## Company history

The group traces its roots to Japan’s trust-banking industry: Mitsui Trust was founded in 1924, and the institution that became Sumitomo Mitsui Trust Bank was established in 1925. Mitsui Trust and Chuo Trust merged in 2000 to form Chuo Mitsui Trust & Banking. [26](https://www.smtg.jp/english/company/history/)[27](https://app.finbar.com/go?id=P139750485)

In 2011, the Sumitomo Trust and Chuo Mitsui groups integrated under a common holding company. Their trust banks were consolidated into Sumitomo Mitsui Trust Bank in 2012. The holding company later adopted the name Sumitomo Mitsui Trust Group, Inc. [26](https://www.smtg.jp/english/company/history/)[17](https://app.finbar.com/go?id=P139748586)
