Shareholders
5
Five shareholders are currently on record for Rigaku Holdings 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 T. ROWE PRICE Intl Fd.S, INC.-T. Rowe Price Intl Discovery Fd., holding 25.4% — the largest recorded stake — followed by VANGUARD STAR FUNDS-Vanguard Total International Stock Index Fund at 18.8%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 8 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 Rigaku Holdings Co., Ltd. currently on record is Jun Kawakami; five officers are currently on record for Rigaku Holdings Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
The register reports 9 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Rigaku Holdings 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
Rigaku Holdings Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 5 subsidiaries recorded beneath it across 5 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 5 subsidiaries span Japan, Netherlands, Taiwan, Germany, Poland 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 5 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
