International Law

Japan has been making significant and constructive contributions towards the establishment of the rule of law in the international community.

First, Japan has been placing importance on peaceful settlement of international disputes. For example, it has accepted the compulsory jurisdiction of the International Court of Justice (ICJ), utilized the International Tribunal of the Law of the Sea (ITLOS) in the Hoshinmaru and Tomimaru Cases and has been a strong supporter of the International Criminal Court (ICC). Furthermore, Japan has sent Japanese judges to these distinguished judicial organs: President Hisashi Owada (ICJ), Judge Shunji Yanai (ITLOS) and Judge Kuniko Ozaki (ICC). Japan has also been one of the largest contributors to the Permanent Court of Arbitration (PCA).

Secondly, Japan has advocated the work relating to the progressive development and codification of international law, for example, by making constructive contributions to the discussion at diplomatic conferences on various international treaties, such as the Rome Conference on the ICC in 1998, or by submitting its views on the work of the International Law Commission (ILC) at the Sixth Committee of the United Nations. Professor Shinya Murase, Japanese member of the ILC, has been actively involved with the work of the ILC.

Thirdly, Japan has actively participated in the legal discourse at regional legal consultative organizations, such as the Asian-African Legal Consultative Organization (AALCO) (as a member) and the Committee of Legal Advisors on Public International Law of the Council of Europe (CAHDI) (as an observer).

Fourthly, Japan has made contributions to the establishment of the UN Audiovisual Library of International Law which was launched in October 2008.
