With the globalization of the economy and the development of science, technology, and information and communication, all events in today’s society bear some form of internationality. In the Department of International Legal Studies, students study law on international relations in order to acquire the ability to analyze various problems in the international community. On top of the strong foundation in domestic law, students will study international relations from the perspective of political science and will be trained to become diplomats, officials of international organizations, international lawyers, and international legal affairs staff in corporations, who will be active players in the international arena of the future. Of course, language skills and cultural education are also important in the international context, and we provide a well-balanced arrangement of courses to meet such demands.
In the first year, students learn the basic method of studying law and political science, take basic law courses such as The Japanese Constitution and General Provisions Civil Code, and then deepen their study in international-related courses such as International Law, International Private Law, International Business Law, and Common Law. In addition to basic legal studies, students will acquire the ability to systematically understand diverse world events and international relations from diverse perspectives with courses such as Political Science and International Politics. After special lectures by invited lecturers from the Ministry of Foreign Affairs and other ministries who have practical experience, students are exposed to real-life law and politics, and in the compulsory Seminar in the fourth year, they hone their abilities to tackle specific issues.
