Sumishi Holdings Co., Ltd.
Sumishi Holdings Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 2010401078384, and its current status with National Tax Agency — Corporate Number Publication Site is active. The company was incorporated on 5 October 2015 and lists its registered address as Minato Ward, Japan. 5 shareholders are on record for Sumishi Holdings 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 Sumishi Holdings 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 VANGUARD STAR FUNDS-Vanguard Total International Stock Index Fund, holding 17.5% — the largest recorded stake — followed by DFA Japanese Small Company Series at 13.8%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 8 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.

The Executive Officer, Gm Of Financial & General Affairs Department And Director of Sumishi Holdings Co., Ltd. currently on record is Yoshinori Miyazawa; five officers are currently on record for Sumishi Holdings Co., Ltd., filed with National Tax Agency — Corporate Number Publication Site.

Management authority at Sumishi Holdings 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
Sumishi Holdings Co., Ltd. sits 1 level below its ultimate parent, ASO CORPORATION, registered in Japan. 4 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to ASO CORPORATION is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Sumishi Holdings Co., Ltd.'s own shareholder record. 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 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.
