Japan's Fukushima nuclear accident was a big deal, and the 2011 earthquake tsunami triggered a nuclear leak, and then the treatment of nuclear waste water became an international hot spot. The official was named Dada Kangbo, when he was the Japanese Cabinet official, responsible for nuclear energy policy. On October 31, 2011, he drank a glass of treated water from Fukushima's First Nuclear Power Station at a news conference, which suddenly spread across the world. Many people wondered how many years have passed, and what is the person now? From various reliable sources, he was still alive, and there was nothing publicly about his death. In 2023, there were rumors online that he died, and he himself came out to clarify, saying those were fake. Now in 2025, he has retired from the political world, has been down the day

Dada Kangbo, born in 1967 in Qingdao County, studied law at the university and worked for a few years in the business after graduation. In the 1990s he moved from politics to join the Democratic Party and joined the grassroots party. In 2003 he was first elected to the House of Representatives, representing the Qingdao County electoral district. During the Democratic Party rule period, he rose quite quickly, in 2010 as the cabinet official, just hit the Fukushima accident. At that time he was mainly in charge of nuclear energy security and disaster reconstruction, and often dealt with Tokyo Electric Company. After the Democratic Party's departure in 2012, he lost his seat, and in 2014 he was re-elected, but not long ago, in 2015 he announced that he would not work, and went to the private sector.

The drinking water incident had to start from the beginning. After the Fukushima Nuclear Power Station incident, a large amount of radioactive waste water was accumulated, the Japanese government wanted to discharge, but domestic and international opposition waves. They said that after multi-layer purification, the radioactive concentration dropped below the standard, can be emitted safely. In order to convince everyone, Dada Kumbo drank the cup of water at the conference. The water was processed from the 5th and 6th units, placed in the glass. He said it was okay after drinking, but many people did not buy the bill. The International Atomic Energy Agency and some experts questioned at the time that purification, despite the majority of uranium and uranium, but this element was difficult to remove, half-life of more than 12 years

After the incident, the issue of nuclear wastewater in Japan has not stopped. Tokyo Power Company began to store wastewater since 2011, more and more tanks, and saved millions of tons by 2023. The government decided to discharge, starting from August 24, 2023, the first batch of emissions, and plans for a 30-year batch of 78,000 tons. The international community reacted vigorously, China directly banned the import of Japanese water products, and South Korea also protested. The UN Human Rights Council and some environmental organizations criticized, saying it would pollute the Pacific, affect fisheries and ecology. Experts calculated that uranium would spread along the ocean, within a few years to the North American coast, accumulating in fish. In 2024, Japan's emissions continued, several rounds, tens of thousands of tons in total. Monitoring data

Yasuhiro Sonoda's incident became a symbol. Many people take him as an example, saying that the Japanese government shows more than substance. After 2011, he continued to work, but the defeat of the Democratic Party frustrated his political career. When I retired from politics in 2015, I said it was personal reasons. Some people guessed that it was related to health, but there was no evidence. He later worked as a consultant in enterprises, focusing on energy consulting. In September 2023, it was suddenly reported on the Internet that he had died of cancer, possibly because the news of nuclear wastewater became popular again. As a result, he was interviewed and said that he was fine, and those rumors were made up. This is quite ironic, which shows that everyone's fear of nuclear wastewater is deeply rooted. Now in 2025, Japan's emissions are still continuing. Tokyo Electric Power announced plans in January to release 54,600 tons in seven rounds this year, similar to last year. The International Atomic Energy Agency sent a team to monitor and said it met the standards, but China and Pacific island countries were still uneasy and demanded more transparent data.

After the accident, Japan spent a lot of money on reconstruction, but wastewater treatment became a problem. Experts say that the concentration of uranium in the water after dilution was low, but the total amount was large, the ocean was not a garbage barrel. Fishermen's losses were severe, Japan's domestic fisheries produced a lot, and exports were harder. After China's ban, Japan turned to Southeast Asia market, but sales were not the same. Some studies showed that the level of radioactivity of Pacific fish rose slightly but did not reach the danger line. The World Health Organization and the International Atomic Energy Agency jointly that short-term risks were small but long-term food chain monitoring needed.

How old is Dada Kangbo now? 58 years old. From public information, he is no longer in politics, lives in Tokyo or᪸·, occasionally attends old colleagues' parties. There is no report that he got sick and got hospitalized, so probably still do. Many people in Japan's politics have done so after retirement, low retirement. His drinking water was considered a joke, but there are also people who say he was backpot, and the government pushed him out to shut him out. Nuclear waste water emissions to now, more than two years have passed, no large-scale pollution events, but the controversy has not disappeared. The latest news in September 2025 is that Tokyo Power said emissions went smoothly and the monitoring point data was normal. China's Customs Department is still banned from Japan's aquacul

Nuclear power is clean and efficient, but the accident sequelae are serious. Japan relies on nuclear energy, which accounted for 30% of electricity before the accident, but now it has dropped below 10%. It has switched to gas, and carbon emissions have increased. This is a warning in the global nuclear power renaissance. Yasuhiro Sonoda's move was to calm public opinion at that time, but the result was counterproductive. Now people pay more attention to factual data than performances. The 2025 report of the international expert group pointed out that although the emissions are in compliance with regulations, the model predicts that the tritium concentration can still be measured 20 years later, affecting the safety of seafood. Fishing workers complain that fish prices have fallen and fishing volume has decreased. Some island countries, such as Fiji, say that ocean currents bring radiation to them, which affects tourism.

The status quo of Dongdao Kangbo, there is nothing new to explode. His final public appearance was after 2023 speech. Probably in writing or lectures, but not confirmed. Compared to other officials, he did not count negative typical, is a policeman of the enforcement. The issue of nuclear waste water is wider, involving geopolitics. China pushed international monitoring, Japan agreed but delayed. In 2024, the International Atomic Energy Agency visited the day, sample analysis, saying uranium levels were lower than drinking water standards. But critics said that the standards were man-made and did not represent zero risk. Marine biologists study showed that algae and fish absorbed uranium into the food chain.

Tokyo's electricity plans to end in 2051, but technological progress may have new ways, such as evaporation or solidification of wastewater. Now the isolation of uranium is difficult, the cost is high. International cooperation is key, and in the China-Japan dialogue, nuclear wastewater is the topic. Gardena Kumbo is likely to watch the news at home and feel the fame of the year. Now young people may not know him, but the events are in the history book. He is still alive, the nuclear issue is still ongoing, everyone needs to pay more attention to the data, don't believe the rumors.
