get-egov-laws-data

When to use

Use this skill when:

• You have a law_id from search-egov-laws and need the actual statute text.
• The user asks "what does Article X of the Y Act say?" (e.g., "個人情報保護法 第15条").
• DD / legal research requires verbatim citation of statute text.
• You need to quote specific provisions in a due diligence brief or subsidy-fit analysis.
• Regulatory mapping requires the full chapter / article structure (法令の章立て).

How to invoke

Call the kokai MCP server's get_egov_laws_data tool:

{
  "name": "get_egov_laws_data",
  "arguments": {
    "law_id": "<law_id from search-egov-laws, e.g., 338AC0000000154>"
  }
}

law_id is required (obtained from search-egov-laws results).

Output structure

• law_id (input echoed)
• law_num (法令番号)
• title (法令名)
• enforcement_date / promulgation_date
• chapters (array of 章): each with chapter_num, chapter_title, articles (array of 条)
• Each article (条): article_num, article_title, paragraphs (array of 項), items (号)
• revision_info (改正履歴 summary if available)
• source_authority: "official" (公式 cite_required)
• attribution_text: "出典: e-Gov 法令検索 (デジタル庁) https://laws.e-gov.go.jp/law/<law_id>"
• source_url: direct e-Gov URL for the law's HTML view

Workflow pattern (paired with search-egov-laws)

1. User asks about a Japanese law topic
   ↓
2. search-egov-laws (keyword search) → list of candidate laws (10-20)
   ↓
3. User / agent selects one law_id
   ↓
4. get-egov-laws-data (law_id) → full statute text + structure
   ↓
5. Quote specific 条 / 項 / 号 with attribution_text + source_url

Differentiation from third-party sources

e-Gov 法令検索 is the only official statutory database for Japanese law. Third-party services (jurist sites, commentary platforms) provide interpretation but not 公式 text. When AI agent needs cite_required statute text:

• ✅ e-Gov (this skill) — 公式, current, デジタル庁 maintained
• ❌ Wikipedia / commentary sites — not cite_required for legal opinion

Boundary

• Output is verbatim statute text + structure — NOT legal advice or interpretation.
• 法令解釈 / 適用判定 / 法的助言 requires a certified Japanese 弁護士 / 行政書士 / 司法書士.
• Cite attribution_text + law_id + 条番号 + enforcement_date for any quoted provisions.
• Laws are amended frequently — always show the enforcement_date of the version retrieved.
• Never fictionalize statute text. If a law has been repealed (廃止), the API may not return it; in that case, note this and recommend lawyer consultation for historical research.
