Shareholders of Hamamatsu Photonics Co., Ltd.
Four shareholders are currently on record for Hamamatsu Photonics 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 TAX-MANAGED FUNDS-Vanguard Developed Markets Index Fund, holding 11.6% — the largest recorded stake — followed by iShares Trust-iShares Core MSCI EAFE ETF at 8.8%; the remaining 2 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 12 subsidiaries span Japan, Taiwan, South Korea, Belgium, United States, China, 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. Five of the 12 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
