Market overview — Japan
Japan is a leading supplier of automotive components, industrial machinery, precision instruments, electronics, chemicals, and specialty food. The National Tax Agency issues the 13-digit Corporate Number (with a free public API); the Legal Affairs Bureau maintains the corporate registry (登記事項証明書); FSA's EDINET hosts listed-company disclosures. The principal verification topic is mis-identification of intermediaries vs. principals; 反社 (anti-social-forces) exposure is a low-frequency, high-severity overlay.
Why Japan verification matters
Japan is a leading supplier of automotive components, industrial machinery, precision instruments, electronics, chemicals, and specialty food. The National Tax Agency issues the 13-digit Corporate Number (法人番号); the Legal Affairs Bureau (法務局) maintains the corporate registry (登記事項証明書). Japanese corporate data is highly authoritative and most fraud risk concentrates not in the supplier's existence but in mis-identification of intermediaries vs. principals — sōgō shōsha (trading houses), distributors, and OEMs are often confused. Yakuza-related and 反社 (anti-social) exposure is a low-frequency but high-severity verification topic.
Common supplier fraud patterns in Japan
Distributor or trading house presents itself as a direct manufacturer of a Japanese brand; in fact the buyer is paying mark-up to an intermediary with no warranty pathway.
Counter-party has historical or current ties to designated organised-crime groups (指定暴力団) or anti-social entities (反社会的勢力).
An old 株式会社 with prestigious history is acquired and re-used to give a new venture credibility it has not earned.
Goods relabelled / re-finished in Japan to claim 'Made in Japan' origin when the substantial manufacture happened abroad.
Corporate supplier asks for payment to a personal Mizuho / SMBC / MUFG account or via personal PayPay / LINE Pay.
Electronics, gas, or consumer-protection suppliers present expired PSE / PSC / JIS certifications as current.

Payment risk notes for Japan
- 1Corporate account at a major Japanese bank in the Japanese legal name (with bank stamp on the confirmation letter) is the baseline standard.
- 2Personal PayPay / LINE Pay or personal-account routing for corporate payment is a near-certain fraud signal.
- 3Offshore HK / Cayman routing from a Japanese SME is rarely legitimate; listed multinationals may have documented related entities.
- 4JIS / PSE / PSC / CE certifications should be cross-checked against the issuing authority — not relied on from the supplier's PDF.

Japan supplier verification FAQ
How do I verify a Japanese supplier before payment?
Search the 13-digit Corporate Number on the NTA site to confirm legal name and registered address. Pull the 登記事項証明書 from the Legal Affairs Bureau for directors, capital, and corporate purpose. Verify the bank beneficiary in the Japanese legal name with the bank stamp. For orders above USD 10k, KeyBS Trust verification combines NTA, Legal Affairs Bureau, METI / NITE (if applicable), 反社 screening, and bank-beneficiary match.
What is the Corporate Number (法人番号)?
A 13-digit number issued by the National Tax Agency to every registered Japanese entity. The first digit is a check digit, followed by the 12-digit Companies Registry corporate number. It is the canonical identifier for any Japanese counter-party.
How long does Japan supplier verification take with KeyBS Trust?
Standard: 1–3 business days. Enhanced (with METI / EDINET / 反社 cross-check): 3–5 business days. Premium with Tokyo / Osaka / Nagoya on-site visit: 5–8 business days.
What is 反社 (han-sha) screening?
Anti-social-forces screening — verifying the counter-party has no current or historical ties to designated organised-crime groups or other anti-social entities. Japanese banks require it; corporate counter-parties increasingly do too. KeyBS conducts 反社 screening using Japanese-language sources from Enhanced upward.
What is the difference between a 株式会社 (KK), 合同会社 (GK) and a sōgō shōsha?
株式会社 is a joint-stock company. 合同会社 is a limited-liability company (LLC). A sōgō shōsha (e.g., Mitsubishi Corp., Mitsui & Co., Itochu, Sumitomo, Marubeni) is a general trading house — a 株式会社 that acts as an intermediary across many industries. Buying from a sōgō shōsha is legitimate; buying from one believing it is the manufacturer creates warranty and pricing-transparency risk.
Should I accept payment instructions to a Hong Kong or Cayman account from a Japanese supplier?
Rarely legitimate for a Japanese SME supplier. Listed multinationals may have documented related entities; SMEs almost never do. Unsolicited offshore routing is a strong fraud signal.
Can KeyBS check beneficial owners in Japan?
Yes — for non-listed entities via the Legal Affairs Bureau shareholder data and AML disclosure obligations, and for listed entities via EDINET. Sensitive findings (反社 exposure) are surfaced under controlled analyst review.
Does KeyBS verify JIS / PSE / PSC marks?
Yes — for electronics, gas appliances, and consumer-safety categories, the mark issuer (METI / NITE / accredited bodies) is verified against the live registry, not from the supplier's PDF certificate.
