Group Structure
Sumitomo Mitsui Trust Bank, Ltd. sits 1 level below its ultimate parent, SUMITOMO MITSUI TRUST GROUP, INC., registered in Japan. 27 subsidiaries are recorded beneath it, across 8 jurisdictions. The full chain up to SUMITOMO MITSUI TRUST GROUP, INC. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Sumitomo Mitsui Trust Bank, Ltd.'s own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 27 subsidiaries span Japan, Cayman Islands, United Kingdom, China, Hong Kong, United States, and 2 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. One of the 27 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
