Shareholders
5
Five shareholders are currently on record for J-Oil Mills 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 28.9% — the largest recorded stake — followed by Vanguard International Stock Index-Total Intl Stock Indx at 18.1%; 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.

5
The President & Ceo of J-Oil Mills Co., Ltd. currently on record is Yuichiro Haruyama; five officers are currently on record for J-Oil Mills Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
The register reports 17 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at J-Oil Mills Co., Ltd. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
J-Oil Mills Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 4 subsidiaries recorded beneath it across 2 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 4 subsidiaries span Japan, India jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
