Woojin, Inc.
Woojin, Inc. is a Private limited company (Ltd.) registered in South Korea under 1358105713, and its current status with Supreme Court Internet Registry (IROS) is active. Its registered address on file is Hwaseong-si, South Korea. 5 shareholders are on record for Woojin, Inc., 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 Supreme Court Internet Registry (IROS) and was last updated on 30 September 2026.

Shareholders
5
Five shareholders are currently on record for Woojin, Inc., filed with Supreme Court Internet Registry (IROS).
The largest of these is DFA Emerging Markets Core Equity Portfolio, holding 49.7% — the largest recorded stake — followed by DFA Emerging Markets Small Cap Series at 23.6%; 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.

Officers
2
Two officers are currently on record for Woojin, Inc., filed with Supreme Court Internet Registry (IROS). Ryu Kye-hyeon and Sung-bum Lee both serve as Chief Executive Officer.
Management authority at Woojin, Inc. 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
Woojin, Inc. has no recorded parent company — it sits at the top of its own group structure, with 4 subsidiaries recorded beneath it across 2 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 4 subsidiaries span South Korea, Japan 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 4 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
