概要と評価
Japan is a Contracting Party to the 1980 Hague Child Abduction Convention, in force since 2014-04-01 (Ratification). Its Accountability Index score is driven overwhelmingly by return performance — whether abducted children are actually returned (80% of the score) — with legal framework, judicial engagement and treaty integration as system-quality context.
評価の内訳
Japan scores 66.5 / 100 on the Hague Return Accountability Index — global rank #3 of 103, Tier 2 · Good performance. Return effectiveness — whether abducted children are actually returned — is 80% of the score; the remaining 20% is system-quality context (legal framework, speed, judicial engagement, cooperation, treaty integration).
1980年のハーグ条約（国際的な子の誘拐に関する条約）に基づき、各国が国際的に誘拐された子供をいかに適切に返還しているかを評価する公開インデックスにおいて、その計算方法を正確に示す。
Return effectiveness: measured return rate 60% of 180 concluded (shrunk to 58% toward the 39% global prior) → 63.6.
Legal framework: Legal framework (HCCH Country Profile): completed HCCH Country Profile / implementing framework (base 62); concentrated jurisdiction — 2 designated courts (Tokyo, Osaka) (+25) → 87.

データの質と限界
- Per-country return outcomes are not published; the 39% figure is a global aggregate.
- No public Central-Authority budget line located.
信頼度： Medium (0.51) — confidence reflects the strength and breadth of evidence, separately from performance. A low confidence means "we cannot yet fully evaluate," not "this country performs badly."
