How this service works
Dataset metadata for this Japanese (JP) corporate-number API — how many corporations are loaded and which prefectures are covered.
Output
Returns a JSON object with: loaded (boolean), data_source name (National Tax Agency of Japan), an array of all covered prefecture names in Japanese, prefecture_count (integer, up to 47), corporation_count (integer, e.g. 5,780,145), and attribution text.
Example use cases
Example prompt
“How many Japanese corporations are currently loaded in the houjin registry, and which of Japan's 47 prefectures are covered?”
Technical details
Endpoint
GEThttps://houjin.agentic-jp.com/statsWhen to prefer
Use this endpoint to verify dataset coverage and health before making corporate lookup queries — especially to confirm all 47 Japanese prefectures are indexed and to get the total corporation count. Prefer this over the lookup endpoint when you only need metadata about the dataset rather than information about a specific company.
Side effects
- Service unavailable: dataset not yet loaded (loaded: false)
- Network timeout if the stats endpoint is temporarily down
- Unexpected empty prefecture list if data indexing is in progress
