International Law

December 2, 2019

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 distinguished judicial organs such as Judge Yuji Iwasawa to the ICJ, Judge Shunji Yanai to the ITLOS and JudgeTomoko Akane to the ICC. Japan has also been one of the largest contributors to the Permanent Court of Arbitration (PCA).

In addition, 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 General Assembly. Professor Shinya Murase, Japanese member of the ILC, has been actively involved with the work of the ILC.

Moreover, 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).

These are some of the efforts by Japan in the realm of international law.
