Shin-Etsu Polymer Co., Ltd.
Shin-Etsu Polymer Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 4010001034802, 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 Chiyoda Ward, Japan. 5 shareholders are on record for Shin-Etsu Polymer 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 Shin-Etsu Polymer Co., Ltd.
Five shareholders are currently on record for Shin-Etsu Polymer 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 Vanguard International Stock Index-Total Intl Stock Indx, holding 11.8% — the largest recorded stake — followed by DFA Japanese Small Company Series at 7%; 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 8 subsidiaries span Japan, Indonesia, China, Singapore, United States, Taiwan, 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. One of the 8 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
