隨著交通工具的進步以及網路的發達，各國國際化的腳步逐漸加快，國際民事紛爭亦隨之增加，有關國際裁判管轄權之論述逐漸受到重視。我國就此部分的研討起步較晚，但與我國國情相似、地理位置相鄰的日本對此問題論爭已久，且近年來日本法務省更積極地進行民事訴訟法中有關國際裁判管轄權的立法工作。此外，有關日本國際裁判管轄之判斷方針與規定，亦會影響我國判決將來在日本被承認與執行的可能，故針對其國際裁判管轄權之現況與立法的相關議論，實有加以研究之必要。本文首先針對日本目前有關國際裁判管轄之學說見解及實務判決加以說明，其次，則就其擬於民事訴訟法中增修之相關條文重點逐項探討，以供我國將來在論述國際裁判管轄或立法時參考。

The purpose of this article is to present Japan's legal system regarding International Adjudicatory Jurisdiction, including recent legislative drafting, and to present some concrete issues which are currently being discussed in Japan. Japan's legislation relating to Adjudicatory Jurisdiction, known as the Code of Civil Procedure (CCP), did not contain certain provisions identified as the International Adjudicatory Jurisdiction, so the cases are very important in international civil and commercial jurisdiction. Recent Japanese cases illustrate an unique framework (so-called "Exceptional Circumstances Theory") to the treatment of jurisdictional issues. Desiring to promote international trade and investment, the Ministry of Justice of Japan starts to draft the rules on International Adjudicatory Jurisdiction designed to promote the certainty and ensure fairness between parties. The following sections will describe, first, the legal developments and issues currently being discussed in Japan, then the intent of the Drafters and some concrete issues mentioned during discussion.
