Shareholders
5
Five shareholders are currently on record for Mimasu Semiconductor Industry 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 Goldman Sachs International Small Cap Insights Fund, holding 23% — the largest recorded stake — followed by Vanguard International Stock Index-Total Intl Stock Indx at 14.5%; 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.
