Shareholders of Sankyo Tateyama Co., Ltd.
Five shareholders are currently on record for Sankyo Tateyama 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 DFA International Small Cap Value Portfolio, holding 24% — the largest recorded stake — followed by Vanguard International Stock Index-Total Intl Stock Indx at 22.8%; 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 25 subsidiaries span Japan, China, Belgium, Singapore 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. Three of the 25 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
