The head of the Fukushima fisheries federation has again expressed opposition to the plan to release radioactive water from the crippled Fukushima Daiichi nuclear plant into the sea, local media reported on Wednesday.

During a meeting on Tuesday with the plant's operator Tokyo Electric Power Company (TEPCO), Tetsu Nozaki said the government and TEPCO had told the prefectural fisheries federation eight years ago that they would not dispose of the wastewater without gaining the understanding of the parties involved, the public broadcaster NHK reported.

Nozaki said he takes it seriously that the government and TEPCO have repeatedly provided explanations about the discharge plan, but the fishers have not endorsed it, according to NHK.

TEPCO completed the construction of the system to release nuclear wastewater from the facility into the sea on Monday. The Nuclear Regulation Authority (NRA) is due to start inspecting the system from Wednesday, the report said.

If the NRA gives the green light, the system will be ready for the discharge operation, which TEPCO plans to begin around this summer, it said.

Despite ongoing opposition from both home and abroad, Japan has been rushing to carry out its plan to dump radioactive wastewater into the Pacific Ocean, causing growing anger and stoking fears among the global community.

Japan's plan to dump nuclear wastewater into the sea "is not merely a nuclear safety issue. It is rather a nuclear legacy issue, an ocean, fisheries, environment, biodiversity, climate change and health issue with the future of our children and future generations at stake," Secretary-General Henry Puna of the Pacific Islands Forum (PIF) said in a statement on Monday.

Leaders from multiple Pacific Island countries have urged Japan "to store or dump their nuclear waste in their home countries rather than storing or dumping them in the Pacific," the statement said, adding that people from the Pacific Island countries have gained nothing from Japan's plans, which put future generations at great risk.
