Group Structure

ROHM Co., Ltd. has no recorded parent company — it sits at the top of its own group structure, with 12 subsidiaries recorded beneath it across 5 jurisdictions. 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 12 subsidiaries span Japan, United States, Singapore, Philippines, United Kingdom 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. Six of the 12 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
