Litigation in Japan is initiated as soon as the plaintiff has filed a complaint in writing with a court, indicating a remedy sought & factually substantiating their claim. Once the court has looked into the claim, the defendant is sent a copy of the claim & subpoena. Should the defendant fail to respond, the court will consider it as a sign of consent with the factual information contained in the claimant’s written complaint.

Those contemplating filing a suit in Japan should keep in mind that the local courts can conduct oral proceedings or preliminary meetings to establish legal & factual matters & the required evidence. Conducting oral proceedings or holding preliminary meetings isn’t sequential & usually takes place once in 30 days

Settling a civil dispute in the state of Japan involves no juries, which means that veracity of supplied evidence gets checked by professional judges. It’s up to courts to decide whether evidence supplied by parties should be checked for veracity (and the same applies to questioning witnesses).

Procedures & Deadlines

Under Japanese legislation, interim relief can be requested by parties. Interim relief may also be applicable when it comes to settling business disputes in Japan’s courts. 

Class Action Suits

Filing class action lawsuits in Japan requires keeping in mind that this is a 2-stage process. The 1st stage involves obtaining a decision on liabilities existing between a business operator & their clients. Obtaining a declaratory decision is followed by clients’ filing a claim for damages against a business operator that’s held liable as per the declaratory decision. Following this, a notification of the initiation of the 2nd stage gets forwarded to clients & a public announcement in official newspapers is made. Consumers can then take part in a class action suit.

Japan: Enforcing Foreign Courts’ Decisions

Settling disputes in the state of Japan & enforcing judgments of foreign courts requires following a procedure prescribed in Japanese civil legislation. These are the requirements for recognizing judgements of foreign courts:

  • courts oversees must have legal power to try disputes as per international treaties & conventions;
  • a subpoena or order required for filing a suit have been served on a defendant;
  • foreign courts’ verdicts don’t contradict Japanese government’s policy;
  • foreign courts recognize decisions of Japanese courts and vice versa.

Once the above requirements are satisfied, foreign courts’ decisions will take effect & can be enforceable in the state of Japan.

Assisting Foreign Courts

Access to Court Records

It is possible for anyone to review documentation related to a case (including evidence), the only exception being documents to which confidentiality orders are applicable. Only participants to a dispute & 3rd parties legitimately interested in a case can be provided with access to case-related documentation. Access to case-related documents may be limited if there’s a risk that doing so may result in courts’ being unable to properly execute their duties.

Financing Litigation

Under Japanese legislation, individuals with low income are accorded legal services for free. That's not applicable to the settling of international commercial disputes in the state of Japan since assistance can’t be rendered to legal personalities.
