Shareholders
5
Five shareholders are currently on record for Artiza Networks 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 Old Westbury Small & Mid Cap Strategies Fund, holding 64.4% — a majority holding — followed by DFA Japanese Small Company Series at 14.7%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 6 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.

Takashi Tokonami serves as Co-founder & Chairman Of The Board; Naoyuki Tokonami serves as President, Ceo & Representative Director; Hideki Nagai serves as Head Of The Social Business Promotion Headquarters, Executive Officer & Director.
Management authority at Artiza Networks 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
Artiza Networks Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary 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 1 subsidiary spans 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.
