aibot88 When to use
Use this skill when:
- The user provides a 13-digit Japanese 法人番号 (corporate number).
- You need authoritative status of the corporation: active / dissolved / merged / closed.
- You need change history: name changes, address moves, merger events.
- gBizINFO returned no record (small / new / non-METI-tracked entity) and you want NTA fallback.
- M&A due diligence, KYC verification, or pre-meeting research where past 沿革 matters.
How to invoke
Call the kokai MCP server's get_nta_corporate_record tool:
{
"name": "get_nta_corporate_record",
"arguments": {
"corporate_number": "<13-digit 法人番号>",
"include_history": true
}
}
Output structure
The response includes:
- latest: the current authoritative record (name, address, kind, process status, assignment date)
- history: previous records (name changes / address moves / etc., sorted by date desc)
- is_dissolved / is_merged: boolean flags for closure status
- process_summary: human-readable summary like "3 件の異動履歴あり (商号変更 / 国内所在地の変更 ...)"
- process_label: 公式 process classification (01=新規 / 11=商号変更 / 12=移転 / 71=合併解散 / 81=抹消 / 99=削除)
- source_authority: "official" (公式 cite_required layer)
- terms_of_use: cite gBizINFO terms

Pair this skill with gbizinfo-entity-lookup for full coverage.
Boundary
- Output is signal / 確認材料 / context — NOT a decision.
- Final 申請可否 / 法的判断 requires a certified Japanese 士業 (行政書士 / 中小企業診断士 / 公認会計士 / 弁護士).
- Cite source_url + retrieved_at + 国税庁 attribution in final output.
- Never fictionalize. If NTA returns "no record" for a valid 法人番号, the corporation may have been recently dissolved.
