Shareholders of Okamoto Machine Tool Manufacturing Co., Ltd.
Five shareholders are currently on record for Okamoto Machine Tool Manufacturing 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 Core Equity Portfolio, holding 23.5% — the largest recorded stake — followed by iShares International Small-Cap Equity Factor ETF at 21.4%; 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 9 subsidiaries span Japan, Thailand, United States, Germany, Singapore, India 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 9 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
