GSI Creos Co., Ltd.
GSI Creos Co., Ltd. is a registered legal entity registered in Japan under 3010001008666, and its current status with National Tax Agency — Corporate Number Publication Site is active. The company was incorporated on 5 October 2015 and lists its registered address as Minato Ward, Japan. 5 shareholders are on record for GSI Creos 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 2 October 2026.

Shareholders
5
Five shareholders are currently on record for GSI Creos 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 Small Cap Value Portfolio, holding 50.3% — a majority holding — followed by DFA Japanese Small Company Series at 16.9%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 10 shareholders in total, though only the top 5 by holding are shown in this view.
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.

The Chief Of Fiber Business Strategy Office, Md, Senior Managing Exec. Officer & Director of GSI Creos Co., Ltd. currently on record is Masateru Nakayama; five officers are currently on record for GSI Creos Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
The register reports 14 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at GSI Creos Co., Ltd. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
GSI Creos Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 15 subsidiaries recorded beneath it across 7 jurisdictions. 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 15 subsidiaries span Japan, Germany, China, Hong Kong, Taiwan, Vietnam, 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. Three of the 15 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
