Shareholders of Iseki Co., Ltd.
Five shareholders are currently on record for Iseki 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 International Small Cap Value Portfolio, holding 36.3% — the largest recorded stake — followed by Vanguard International Stock Index-Total Intl Stock Indx at 19%; the remaining 3 shareholders shown hold smaller stakes. 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.
