First Brothers Co., Ltd.

Shareholders
5
Five shareholders are currently on record for First Brothers 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 53.3% — a majority holding — followed by DFA Japanese Small Company Series at 40.2%; 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.
