TOKYO (Kyodo) — Japan’s nuclear watchdog on Wednesday gave the green light to the restart of an aging nuclear power plant northeast of Tokyo, idled since it was hit by the tsunami that caused meltdowns at the Fukushima Daiichi plant.
The Tokai No. 2 plant is the first nuclear plant affected by the March 2011 earthquake and tsunami disaster to have cleared screening by the Nuclear Regulation Authority, part of the steps required before it can actually resume operations.
The plant, located in the village of Tokai in Ibaraki Prefecture, suffered an emergency automatic shutdown of its reactor and was cut off from its external power source following the quake.
After being hit by a 5.4-meter tsunami, one of its three emergency power generators was incapacitated. But the other two remained intact and allowed the reactor to cool down three and a half days after the disaster.
Despite the approval by the NRA, the Tokai plant still needs to clear two more screenings by regulators by November, when it will turn 40 years old, otherwise it could face the prospect of decommissioning.
Tougher safety rules introduced in the post-Fukushima years prohibit in principle the operation of nuclear reactors beyond 40 years. But extending a unit’s life for an additional 20 years is possible if operators make safety upgrades and pass regulators’ screening.
Actual plant operation is unlikely before March 2021 when construction to bolster safety measures is scheduled to be completed. The restart plan also needs to be approved by local municipalities.
The Tokai No. 2 plant, operated by Japan Atomic Power Co., uses a boiling water reactor, the same type as those used at the crisis-hit Fukushima Daiichi plant, which saw core meltdowns and spewed a massive amount of radioactive materials into the atmosphere in the 2011 disaster.
It is the eighth plant approved of a restart under the stricter safety rules introduced after the 2011 Fukushima nuclear crisis and the second with a boiling water reactor following the Kashiwazaki-Kariwa nuclear plant run by Tokyo Electric Power Company Holdings Inc.
The plant’s evacuation plan — which covers 960,000 residents, the largest number of potential evacuees for a nuclear plant in Japan due to its location in a metropolitan area — has yet to be compiled.
The operator filed for a safety screening to restart the plant in May 2014. It predicts a potential tsunami as high as 17.1 meter and expects some 180 billion yen ($1.63 billion) is needed to construct coastal levees and beef up power sources among other safety measures.
Japan Atomic Power solely engages in the nuclear energy business but none of its reactors has been online since the 2011 quake. Given its financial problems, the NRA has asked it to show how it will finance the safety measures and Tokyo Electric Power and Tohoku Electric Power Co. have offered to financially support the company.
Ibaraki citizens demonstrate against the restart of the Tokai No. 2 nuclear power plant outside the Nuclear Regulation Authority headquarters in Tokyo’s Minato Ward on Wednesday.
Nuclear watchdog OKs restart of aging tsunami-hit Tokai nuclear plant

Ibaraki unit needs to clear two more screenings by November, when it will turn 40
The Nuclear Regulation Authority on Wednesday gave the green light to the restart of an aging nuclear power plant northeast of Tokyo, idled since it was hit by the tsunami that caused meltdowns at the Fukushima No. 1 plant.
The Tokai No. 2 plant is the first nuclear plant affected by the March 2011 earthquake and tsunami disaster to have cleared screening by the nuclear watchdog. Other steps are still required before it can resume operations.
Due to the quake, the plant in the Ibaraki Prefecture village of Tokai suffered an emergency automatic shutdown of its reactor and was cut off from its external power source.
After then being hit by a 5.4-meter tsunami, one of its three emergency power generators was incapacitated. But the other two remained intact and allowed the reactor to cool down 3½ days after the disaster.
Despite the approval by the NRA, the plant still needs to clear two more screenings by regulators by November, when it will turn 40 years old. If it fails, it could face the prospect of decommissioning.
Following the decision, Ibaraki Gov. Kazuhiko Oigawa told reporters he intends to “closely monitor the remaining screenings” and called on the NRA “to conduct strict examinations.”
Tougher safety rules introduced after the Fukushima disaster in principle prohibit the operation of nuclear reactors beyond 40 years. But extending a unit’s life for an additional 20 years is possible if operators make safety upgrades and it passes screenings.
Actual operation is unlikely before March 2021, when construction to bolster safety measures is scheduled to be completed. The restart plan also needs to be approved by local municipalities.
On Wednesday morning, a group of about 10 citizens protested the restart outside the NRA’s offices in Tokyo’s Minato Ward.
