Fukushima, seven years on
by Hideyasu Tamura

More than seven years have passed since the Great East Japan Earthquake and subsequent accident at Tokyo Electric Power Co.’s Fukushima No. 1 nuclear power plant in 2011. A successful decommissioning of the plant and reconstruction of Fukushima is one of the most important missions of the government, especially the Ministry of Economy, Trade and Industry. Since 2016, I’ve been involved in the ministry’s special unit on Fukushima reconstruction, and mainly charged with a mission to eliminate reputational damage.
After the accident, the government set very stringent standards on the level of radioactive substances in food (in principle, 100 becquerel/kg: 10 times stricter than the Codex radionuclides standard), and any food product exceeding that level is prohibited for market distribution. Food products from Fukushima have undergone stringent monitoring, including all-volume inspection on rice and beef. Since 2015, not a single grain of rice or any piece of beef has been found with radioactive substances exceeding that level.
Nevertheless, around 12 percent of consumers in Japan tend to avoid agricultural and fishery products from Fukushima, according to a Consumer Affairs Agency survey. Since such reputational damage lingers even at home, the popular perception gap concerning Fukushima is likely even more serious overseas. With a view toward bridging that gap, I would like to highlight the following facts.
First, in the 12 municipalities in Fukushima Prefecture where evacuation orders were introduced after the nuclear disaster (Futaba, Hirono, Iitate, Kawamata, Kawauchi, Katsurao, Minamisoma, Namie, Naraha, Okuma, Tamura and Tomioka), the number of companies in the industrial estates has doubled from 35 before the disaster (in December 2010) to 70 in January. Some of the companies that have newly launched operation there engage in business that are relatively new to this area, such as the recycling of lithium-ion batteries and the production of internet-of-things devices that are wearable.
The establishment of the new companies have been facilitated by government incentives, including subsidies on investments that cover up to three-quarters of the investment cost, as well as the development of industrial infrastructure, such as the Fukushima Robot Test Field in Minamisoma and Namie. The test field, where any entity can use an extensive site (approximately 50 hectares) for demonstration experiments of robots and drones, is the core facility of the Fukushima Innovation Coast Framework.
This shows that the areas of Fukushima hit by the nuclear disaster have already become safe enough for businesses to operate. Private-sector companies never launch operations in locations where their employees’ safety is not ensured, even when the government provides most favorable incentives.
Second, as another proof of the area’s safety, the current situation of the Fukushima No. 1 plant should be highlighted. Today, workers can enter 96 percent of the site without any special radiation protection gear because the air dose rate has significantly decreased compared with right after the accident.
In addition, through multi-layered measures (e.g., the construction of frozen soil walls to suppress the inflow of groundwater as well as the pumping up of groundwater), the generation of contaminated water has been significantly reduced and prevented from leaking into the ocean. As a result, the concentration of radioactive materials in the sea water surrounding the plant has declined from 10,000 becquerels per liter as of March 2011 to below the detection limit (less than 0.7 becquerel per liter) since 2016.
The successful management of contaminated water has resulted in the improved safety of Fukushima’s fishery products. No marine products caught off Fukushima has exceeded the standard limit (100 becquerel/kg) in monitoring surveys over the fiscal years from 2015 to 2017.
Third, evacuation orders were lifted in many parts of the 12 municipalities by April 2017, and areas still under such orders account for approximately 2.7 percent of the prefecture’s total space — compared with 8 percent when the zoning was set in 2013. In several municipalities where evacuation orders were lifted up relatively early (such as the city of Tamura and the village of Kawauchi), around 80 percent of local residents have returned to their homes. Even in the areas where evacuation orders remain in place, efforts to improve the living environment have begun to pave the way for return of residents at the earliest possible time.
Needless to say, many challenges remain toward the successful reconstruction of Fukushima. The decommissioning of the Fukushima No. 1 plant is expected to take 30 to 40 years. To carry out the decommissioning, the retrieval of the melted nuclear fuel debris will be a major hurdle, and efforts to probe the inside of the reactor structures just started in 2015. In several towns where the evacuation orders were lifted only last year, less than 10 percent of local residents have returned to their homes. The improvement of living environment is an urgent task for those towns in order to encourage more residents to return.
Despite these challenges, the safety of Fukushima both in terms of its food products and the living/working environment in most parts of the prefecture has been proven. It is a pity that several countries/regions still impose import restrictions on Japanese food products (including those from Fukushima) and some people still hesitate to visit Fukushima for tourism or business. I wish that more people will visit Fukushima to taste the delicious and world’s safest rice, peaches and fish, and that more companies would be interested in utilizing advanced facilities/infrastructure such as the Fukushima Robot Test Field, and invest in Fukushima by taking advantage of the most favorable incentives in this country. Peaches will be harvested every year, but subsidies and other incentives will not last forever — so, the fast-movers will get the advantages.
