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
A JSON list of up to N matching Japanese legal entities, each including the corporate number (houjin bangou), official registered name, registered address, and potentially additional metadata about the entity.
Example use cases
Verify vendor registration for Japanese supplier
“I'm setting up a new partnership with a Japanese supplier. Can you search our corporate registry for '株式会社ソニー' and pull back their official legal name, corporate number, and registered address so I can confirm they're legitimate?”
Resolve customer company name to houjin number
“A customer just signed up and listed their company as 'NHK'. Can you look that up in the Japanese corporate registry to get their official houjin bangou and confirm their legal entity name and headquarters location?”
Build compliance checklist for Japanese partners
“We're doing due diligence on three potential Japanese business partners. Can you search the registry for 'ファーストリテイリング', 'ソフトバンクグループ', and 'パナソニック' to get their corporate numbers and registered addresses for our compliance records?”

Endpoint
GEThttps://api.kasanegi.com/v1/local/houjin-lookup/by-nameWhen to prefer
Use this endpoint when you need to resolve a Japanese company name to its official legal registration data, corporate number, or address — especially when building compliance workflows, due diligence pipelines, or vendor onboarding processes involving Japanese entities. Prefer this over scraping the NTA website directly.
