The company was incorporated on 5 October 2015 and lists its registered address as Shinagawa Ward, Japan. 5 shareholders are on record for Cube System 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.

Shareholders
5
Five shareholders are currently on record for Cube System 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 Japanese Small Company Series, holding 59.5% — a majority holding — followed by DFA International Core Equity Portfolio at 16.1%; 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.

Officers
5
The Executive Managing Officer of Cube System Co., Ltd. currently on record is Kenkichi Kumagai; five officers are currently on record for Cube System Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.
The register reports 11 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Cube System 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
Cube System Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary recorded beneath it across 1 jurisdiction. 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 1 subsidiary spans Japan jurisdiction, 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.