Mika Tsubata, a 47-year-old resident of Tokai who observed the NRA meeting, blasted the decision. “The Tokai No. 2 plant is old and was damaged in the 2011 disaster,” she said. “It’s evident to everyone that (the restart) is highly risky — I don’t think the NRA made the appropriate decision.”
But Eiji Sato, the 69-year-old chair of the village’s chamber of commerce, said the plant’s resumption is key to Tokai’s future. “The village has thrived on nuclear power generation,” he said.
The Tokai No. 2 plant, operated by Japan Atomic Power Co., uses a boiling-water reactor, the same type as those used at the Fukushima No. 1 plant, which suffered core meltdowns and spewed a massive amount of radioactive material into the atmosphere in 2011.
It is the eighth plant to get approval for a restart under the stricter safety rules and the second with a boiling-water reactor, following the Kashiwazaki-Kariwa plant, run by Tokyo Electric Power Company Holdings Inc.
The plant’s evacuation plan — which covers 960,000 residents, the largest number of potential evacuees for a nuclear plant in Japan due to its location near a metropolitan area — has yet to be compiled.
“Because of the large number of residents around the plant, compiling effective anti-disaster measures and an evacuation plan in a wide area is a huge challenge,” Oigawa said.
The operator filed for a safety screening to restart the plant in May 2014. It predicts a potential tsunami as high as 17.1 meters and expects ¥180 billion ($1.63 billion) will be needed to construct coastal levees and beef up power sources, among other safety measures.
Although Japan Atomic Power’s sole business is nuclear energy, none of its reactors has been online since the 2011 quake. Given its financial problems, the NRA has asked the utility to show how it will finance the safety measures. Tepco and Tohoku Electric Power Co., which had been receiving electricity from the plant when it was in operation, have offered to financially support the company.
The NRA decided at the meeting to seek industry minister Hiroshige Seko’s views on whether Tepco’s financial contribution could affect the costs of scrapping the Fukushima No. 1 plant and enhancing safety at the Kashiwazaki-Kariwa plant.
Tourists in Fukushima Nuclear Disaster Zone to Stay Away!
English signs along National Road No. 114 on the border between Namie and Kawamata in Fukushima Prefecture
English signs tell tourists to stay away from Fukushima plant
July 4, 2018
NAMIE, Fukushima Prefecture–English signs now appear along roads in Fukushima Prefecture to prevent curious, thrill-seeking or simply ignorant foreign tourists from entering areas of high radiation.
The central government’s local nuclear emergency response headquarters set up 26 signs at 12 locations along the 70-kilometer National Road No. 114 and elsewhere starting in mid-April. The signs carry straightforward messages in English, such as “No Entry!”
In September, a 27-kilometer section of the road opened in Namie’s “difficult-to-return zone” near the crippled Fukushima No. 1 power plant for the first time since the Great East Japan Earthquake, tsunami and nuclear disaster in March 2011.
The road is mainly used by construction vehicles involved in rebuilding projects and dump trucks transporting contaminated soil to intermediate storage facilities.
Motorists can use the reopened section, but they are urged to refrain from stopping or venturing outside their vehicles. Pedestrians and motorcyclists are still forbidden from the area because of the high radiation levels.
But an increasing number of people from abroad are visiting the area, some to snap photos, according to Fukushima prefectural police.
Many have gotten out of their vehicles or entered the “no-go” zone by motorbike or foot.
Prefectural police asked the central government for help to deal with the trespassers.
“When police questioned foreigners who were taking photos in the difficult-to-return zone, they said they did not know that entering the area was prohibited,” a police official said.
Officials also wanted to avoid any confusion from the signs with technical terms, such as “difficult-to-return zones,” which are the areas most heavily polluted by radiation that remain essentially off-limits even to residents.
An official of the Cabinet Office’s nuclear disaster victim life assistance team, which developed English messages, said they decided to use simpler expressions, such as “high-dose radiation area,” for the signs.
The signs have already produced a positive effect.
“A foreign motorcyclist came here the other day, so I told the person to return by pointing to the English signboard,” said a security guard who monitors the Namie-Kawamata border zone at the Tsushima Gate.
Tourists told to stop taking selfies in Fukushima nuclear disaster zone

4 July 2018
Authorities in Fukushima are installing warning signs in English telling thrill-seeking tourists not to stop their cars or pose for selfies in areas that still have dangerously high levels of radiation.
