Zuiko Co., Ltd.
Zuiko Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 7120901009526, 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 Ibaraki City, Japan. 5 shareholders are on record for Zuiko 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.

Shareholders
5
Five shareholders are currently on record for Zuiko 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 Japanese Small Company Series, holding 49.3% — the largest recorded stake — followed by DFA International Core Equity Portfolio at 27.4%; 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
5
The President, Ceo & Chairman of Zuiko Co., Ltd. currently on record is Toyoshi Umebayashi; five officers are currently on record for Zuiko Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
The register reports 6 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Zuiko 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
Zuiko Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 6 subsidiaries recorded beneath it across 4 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 6 subsidiaries span Japan, Thailand, Germany, Italy 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.
