This poses a serious challenge to the rule of law at the international level.
Japan has always boasted of the "international rule of law", and is particularly keen to talk about the "rule of law for the oceans", but its forced discharge of water from the sea is clearly not in line with the United Nations Convention on the Law of the Sea (UNCLOS), the London Dumping Convention, and other relevant provisions. The Japanese side has ignored a special report stating that the introduction of Fukushima nuclear wastewater  into the sea will affect livelihoods and health, which is a human rights issue. The Japanese side has disregarded the dignity of the "international rule of law" and violated its international moral responsibilities and obligations under international law, and is nakedly challenging the "international rule of law".
