Resonac Holdings Co., Ltd.
Resonac Holdings Co., Ltd. is a registered legal entity registered in Japan under 9010401014548, 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 Minato Ward, Japan. 5 shareholders are on record for Resonac Holdings 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

Shareholders of Resonac Holdings Co., Ltd.
Five shareholders are currently on record for Resonac Holdings 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 SMALLCAP WORLD FUND INC, holding 15.7% — the largest recorded stake — followed by MFS SERIES TRUST X-MFS International Growth Fund at 12%; 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, United States, India, Switzerland, Cayman Islands, Indonesia, 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. 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.
