KDDI Corporation
KDDI Corporation is a registered legal entity registered in Japan under 9011101031552, 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 Shinjuku Ward, Japan. 5 shareholders are on record for KDDI 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 KDDI Corporation
Five shareholders are currently on record for KDDI 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 JANUS INVESTMENT FUND-Janus Henderson Global Equity Income Fund, holding 7.4% — the largest recorded stake — followed by VANGUARD WORLD FUND-Vanguard International Growth Fund at 7%; 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.
Data availability

The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.

Those 57 subsidiaries span Japan, Singapore, China, United Kingdom, Taiwan, Netherlands, and 5 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. 15 of the 57 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
