Sumitomo Mitsui Construction Co., Ltd.
Sumitomo Mitsui Construction Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 2010001131477, 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 Chuo Ward, Japan. 5 shareholders are on record for Sumitomo Mitsui Construction 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 Sumitomo Mitsui Construction 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 International Stock Index-Total Intl Stock Indx, holding 20.9% — the largest recorded stake — followed by iShares Core MSCI EAFE ETF at 12.5%; 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.

Group Structure
Sumitomo Mitsui Construction Co., Ltd. sits 1 level below its ultimate parent, INFRONEER HOLDINGS INC., registered in Japan. 19 subsidiaries are recorded beneath it, across 7 jurisdictions. The full chain up to INFRONEER HOLDINGS INC. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Sumitomo Mitsui Construction 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 19 subsidiaries span Japan, Guam, Singapore, Indonesia, Malaysia, India, and 1 more 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. One of the 19 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
