Group Structure

Group structure of Tosoh Corporation

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.

  • TAIYO VINYL CORPORATION (Japan)
  • Tosoh (china) Investment Co., Ltd. (China)
  • TOHOKU TOSOH CHEMICAL CO., LTD. (Japan)

Data availability

Those 42 subsidiaries span Japan, China, Singapore, Vietnam, Philippines, United States, and 3 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. Eight of the 42 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
