Shareholders
5
Shareholders of Japan Steel Works Co., Ltd.
Five shareholders are currently on record for Japan Steel Works 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 9.3% — the largest recorded stake — followed by Global X Fds-Global X Lithium & Battery Tech ETF at 7.9%; 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.

Data availability
Those 31 subsidiaries span Japan, South Korea, China, India, United States, Hong Kong, and 4 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 31 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
