Grievance Mechanism and Stakeholder Dialogues

We have established a number of consultation systems for our employees and will continuously work on establishing appropriate mechanisms to ensure people have access to remedy when needed. Employees, customers, and other stakeholders can bring to our attention their concerns through our branches, head office, call centers, designated telephone lines, and via our website.

We place emphasis on engagement with our stakeholders and strives for transparency and responsiveness.


Mizuho has a grievance mechanism through our branches and headquarters. Mizuho Bank, Mizuho Trust and Banking, Mizuho Securities have designated telephone lines shown on website. Mizuho Americas also has its own grievance system on website to receive comments from stakeholders.
