Frontier issues in international ocean governance: Japan's discharge of nuclear contaminated water into the sea

Abstract

This paper aimed at explore international ocean governance issues through the perspective of Japan's nuclear contaminated water discharge to the sea. This paper analyzes the core issue of Japan's plan to discharge nuclear contaminated water into the ocean from the perspectives of Japan's international legal obligation, law enforcement issues, and judicial issues after integrated analyzing academic research paper and cases. Japan has obligations such as timely notification, information disclosure, environmental impact assessment, and avoidance of transboundary harm. Intergovernmental and non-governmental international organizations, such as IAEA, IMO and WHO should play a role in setting up an international group of experts to carry out monitoring and assessment, and whose positions and attitudes are important references for judging Japan's behavior. Cases heard before ICJ, ITLOS, and advisory opinion proceeding could provide reference from the judicial perspective on the issue of transboundary harm and proof of damages. Furthermore, this paper discusses the response strategies that the international community especially the opponents may adopt, including promoting the adoption of relevant treaties, take a combination of requesting advisory opinion and file arbitration, establish effective international monitoring mechanism, and engage in close communication with stakeholders.
