Mitsui-Soko Holdings Co., Ltd.
Mitsui-Soko Holdings Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 2010401046416, and its current status with National Tax Agency — Corporate Number Publication Site is active. The company was incorporated on 5 October 2015 and lists its registered address as Chuo Ward, Japan. 5 shareholders are on record for Mitsui-Soko Holdings Co., Ltd., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.

Shareholders

Shareholders of Mitsui-Soko Holdings Co., Ltd.
Five shareholders are currently on record for Mitsui-Soko Holdings Co., Ltd., reflecting the kabunushi meibo (shareholder register) maintained under Articles 121-122 of the Companies Act rather than a public filing. The largest of these is Avantis International Small Cap Value ETF, holding 6.8% — the largest recorded stake — followed by DFA Japanese Small Company Series at 5.1%; the remaining 3 shareholders shown hold smaller stakes. Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Those 16 subsidiaries span Japan, Singapore, United States, China, Indonesia, Vietnam, and 1 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. Eight of the 16 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
