Japan Fukushima controversial water release

Japan has started releasing treated radioactive water from the Fukushima nuclear plant into the Pacific Ocean on Thursday 25th August 2023. 

This is a controversial decision that has been opposed by China, South Korea, and some Pacific island nations. They fear that the water release will harm the marine environment and human health, and affect seafood exports.


Japan says that the water release is safe and necessary for the decommissioning of the plant, which was damaged by a massive earthquake and tsunami in 2011. The water has been treated to remove most of the radioactive substances, except for tritium and carbon-14, which are considered to have low risks. The water will also be diluted to meet the international standards for drinking water before being discharged.


The International Atomic Energy Agency (IAEA) has endorsed Japan’s plan and said that the water release will have a negligible impact on people and the environment. The IAEA will also monitor the water release and verify Japan’s compliance with the safety standards.

30 years

The water release is expected to take about 30 years to complete, and will involve pumping out about 1.34 million tonnes of water from more than 1,000 tanks at the Fukushima site.
