A culture where diverse strengths resonate with one another is the driving force behind “Trust for a flourishing future.” Sumitomo Mitsui Trust Group, Inc. President & CEO Kazuya Oyama

Top Message

At Sumitomo Mitsui Trust Group, our stated mission includes a call “to leverage the diverse backgrounds and creative potential of our personnel in our management practices.”

To maintain the trust of our customers, society, and shareholders—and to be a partner with whom they can entrust their hopes for the future—it is essential for us to create an environment where diverse strengths can be utilized.

Meeting the expectations entrusted to us and connecting them to the future—this is our responsibility as a trust bank—and creating a culture where diverse individual strengths can flourish is a crucial theme that we must continue to address.

Different perspectives and experiences remind us that what was once considered the norm is not the only way. But diversity alone does not generate value. It is only when individuality is respected, when people can exchange opinions without hesitation, and when mutual inspiration occurs that new value and innovation can be created.

This dynamic interplay is the very source of our Group’s DNA—the creation of new value through diverse strengths.

We will further strengthen our initiatives for Diversity, Equity & Inclusion (DE&I) to ensure that the value created from diversity is reliably passed on to society, to our clients, and into the next 100 years.
