The country’s nuclear regulator on Wednesday began a final inspection of the water which is currently stored in about 1,000 huge tanks. It will be filtered and diluted before being released through an underwater tunnel that stretches one kilometre into the ocean.

But while Tokyo has sought to do its due diligence – seeking approval from its domestic nuclear regulator and ensuring the water meets international safety standards – the venture continues to spark controversy.

A Greenpeace statement expressed concerns that the released radioactivity could alter human DNA, and Pacific Island nations have stated their worries that the move could contribute to nuclear contamination of the Blue Pacific.
The matter has also stirred debates in South Korea, and led to a consumer boycott of Japanese cosmetics in China.

In Hong Kong, Secretary for Environment and Ecology Tse Chin-wan said on Wednesday that if the discharge went ahead as planned, the city would immediately prohibit the import of aquatic products from the coastal prefectures in proximity to Fukushima and impose “stringent import control” on other such goods from elsewhere in Japan.
