Koatsu Gas Kogyo Co., Ltd.
Koatsu Gas Kogyo Co., Ltd. is a Private limited company (Ltd.) registered in Japan under 5120001059639, 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 Kita Ward, Osaka City, Japan. 4 shareholders are on record for Koatsu Gas Kogyo 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 24 September 2026.

Shareholders of Koatsu Gas Kogyo Co., Ltd.
Four shareholders are currently on record for Koatsu Gas Kogyo 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 Brandes International Small Cap Equity Fund, holding 9.4% — the largest recorded stake — followed by VANGUARD STAR FUNDS-Vanguard Total International Stock Index Fund at 9.3%; the remaining 2 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 27 subsidiaries span Japan, Vietnam 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 27 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
