Search by name or registration number
A registration number returns exactly one entity. A name may return several, especially for groups using the same brand across entities.

Read the register entry, not the marketing page
The register entry shows Corporate Number (13-digit), Company name (Japanese/English). That is what a bank, auditor or counterparty will check.

Keep a dated copy
Register entries change. Save the record with the date you retrieved it, or set up monitoring so you are told when the entry changes.
