edinet-document-searchlisted
Install: claude install-skill Kokai-Data/japan-business-intelligence
## When to use
Use this skill when:
- The user wants to see what disclosures a listed Japanese company filed recently.
- You need a date-bounded list of all 有価証券報告書 / 四半期報告書 / 大量保有報告書 / 公開買付届出書 etc. filed on a specific day or in a 90-day window.
- The user provides a 法人番号 (13-digit corporate number) and you want to confirm whether the company is listed (= has EDINET disclosures) before pulling further IR details.
- You're tracking 訂正報告書 / 取下書 events for signal monitoring.
- Pre-meeting research where past 開示履歴 matters (IR depth, governance signal).
## How to invoke
Call the kokai MCP server's `search_edinet_documents` tool:
```json
{
"name": "search_edinet_documents",
"arguments": {
"date": "<YYYY-MM-DD>",
"dateFrom": "<YYYY-MM-DD>",
"dateTo": "<YYYY-MM-DD>",
"docTypeCodes": ["120", "140", "350"],
"edinetCode": "<E12345>",
"corporateNumber": "<13-digit 法人番号>",
"limit": 50
}
}
```
Pass `date` for a single day OR `dateFrom` + `dateTo` for a range (max 90 days). `docTypeCodes`, `edinetCode`, `corporateNumber` are optional filters (combine freely). `corporateNumber` is auto-resolved to `edinetCode` via 30-day lookback (max 90).
