Japan Gov Owner Mapper

Map formal responsibility and adjacent policy involvement without mistaking a whitepaper mention for statutory ownership.

Do Not Use For

• Whether a topic is currently emphasized; use japan-gov-priority-checker.
• Which program receives funding; use japan-gov-budget-tracer.
• General thematic mentions without an ownership question.

Workflow

1. Define the theme, government level, decision context, and whether “owner” means statutory mandate, policy coordination, program delivery, or document framing.
2. Gather evidence in descending authority:
   1. laws, cabinet/ministerial orders, official organization and jurisdiction pages;
   2. Cabinet decisions, basic plans, headquarters/council documents, and named responsible-body assignments;
   3. current program, budget, implementation, or administrative-review records;
   4. whitepaper or report mentions.
3. Use ../../references/official-url-model.md and ../../references/egov-whitepaper-route-map.md for official document routes; cite the exact mandate or assignment location.
4. Label each body primary/formal, co-owner/coordinator, implementation owner, adjacent, or mention only.
5. Assign confidence:
   • high: current tier 1 evidence plus corroborating tier 2 or 3 evidence;
   • medium: explicit tier 2 assignment or consistent tier 3 responsibility without verified formal mandate;
   • low: whitepaper mention, indirect relevance, or stale/ambiguous responsibility only.
6. Check recency and central/local boundaries. Stop rather than force a single owner when responsibility is genuinely shared or not assigned.

Output

Role	Ministry/agency	Responsibility type	Evidence tier	Official basis	Current?	Confidence

Also include 主担当候補, 共同・周辺主体, 白書上の言及との違い, 所管が曖昧な点, and 誤分類リスク.

Guardrails

• Do not call a ministry the formal owner based only on a whitepaper or keyword hit.
• Do not present overlapping mandates as a conflict without evidence.
• Distinguish national jurisdiction, local implementation, independent agencies, and private roles.
