Sumitomo Chemical Co., Ltd.
Sumitomo Chemical Co., Ltd. is a registered legal entity registered in Japan under 2010001071327, 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 Chemical 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. This profile is sourced directly from National Tax Agency — Corporate Number Publication Site and was last updated on 22 September 2026.

Shareholders of Sumitomo Chemical Co., Ltd.
Five shareholders are currently on record for Sumitomo Chemical 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 13.8% — the largest recorded stake — followed by iShares MSCI Japan ETF at 3.5%; the remaining 3 shareholders shown hold smaller stakes. 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.
