Japan's Arbitration Act (2003)

Japan's Arbitration Act (Act No. 138 of 2003) is based on the UNCITRAL Model Law on International Commercial Arbitration.

Key provisions:

ArticleContent
Art. 13Requirements for arbitration agreement (writing required)
Art. 14Effect of arbitration agreement on court proceedings (dismissal of lawsuit)
Art. 28Arbitral tribunal's powers and interim measures
Art. 44Grounds for setting aside an arbitral award
Art. 46Recognition and enforcement of foreign arbitral awards

Grounds for Setting Aside (Article 44)

Arbitral awards are generally final and non-appealable, but courts may set them aside for: - Invalid or lapsed arbitration agreement - Denial of due process (no opportunity to defend) - Arbitral tribunal exceeding its authority - Violation of public order

Emergency Arbitrator Procedure

Institutions such as SIAC and ICC offer an emergency arbitrator procedure allowing parties to seek urgent interim relief (asset freeze, etc.) before the arbitral tribunal is constituted — a decision typically issues within days.

Summary

International commercial arbitration is the preferred dispute resolution mechanism for cross-border transactions due to its broad enforceability under the New York Convention and confidentiality. Use an institution's official model clause and specify the seat, language, and governing law. Japan's Arbitration Act enables enforcement of foreign awards, and Tokyo is growing as an Asian arbitration hub.
