The company was incorporated on 5 October 2015 and lists its registered address as Imari City, Japan. 5 shareholders are on record for IKK 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 IKK Holdings Co., Ltd.
Five shareholders are currently on record for IKK 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 DFA International Core Equity Portfolio, holding 55.8% — a majority holding — followed by DFA Japanese Small Company Series at 15.6%; 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.
