Shareholders
5
Five shareholders are currently on record for Primaham 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 Pear Tree Polaris Foreign Value Small Cap Fund, holding 36.7% — the largest recorded stake — followed by Vanguard International Stock Index-Total Intl Stock Indx at 15.1%; 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.

Group Structure
Primaham Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 24 subsidiaries recorded beneath it across 3 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 24 subsidiaries span Japan, Thailand, Singapore 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. One of the 24 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
