Toa DKK Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 9011101013864, 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 Shinjuku Ward, Japan. 2 shareholders are on record for Toa DKK 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

2

Two shareholders are currently on record for Toa DKK 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 Investment Dimensions-World Ex U.S. Core Equity Port, holding 2.6% — the largest recorded stake — followed by DFA Investment Dimensions-DFA International Social Core Equity Port at 1.9%.

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

5

The President, Ceo & Director of Toa DKK Co., Ltd. currently on record is Toshio Takahashi; five officers are currently on record for Toa DKK Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.

The register reports 11 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Management authority at Toa DKK 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

Toa DKK Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 5 subsidiaries recorded beneath it across 1 jurisdiction. 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 5 subsidiaries span Japan jurisdiction, 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.
