interest in sustainability and other social issues is accelerating various structural shifts. By resolving social issues and supporting clients to enhance their corporate value, we will contribute to the sustainable growth and prosperity of industry, the economy, and society as a whole.

Business overview

*Materiality areas:

  • Industry development and innovation
  • Sound economic growth
  • Environment and society


  • Capacity to co-create value with clients through sector coverage structure, aligned among banking, trust banking, and securities
  • Merged organization of sector coverage and product line to enhance capability to connect various functions within the Mizuho group and provide both financial and non-financial solutions
  • Ability to provide sound risk capital for co-creating value with clients

By integrating coverage and products following the establishment of the new in-house company, we will ensure "market-in" approaches to clients (i.e., approaches informed by client needs), thereby enhancing our ability to provide solutions.
