`gbiz_company_search`

Pack: gbizinfo · Endpoint: https://gateway.pipeworx.io/gbizinfo/mcp

Find Japanese companies and their 13-digit corporate numbers (法人番号) in gBizINFO, the Japanese government corporate registry run by METI. Search by company name, prefecture, corporate form, capital, employee count, revenue, or by whether the company has government procurement awards, subsidies, patents or filed financials. Returns each match with its corporate number, Japanese legal name, romanised name, registered address, capital and headcount. Requires an API key.

Parameters

Name	Type	Required	Description
`name`	string	no	Company name, partial match. PASS THE JAPANESE NAME WHERE YOU CAN (“トヨタ自動車”): a Latin-script query is matched against the romanised name field, which is sparse and dominated by municipal bodies — “Toyota” returns Toyota City property wards, not トヨタ自動車株式会社. The response flags this when it applies.
`prefecture`	string	no	Prefecture code, 2 digits from the JIS local-government code (13 = Tokyo, 23 = Aichi, 27 = Osaka).
`city`	string	no	Municipality code from the same JIS scheme.
`corporate_type`	string	no	Corporate form code: 301 株式会社 (joint-stock), 302 有限会社, 303 合名会社, 304 合資会社, 305 合同会社, 201 local government, 101 national body.
`has`	string	no	Restrict to companies that have records of a given kind: ${Object.keys(SOURCE_CODES).join(’, ’)}.
`capital_min`	number	no	Minimum capital stock in yen.
`capital_max`	number	no	Maximum capital stock in yen.
`employees_min`	number	no	Minimum employee count.
`employees_max`	number	no	Maximum employee count.
`founded_year`	string	no	Year of establishment, or several comma-separated.
`limit`	number	no	Companies to return, 1-100 (default 20).
`page`	number	no	Result page, 1-10 (default 1).
