Shareholders
5
Five shareholders are currently on record for Aida Engineering 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 Price (T.Rowe) International Discovery Fund, holding 23.2% — the largest recorded stake — followed by iShares Core MSCI EAFE ETF at 5.1%; 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.

Officers
5
The Executive Officer & Director of Aida Engineering Co., Ltd. currently on record is Junichi Yonaiyama; five officers are currently on record for Aida Engineering Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
The register reports 10 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Aida Engineering 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
Aida Engineering Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 11 subsidiaries recorded beneath it across 8 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 11 subsidiaries span Japan, China, Germany, Italy, Malaysia, United States, and 2 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 11 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