Seven years after the disaster at the prefecture’s nuclear plant, the government’s nuclear emergency response office has placed 26 signs along a 45-mile stretch of National Road 114 and a number of smaller roads in areas designated as “difficult-to-return” for local residents, the Asahi newspaper reported.
One road through the town of Namie was only reopened in September and is primarily used by construction vehicles and lorries removing contaminated waste and debris to landfill sites.
Motorists are able to access the roads, but authorities have installed signs after tourists were spotted getting out of their cars to take photos. Pedestrians, cyclists and motorcyclists are still banned from entering the restricted zone.
The signs read “No Entry!” for motorcycles, mopeds, light vehicles, bicycles and pedestrians, while others warn of “High-dose radiation area” and advise “Please pass through as quickly as possible”.
Fukushima police said they were forced to appeal to the government for help because of the rising number of incidents involving tourists who were unaware that getting out of a vehicle transiting the zone is still prohibited.
The areas that still have levels of radiation that would be harmful to human health lie to the north-west of the Fukushima nuclear plant and were under the plume of radioactivity released when a series of tsunami destroyed the cooling systems of four reactors in March 2011.
Local residents are permitted to return to their homes for brief, closely supervised visits, but the government admits that despite efforts to decontaminate the region, it will be many years before they are able to return on a permanent basis.
Long considered one of Japan’s most unspoilt and beautiful prefectures, Fukushima is today trying to rebuild a reputation among foreign and domestic tourists. A number of other travel firms are now offering tours to some of the towns most severely damaged as a result of the magnitude-9.1 earthquake, the tsunami it triggered and the nuclear disaster.
Radiation still too high in reactor# 2 building
July 2, 2018
A robotic probe has found that radiation levels remain too high for humans to work inside one of the reactor buildings at the damaged Fukushima Daiichi nuclear power plant.
Tokyo Electric Power Company, the operator of the plant, plans to relocate 615 units of nuclear fuel from the spent fuel pool, which is located on the top floor of the No. 2 reactor building and is separate from the reactor itself.
TEPCO says the relocation will help reduce risks, including possible damage caused by earthquakes.
The No. 2 reactor underwent a meltdown, but did not experience a hydrogen explosion in the 2011 nuclear accident. The building is likely to still have a high concentration of radioactive materials.
Last month, TEPCO drilled a hole in the wall of the building in order to use a camera-equipped robot to create a detailed map of the radiation on the top floor.
On Monday, workers started the survey and measured radiation levels at 19 points, mainly near the opening. Up to 59 millisieverts were detected per hour.
That’s above workers’ allowable annual exposure of 50 millisieverts and more than half of their 5-year exposure limit. TEPCO has concluded it cannot let humans work inside the building.
TEPCO will use the results to determine specific ways to remove the fuel from the pool. It plans to start the work in fiscal 2023.
TEPCO aims to build more Fukushima-type nuclear reactors, vows to ‘excel in safety’ this time
Fukushima Daiichi nuclear power plant
1 Jul, 2018
TEPCO is conducting an independent geological survey to confirm the absence of active faults in Aomori Prefecture, where it wants to resume the construction of a Fukushima-type nuclear plant, frozen following the 2011 disaster.
“It’s necessary to form a consortium for building a nuclear plant that is excellent in safety, technology and economy,” TEPCO President Tomoaki Kobayakawa said in Tokyo, announcing the decision to conduct a survey of the Aomori Prefecture nuclear site.
The Higashidori Nuclear Power Plant hosts two adjoining sites administered by Tohoku Electric Power Company and Tokyo Electric Power Company (TEPCO). While Tohoku Unit 1 began commercial operations in December 2005, TEPCO never got a chance to finish their unit, the construction of which began only in January 2011. All activity at the site has ceased since the March 2011 Fukushima nuclear meltdown.
TEPCO’s survey, scheduled for completion by 2020, will check the fault structure under the site using a two-kilometer-long tunnel, Kobayakawa said on Friday. Previous studies of terrain beneath the area by the Nuclear Regulation Authority (NRA) found the likely presence of multiple active, seismogenic faults. However, both TEPCO and the Tohoku Electric Power Company decided to conduct further ‘independent’ investigations to review the validity of the NRA findings.
