Addressing Japan’s disposal of nuclear-contaminated water from the perspective of international human rights law

The discharge of nuclear-contaminated water containing radionuclides into the ocean by Japan will lead to its integration into the entire ecosystem through processes of circulation and biomagnification, eventually entering the human body via the food chain. This poses a substantial risk of irreversible damage to both the ecosystem and human health, a situation that will worsen with the ongoing discharge of such water. The respect and protection of human rights represent an international consensus, and safeguarding fundamental human rights is a substantial obligation that states must undertake in accordance with both international and domestic law. Since the Fukushima nuclear disaster, Japan has continuously violated its international legal obligations to protect human rights in several areas, including the resettlement of disaster victims, the reduction of nuclear radiation levels, and the handling of contaminated water. Such actions have compromised and will continue to compromise the basic human rights of not only its citizens but also those of people worldwide, including environmental rights, the right to life, development rights, and food rights. In the aftermath of the Fukushima meltdown, the public and workers involved in handling nuclear contaminants have been continually exposed to high radiation levels, endangering their rights to life, development, and health. Japan’s inadequate efforts in victim resettlement and environmental restoration have jeopardized the environmental and food rights of its citizens to live healthily and access food in an environment unaffected by nuclear radiation. The release of nuclear-contaminated water poses a risk of Japan’s nuclear pollution to the people of neighboring countries and the global population at large. The principle of human rights underpins the theory of a community with a shared future for humanity, and human rights are a crucial area of China’s active participation in United Nations affairs and global governance. By voicing concerns over Japan’s potential human rights violations globally, China demonstrates its role as a responsible major country. In response to Japan’s breach of legal obligations and human rights violations, China can adopt a reasoned and beneficial approach, including calling on the international community to hold Japan criminally accountable for crimes against humanity under the Rome Statute and advancing scholarly discussions on ecocide and crimes against the marine environment. Furthermore, China should persist in seeking advisory opinions from the International Court of Justice and strive for substantive accountability, utilizing the mechanisms of international human rights organizations to make its voice heard.
