Shareholders

Shareholders of Nippon Steel Solutions Co., Ltd.
Five shareholders are currently on record for Nippon Steel Solutions 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 6.1% — the largest recorded stake — followed by Vanguard Tax Managed Fund-Vanguard Developed Markets Index Fund at 3.7%; 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.

Group Structure
Group structure of Nippon Steel Solutions Co., Ltd.
Nippon Steel Solutions Co., Ltd. sits 1 level below its ultimate parent, NIPPON STEEL CORPORATION, registered in Japan. 21 subsidiaries are recorded beneath it, across 8 jurisdictions. The full chain up to NIPPON STEEL CORPORATION is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Nippon Steel Solutions Co., Ltd.'s own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.

Those 21 subsidiaries span Japan, Dominican Republic, Thailand, United States, Singapore, Indonesia, and 2 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. Two of the 21 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
