RS Technologies Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 2011001145054, and its current status with National Tax Agency — Corporate Number Publication Site is active. The company was incorporated on 14 January 2022 and lists its registered address as Minato Ward, Japan. 5 shareholders are on record for RS Technologies 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 RS Technologies 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 Goldman Sachs International Small Cap Insights Fund, holding 20.8% — the largest recorded stake — followed by Vanguard Tax Managed Fund-Vanguard Developed Markets Index Fund at 13.7%; 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.
