Sumitomo Mitsui Trust Group Business Description

Address 1-4-1 Marunouchi, Chiyoda-ku, Tokyo, JPN, 100-8233
Sumitomo Mitsui Trust Group is the fifth-largest Japanese bank by assets and revenue. It is the only remaining stand-alone trust bank after the late 1990s deregulation removed legal barriers between commercial banking and trust functions in Japan; its former rivals in trust banking merged and became units of Mitsubishi UFJ FG and Mizuho. It has no capital ties with Sumitomo Mitsui FG, despite the similar name and common ties to Sumitomo and Mitsui group companies. In fiduciary services, SMTG is the market leader in Japan in total assets under custody. It is the largest manager of corporate pension funds and trails only Nomura in investment trusts.
