Group Structure
Kioxia Co., Ltd. sits 1 level below its ultimate parent, KIOXIA HOLDINGS CORPORATION, registered in Japan. 16 subsidiaries are recorded beneath it, across 7 jurisdictions. The full chain up to KIOXIA HOLDINGS CORPORATION is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Kioxia Co., Ltd.'s own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 16 subsidiaries span Japan, Singapore, United States, Taiwan, Hong Kong, China, 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. Two of the 16 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
