Fukushima Wastewater Release Stirs Seafood Market Uncertainty

fukushima wastewater release stirs seafood market uncertainty.jpg Business

Unease and uncertainty ripple through the seafood markets in Japan as the Fukushima Daiichi nuclear power plant begins the controversial release of treated radioactive wastewater into the Pacific Ocean. Despite the government’s assurances of safety and negligible environmental impact, the move has sparked widespread protests and diplomatic tensions, adding to the economic concerns already prevalent among the fishing community and related industries. The first auction since the water release began witnessed a mixed reaction, with prices of larger flounder, a signature Fukushima fish, falling by more than 10%, while some average-sized flounder saw a rise, likely due to limited catch.

The decision to release the treated wastewater, a process expected to last for decades, has been met with strong opposition from fishing groups and neighboring countries. China, in response, immediately imposed a ban on seafood imports from Japan, exacerbating the worries of the fisheries community. Thousands of South Koreans took to the streets, calling on Japan to store the radioactive water instead of releasing it into the ocean. Amid all this, the fishing groups in Japan fear that the release will further tarnish the reputation of Fukushima’s seafood, which they have been striving to rebuild since the 2011 earthquake and tsunami-triggered disaster at the power plant.

Mixed Reactions at Japanese Fish Auction After Release of Treated Water

The release of treated radioactive wastewater from the Fukushima Daiichi nuclear power plant on Thursday sparked mixed reactions at a fish auction in the nearby Numanouchi fishing port.

Price Fluctuations Amid Uncertainty

Hideaki Igari, a middleman at the fish auction, reported a drop of over 10% in the price of large flounder, known as Joban-mono and a signature catch of Fukushima. However, prices of some average-sized flounder rose, presumably due to limited catch, while others fell. This mixed response reflects the uncertainty over how consumers will react to the water release. Despite these fluctuations, Igari described the market reaction as relatively calm, but cautioned, “we still have to see how it goes next week.”

Opposition and Concerns for the Fishing Community

The decision to release the treated water was met with strong opposition from fishing groups, neighboring countries, and thousands of South Koreans who protested on the streets of Seoul. China also immediately banned imports of seafood from Japan, causing further worry among the fisheries community and related businesses. Japanese fishing groups, already dealing with the aftermath of the 2011 earthquake and tsunami, fear the water release could further damage the reputation of seafood from the Fukushima area and impact their livelihood.

Government and TEPCO’s Stance

The Japanese government and the plant’s operator, Tokyo Electric Power Company Holdings (TEPCO), argue that the release of water is necessary for the plant’s decommissioning and to prevent accidental leaks of insufficiently treated water. They assure that the treated and diluted wastewater is safer than international standards require, and its environmental impact will be negligible. However, the fishing community in Fukushima remains skeptical due to past incidents of contaminated water leaks.

Testing and Moving Forward

With the treated wastewater release predicted to take 30 years, the future of the fishing industry in Fukushima remains uncertain. Despite this, there are hopes that careful testing can prove the safety of their fish. As Ai Kimura, director of a citizens’ radiation testing center, expressed, "From the consumers’ point of view about food safety at home, I think the best barometer is data."


The release of treated wastewater from the Fukushima Daiichi nuclear power plant has sparked both economic and political concerns. The mixed reactions at the fish auction reflect the ongoing uncertainty in the fishing industry. While the government and TEPCO stand by the safety of the treated water, the skepticism among the fishing community and consumers indicates the need for comprehensive, transparent testing and data. The coming weeks will be crucial in determining the impact of this decision on the reputation of seafood from the Fukushima area and on the livelihood of the local fishing community.
