Course Overview

The number of private international activities has been increasing steadily due to the borderless effect on the economy, and along with this the problems dealing with international law between individuals (or between private citizens and nations) are becoming more diverse and complicated. Overseas traffic accidents, international car robberies, extraterritorial applications of the antimonopoly act and the communications act as well as the conflicts of national laws and regulations, intervention in the international trade of nationalization, expropriation measures and asset freezing measures, large scale bankruptcy of multinational companies in multiple countries, and legitimacy of American exemplary damages judgments in our country are such examples of problems that are too many to count. Moreover, not only these property related cases, but also cases related to one's status such as international jurisdiction over divorce, legitimacy of foreign judgments ordering the surrender of children in our country, contention over children in international custody cases, the approval in our country of foreign judgments that have confirmed the parent-child relationship in surrogacy, are examples of international disputes that are also great in number.

Teacher's Tips

Private international law (conflict of laws) is law that is used to coordinate multiple related law systems. In comparison with civil law and commercial law, it is harder to understand in what situations problems will occur in the first place. Therefore, we aim for students to grasp a clear image of private international law by bringing up as many international civil affair dispute cases as possible. On the other hand, because private international law not only accepts Japanese law, but also accepts the application of foreign law and the approval and execution of foreign judgments, it raises the fundamental question of "why do we do this in the first place?" Therefore, in order for students to develop an interest in not only actual disputes, but also in theoretical problems, we will try to delve into theoretical issues as much as possible.
