Article 3-6Jurisdiction over a Joint Claim

If multiple claims are involved in a single action and the Japanese courts have jurisdiction over one of those claims and no jurisdiction over the others, the action may be filed with the Japanese courts only if the one claim is closely connected with the other claims; provided, however, that with regard to an action brought by multiple persons or an action brought against multiple persons, this applies only in the case specified in the first sentence of Article 38.
