Seex Co., Ltd.
Seex Co., Ltd. is a registered legal entity registered in Japan under 7120001080989, 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, Osaka City, Japan. 5 shareholders are on record for Seex 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 1 October 2026.

Shareholders of Seex Co., Ltd.
Five shareholders are currently on record for Seex 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 American Century ETF Trust-Avantis International Small Cap Value ETF, holding 20.4% — the largest recorded stake — followed by Vanguard International Stock Index-Total Intl Stock Indx at 8.6%; 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.

Those 17 subsidiaries span Japan, Hong Kong, China, Taiwan, Brazil, Philippines, and 7 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. Three of the 17 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
