Sanyo Special Steel Co., Ltd.
Sanyo Special Steel Co., Ltd. is a registered legal entity registered in Japan, and its current status with National Tax Agency — Corporate Number Publication Site is active. Its registered address on file is Himeji, Japan. 5 shareholders are on record for Sanyo Special Steel Co., Ltd., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from National Tax Agency — Corporate Number Publication Site and was last updated on 1 October 2026.

Shareholders of Sanyo Special Steel Co., Ltd.
Five shareholders are currently on record for Sanyo Special Steel 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 STAR FUNDS-Vanguard Total International Stock Index Fund, holding 23.1% — the largest recorded stake — followed by DFA INVESTMENT DIMENSIONS GROUP INC-DFA Intl SMALL CAP VALUE PORT. at 16.8%; the remaining 3 shareholders shown hold smaller stakes.
