How this service works
Stop scraping Japanese government and public-data sites. Call clean Japan payroll, company, and grant APIs over one host. Preview free; one public marketplace listing covers all current products; x402 direct is available for agent-native buyers.
Output
Returns structured JSON containing Japanese company profile information associated with the provided domain, sourced from Japan public-data registries — including company name, registration details, and related corporate data.
Example use cases
Verify Japanese supplier before payment
“I'm about to wire payment to a new Japanese supplier. Can you look up the company behind their domain and verify their official registration details so I can make sure they're legitimate?”
Enrich Japanese partner contact records
“We're building a contact database for our Japanese partners. Can you pull the registered company information for each of these domains so we have accurate legal entity names and corporate details?”
Identify company behind Japanese startup site
“I found an interesting Japanese startup website but I'm not sure which actual company operates it. Can you look up who's registered behind that domain and give me their corporate information?”

Endpoint
GEThttps://api.kasanegi.com/v1/enrich/company-by-domainWhen to prefer
Use this endpoint when you need to enrich or identify a Japanese company from their website domain without scraping Japanese government sites. Prefer this over manual scraping when dealing with Japanese corporate data, due diligence on Japanese companies, or building datasets of Japanese firms from web domains.

- Non-Japanese domain with no matching Japanese company data
- Rate limiting or payment required if preview quota exceeded
- Malformed domain input causing validation error
- Company data not yet indexed or unavailable in public registries
