PHC Holdings Corporation
PHC Holdings Corporation is a registered legal entity registered in Japan under 6010001155349, 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 Chiyoda Ward, Japan. 5 shareholders are on record for PHC Holdings Corporation, 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 PHC Holdings Corporation
Five shareholders are currently on record for PHC Holdings Corporation, 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 iShares Trust-iShares MSCI EAFE Small-Cap ETF, holding 7.7% — the largest recorded stake — followed by VANGUARD Intl Eqy. INDEX Fd.S-Vanguard FTSE All-World ex-US Small-Cap at 6.5%; 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.

Those 11 subsidiaries span Japan, Switzerland, Netherlands, Mexico, Singapore, United States 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.
