Recognition and Enforcement of Foreign Judgments in Japan: Civil Procedure Act Article 118

Key Takeaways

  • Enforcement of a foreign judgment in Japan requires satisfaction of all four conditions under Civil Procedure Act Article 118: finality, jurisdiction, public policy, and reciprocity
  • The "reciprocity" requirement is a practical hurdle — only judgments from countries that would similarly enforce Japanese judgments are recognized
  • Enforcement requires a separate "enforcement judgment" action (Civil Execution Act Article 24); recognition and enforcement are distinct proceedings

Recognition vs. Enforcement of Foreign Judgments

Enforcing a foreign court judgment in Japan requires two steps: recognition (accepting its legal effect) and enforcement (obtaining an enforcement judgment to execute it).

ConceptContent
RecognitionAccepting the judgment's legal effects (res judicata, etc.) in Japan
EnforcementCompelling performance in Japan based on the judgment

Recognition may occur automatically in some contexts, but enforcement requires a separate enforcement judgment action (Civil Execution Act Article 24).

Four Requirements for Recognition (Civil Procedure Act Article 118)

Requirement 1: Finality

The foreign judgment must be final and binding (appeal period expired, appeal rejected, etc.).

Requirement 2: Jurisdiction

The foreign court must have had proper international jurisdiction, assessed by Japanese CPA and treaty standards: - Defendant had domicile/principal office in the judgment country - Contract to be performed in the judgment country - Parties agreed to that court's jurisdiction

Note: Jurisdiction based solely on the defendant's nationality may not be recognized.

Requirement 3: No Violation of Public Policy (Article 118(iii))

Recognition must not violate Japan's public order or good morals.

Examples of public policy violations: - Punitive damages exceeding actual harm - Judgments obtained through procedures violating basic principles of Japanese civil procedure - Judgments contrary to fundamental constitutional values

Requirement 4: Reciprocity (Article 118(iv))

The foreign country must recognize Japanese judgments under similar conditions.

StatusExamples
Reciprocity establishedUSA (most states), Germany, France, UK
ContestedChina (recent cases have accepted), South Korea
Not establishedMany developing countries

Enforcement Judgment Procedure (Civil Execution Act Article 24)

To enforce a foreign judgment in Japan, file an enforcement judgment action in a Japanese district court.

Steps

  1. Translate and authenticate the foreign judgment
  2. File the action in the district court at the debtor's domicile
  3. Court reviews the Article 118 requirements
  4. Enforcement judgment: if requirements are met, the court declares the judgment enforceable
  5. Enforcement: standard execution proceedings (asset seizure, etc.)

US Punitive Damages

US punitive damages often far exceed actual harm.

Japanese Supreme Court (July 11, 1997): The compensatory portion of a US punitive damages award is recognizable; the punitive/deterrent portion violates public policy and is not recognizable.

Foreign Judgments vs. Foreign Arbitral Awards

ItemForeign JudgmentForeign Arbitral Award
Legal basisCPA Art. 118; CEA Art. 24New York Convention; Arbitration Act Art. 46
Reciprocity requiredYesNo (between Convention states)
Enforceable inLimited to treaty states170+ countries

Practical implication: For international commercial disputes, international arbitration offers far more reliable cross-border enforcement than court judgments.

Summary

Enforcing a foreign judgment in Japan faces significant hurdles under CPA Article 118, particularly the reciprocity requirement. Judgments from countries without established reciprocity may not be recognizable. In international transactions, selecting international arbitration as the dispute resolution mechanism — enforceable in 170+ countries under the New York Convention — is strongly recommended.
