Shareholders of JMS Co., Ltd.
Five shareholders are currently on record for JMS 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 Core Equity Portfolio, holding 17.1% — the largest recorded stake — followed by DFA International Vector Equity Port at 3.4%; 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.
