Daiichi Sankyo Company, Limited
Daiichi Sankyo Company, Limited is a registered legal entity registered in Japan, and its current status with National Tax Agency — Corporate Number Publication Site is active. Its registered address on file is Chuo, Japan. 5 shareholders are on record for Daiichi Sankyo Company, Limited, 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 of Daiichi Sankyo Company, Limited
Five shareholders are currently on record for Daiichi Sankyo Company, Limited, 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 STAR FUNDS-Vanguard Total International Stock Index Fund, holding 26% — the largest recorded stake — followed by VANGUARD SPECIALIZED FUNDS-Vanguard Health Care Fund at 23.5%; 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 18 subsidiaries span Japan, United States, Egypt, Hong Kong, Indonesia, China, and 6 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. Five of the 18 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
