SuMi TRUST Group holds the concept of diversity, equity & inclusion in the sense of "leveraging the diversity and creativity of each individual in management" as its Mission(management principles).

When the Group was formed in 2011, we set out three common aims: "Mission", "Vision" and "Value". The most important of these is the Mission (management principles).

We took the perspective of asking ourselves what our three stakeholders-our clients, society, and shareholders-demand of the Group, and added “offer a workplace where the diversity and creativity of its employees are more fully utilized to add value to the organization and where employees can have pride and be highly motivated in fulfilling their missions”, reflecting our thoughts on what kind of a company we want to be for the Group’s employees, as one pillar of our Mission. We have since then worked to make the creation of unique value through the interaction of diverse employees as part of our DNA.