The energy company wants to build two reactors at the site and is exploring ways to meet the stricter government regulations introduced following the Fukushima disaster. Higashidori units, however, would still use the same type of boiling-water, light-water reactors that suffered meltdown at the Fukushima plant, Japan Times noted.
“As we restart the (Higashidori) project, I want to make sure that a new plant would excel in safety,” Kobayakawa told a press conference. “The geological survey is a very significant step to move forward on the joint development of Higashidori,” he noted, adding that TEPCO has asked major utility companies in the country to contribute to the construction and operation of the Higashidori plant.
Three of the Fukushima plant’s six reactors were hit by meltdowns in 2011, after a 9.0-magnitude earthquake and subsequent tsunami struck the facility, resulting in the world’s worst nuclear disaster since Chernobyl in 1986.
Fuel removal from Fukushima reactor may be delayed
June 29, 2018
The operator of the damaged Fukushima Daiichi nuclear power plant says work to remove spent nuclear fuel from a cooling pool at one of its reactors may be delayed.
A total of 566 fuel units remain in the cooling pool at the No.3 reactor, which suffered a meltdown in 2011. Tokyo Electric Power Company, or TEPCO, planned to start removing the fuel as early as this autumn, as part of the decommissioning of the nuclear complex.
But on Thursday, TEPCO revealed the control board of a crane used in the removal malfunctioned during a test run last month. It blamed a voltage error and said the board will be replaced.
The company said the test run may be delayed by one or 2 months, pushing back the start date for fuel removal.
TEPCO’s chief decommissioning officer, Akira Ono, says he takes the glitch seriously as it shows key equipment was not handled properly.
He says that although safety must come first, his team still aims to stick to the original timetable and start the removal of nuclear fuel by around the middle of the current fiscal year, which ends in March next year.
Mayor of Namie, near shuttered Fukushima nuclear plant, dies at 69
Jun 27, 2018
FUKUSHIMA – Tamotsu Baba, mayor of Namie in Fukushima Prefecture, died at hospital in the city of Fukushima on Wednesday. He was 69.
First elected mayor of Namie in 2007, Baba was in his third term. He submitted his resignation earlier this month due to illness and was set to leave office on Saturday.
Baba spearheaded the town’s efforts to cope with the March 2011 earthquake and tsunami, which badly affected the Tohoku region, and the subsequent nuclear accident at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 plant.
Namie is located next to the towns of Okuma and Futaba, home to the disaster-crippled nuclear plant.
At the end of March last year, Baba decided on lifting evacuation advisories for Namie residents, except for areas that were recognized as heavily contaminated.
Shopping center opens in Naraha, a disaster-hit Fukushima town
Shopping center opens in disaster-hit Fukushima town as evacuees return
June 26, 2018
Iwaki – A new shopping complex opened Tuesday in the town of Naraha, Fukushima Prefecture, nearly three years after the government’s evacuation order following the 2011 nuclear disaster was lifted.
The public facility, dubbed “Kokonara Shotengai,” consists of 10 shops including a supermarket, a bakery and a barber’s shop.
The Chinese character meaning “laughter” was used as part of the name as a way to encourage and inspire returning residents.
The new shopping complex is adjacent to emergency public housing, a medical institution and a childcare center. It replaces a makeshift shopping district located elsewhere in the town.
Local residents welcomed the latest development in their hometown.
“I’m so glad that the opening day has come. I have been waiting for this for so long,” said 78-year-old Hisako Ishiyama, who, until March, lived in the city of Minamisoma.
Ishiyama previously had to travel by train or in her friend’s car to neighboring towns just to shop.
“Life will be easier,” she said after buying items such as a sliced raw tuna for dinner.
Evacuation orders and advisories were issued for some areas in Fukushima following the disaster. Naraha was the first on which the government lifted the evacuation order for a municipality whose entire population was ordered to evacuate in September 2015.
Most of Naraha lies within a 20-kilometer radius of the crippled nuclear plant, where three reactors experienced meltdowns after a massive earthquake and tsunami hit the eastern Japan in March 2011.
As of the end of May, 3,343 of 7,046 registered residents have returned to the town.
Fukushima town opens shopping center for returnees
June 26, 2018
The town of Naraha, Fukushima Prefecture, has opened a shopping center for the benefit of residents who have returned following the earthquake and nuclear crisis in 2011, and to encourage others to come home.
The area where the 3,300-square-meter complex is located includes public housing and medical institutions.
