Iseki & Co., Ltd.
Iseki & Co., Ltd. is a registered legal entity registered in Japan, and its current status with National Tax Agency — Corporate Number Publication Site is active. Its registered address on file is Arakawa-ku, Japan. 5 shareholders are on record for Iseki & Co., Ltd., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from National Tax Agency — Corporate Number Publication Site and was last updated on 1 October 2026.

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.
