International Commercial Arbitration Basics: Procedure, Major Institutions, and Japanese Law

Key Takeaways

  • Key advantages of international arbitration over litigation: confidentiality, expert arbitrators, and enforcement in 170+ countries under the New York Convention
  • Arbitration agreements must be in writing (Arbitration Act Article 13); using a model clause from ICC, JCAA, etc. is recommended
  • Japan enacted the Arbitration Act in 2003 (based on UNCITRAL Model Law); foreign arbitral awards are enforceable under the New York Convention

What Is International Commercial Arbitration?

International arbitration is a process for resolving disputes between parties to international transactions before a private arbitral tribunal rather than a court.

New York Convention

The 1958 Convention on the Recognition and Enforcement of Foreign Arbitral Awards has 170+ signatories. It allows enforcement of foreign arbitral awards in domestic courts.

Major Arbitral Institutions

InstitutionCharacteristics

SIAC (Singapore International Arbitration Centre)Asia's largest; has emergency arbitrator procedure

Choosing an Institution

  • Counterparty's country: Choose an institution that facilitates enforcement there
  • Dispute value: Lower-cost institutions (e.g., JCAA) for smaller matters
  • Language: SIAC/ICC for English; JCAA for Japanese

Drafting Arbitration Clauses

Required Elements

A valid arbitration agreement requires (Arbitration Act Article 13): 1. Writing: agreement in writing or electronic record 2. Specified scope: e.g., "any dispute arising out of or in connection with this contract" 3. Exclusivity: language excluding court proceedings

Model Clauses (Recommended)

Each institution publishes a recommended model clause. Always use the institution's official model and add:

ItemContent
Seat of arbitrationMost critical legally (determines applicable procedural law)
LanguageJapanese or English
Number of arbitrators1 (small cases) or 3 (large cases)
Governing lawSpecify separately for contract substance and procedure

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.
