Documents to collect

The physical documents you’ll collect from your customer, with the evidence area each one proves. One document can prove multiple areas — for example, Brazil’s Cartão CNPJ covers both tax and business-registration proof, so it appears once with both areas listed.

Collection notes

  • Legal Registration: Issued by Legal Affairs Bureau; order online via MOJ e-registration portal or in person.
  • Constitutive Documents: KK: notarised by MOJ kōshōnin (Companies Act Art. 30). GK: self-attested, notarisation not required.
  • Tax Registration: 13-digit Corporate Number; downloadable from houjin-bangou.nta.go.jp; also accept Nōzei Shōmeisho (納税証明書) as proof of tax payment.
  • Sector-Specific License: Sector-specific authorisation under statute — FSA registrations under the Banking Act, the Insurance Business Act, the Payment Services Act (funds-transfer / prepaid / crypto-asset exchange providers), and the FIEA Financial Instruments Business Operator regime; PPC registrations under the APPI for data-handling businesses. Collect only the licence(s) applicable to the customer’s regulated activity.
  • Governance Records: Directors and rep-director listed on the extract; as of 2024-10-01 residential addresses may be partially redacted to prefecture/ward level.
  • Signing Authority: Bundle: Inkan Shōmeisho certifies rep-director’s registered seal + Tōki-jikō Shōmeisho confirms appointment; add board resolution for non-routine transactions.
  • Address: Conduit universal policy: lease (no time bound) OR utility bill OR bank statement, with utility/bank dated within 90 days. Same evidence satisfies both registered-address and operating-address checks.

Person roles

When you submit a person on the application body, set their role to one of Conduit’s canonical BusinessPersonRole values. Use this table to map a local corporate-governance title onto the right canonical role.
Local roleCanonical API roleDescription
Daihyō Torishimari-yaku (代表取締役)LEGAL_REPRESENTATIVEKK rep-director; legally binds the company; registered in Tōki-jikō Shōmeisho.
Torishimari-yaku (取締役)CONTROLLING_PERSONKK board director; governance/oversight role.

Notes

  • Inkan Shōmeisho is the primary signing-authority instrument. Common-law-trained integrators default to a board resolution alone; in Japan, the Inkan Shōmeisho authenticates the rep-director’s registered seal. Always collect it alongside the Tōki-jikō Shōmeisho.
  • KK and GK Teikan notarisation differ. KK Teikan requires MOJ notary (kōshōnin) per Companies Act Art. 30; GK Teikan is self-attested. Requesting a notarised GK Teikan will cause processing delays.
  • Director address redaction (eff. 2024-10-01). MOJ amended Commercial Registration Regulations; KK representative directors may now apply to show only prefecture/ward on the registry extract, not full street address. Verify via direct CDD if precise address is required.
