Shareholders
5
Five shareholders are currently on record for Maruichi Steel Tube 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 18.9% — the largest recorded stake — followed by HARTFORD MUTUAL FUNDS INC/CT-The Hartford International Value Fund at 12.9%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 14 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.

Management authority at Maruichi Steel Tube 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
Maruichi Steel Tube Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 14 subsidiaries recorded beneath it across 5 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 14 subsidiaries span Japan, United States, India, Philippines, Vietnam 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. Four of the 14 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
