Output

Example use cases
B2B sales prospect verification
“We're targeting this Japanese manufacturing company for a partnership — can you grab their corporate registration details, business status, and any recent official announcements using their houjin number 9876543210123? I want to make sure they're legit before our sales team reaches out.”
Supplier compliance and vetting
“I need to onboard a new logistics supplier in Tokyo — can you look up their houjin number 5555555555555 and pull back their registration info, company details, and any financial disclosures from EDINET? I want to confirm they're in good standing.”
Due diligence for acquisition target
“We're evaluating a Japanese SaaS company for acquisition — can you enrich their profile using houjin 1111111111111? Pull everything you can from their corporate registration, any official gazette filings, and their latest financial disclosures so our legal team can review.”
Technical details
Endpoint
GEThttps://jp-data-enrich.kasanegi123.workers.dev/api/enrich/company-by-houjin-numberWhen to prefer
Use this endpoint when you need to enrich or verify a Japanese corporate entity and already have its 13-digit houjin (corporate registration) number. It is the right choice for KYB workflows, supplier vetting, B2B prospecting targeting Japanese companies, or any task requiring aggregated Japanese government data from gBizINFO, Kanpou, and EDINET in a single call. Prefer this over manual database lookups or general web search when structured, machine-readable Japanese corporate data is needed without requiring an API key.
Side effects
- Invalid or non-existent houjin number returns a 404 or empty result
- Malformed houjin number (not 13 digits) causes a 400 validation error
- Company not found in any of the three source databases returns partial or null data
- Payment failure via x402/USDC micropayment results in 402 Payment Required
- Upstream government API downtime causes 503 or timeout errors