Ten businesses including a supermarket, hardware store and restaurants opened their doors on Tuesday.
The evacuation order in Naraha was lifted in September 2015. As of the end of May, nearly half the town’s former inhabitants had come back.
The town has begun operating free shuttle bus services between all its districts and the center to make life easier for those who return.
One woman said she’s happy that the center is accessible and that it will become a place where the townsfolk can socialize.
Evaluating Different Radiocesium Decontamination Practices In A Forest Plantation Near The Fukushima Nuclear Power Plant
June 25, 2018
Owing to an earthquake and the resulting tsunami that occurred on March 2011 in central-eastern Japan, the Fukushima Dai-ichi Nuclear Power Plant was damaged by several hydrogen explosions.
This accident released a vast amount of radionuclides, including caesium 134 and 137 (ca. ratio 1:1). Initial fallout contaminated cultivated soils (mainly paddy fields), forests, water bodies, residential areas, asphalt and concrete surfaces. Since then, a variety of decontamination practices have been completed, reducing the ambient dose rates.
In a recent study, published in Environmental Pollution (available online since April 19, 2018) and conducted by Prof. Yuichi Onda (University of Tsukuba, Japan), Dr. Manuel López-Vicente (EEAD-CSIC, Soil Management and Global Change Group), and staff of Onda’s Laboratory and Asia Air Survey Co., eight decontamination practices were evaluated in a forest plantation located 16 km southwest of the power plant and within the exclusion area. The stand is composed of a forest plantation of Japanese cedar (Cryptomeria japonica) and natural understory vegetation. This plantation has an age of 58 years (in 2017) and is located on a steep hillslope (average slope gradient of 25⁰) near Kawauchi village, in the Fukushima Prefecture. Ten runoff plots were installed and managed by the Fukushima Prefectural Forestry Research Centre.
Radiocesium (Cs-137) concentrations and activities were calculated in soil and litter samples over 27 months (May 2013 – July 2015) and after decontamination practices. One plot was devoted to litter removal; two plots to tree thinning without litter removal (Th_1 with logged area, and Th_2 under remnant trees); two plots to tree thinning with litter removal (Th + LR_1 with logged area, and Th + LR_2 under remnant trees); and three plots to clearcutting with litter removal (CC + LR_1 without matting, CC + LR_2 matting with seeds, and CC + LR_3 matting without seeds). Finally, two plots (Co_1 and Co_2) remained as control plots without application of any decontamination practice.
Differences were statistically significant, and researchers distinguished four homogeneous groups. Tree thinning and litter removal greatly reduced the radioactivity. Tree thinning, clearcutting with litter removal, and litter removal also had higher discharge rates than those rates in the control plots. We only observed low rates in the two plots with matting (soil conservation practice). The temporal variability was explained by (i) the different rainfall depths registered during the measurement intervals (with heavy rainfall events and typhoons: accumulated precipitation from 14 to 361 mm during the measurement intervals); and (ii) the fluctuations of the total ground coverage (canopy and surface).
The vegetation recovery after the countermeasures triggered a reduction of hydrological connectivity in all compartments of the forest plantation. This fact explained the decreasing trend in radiocesium concentration that was very high in 2013, high in the first half of 2014, moderate in the second half of 2014, and low in 2015. This tendency will reduce the possibility of secondary pollution of the neighboring residential and/or agricultural areas. The average proportions of the contribution of Cs-137 discharge by soil and leaf fraction were 96.6% and 3.4%.
These findings are described in the article entitled Radiocesium concentrations in soil and leaf after decontamination practices in a forest plantation highly polluted by the Fukushima accident, recently published in the journal Environmental Pollution. This work was conducted by Manuel López-Vicente, Yuichi Onda, Junko Takahashi, and Hiroaki Kato from the University of Tsukuba, and Shinya Chayama and Keigo Hisadome from Asia Air Survey Co.
This research was funded by the project “Development of techniques for migration control against radioactive substances in forests (2012-2016)” of the Japanese Forestry Agency; and was carried out by Dr. Manuel López-Vicente during his postdoctoral stays at the University of Tsukuba (Prof. Onda Laboratory) in 2015 (Research Fellowships Program of the Canon Foundation in Europe, call 2014) and 2016.
Japan touts completion of Fukushima cleanup at tripartite environment meeting in China
Lies, lies… and more lies!!!
Jun 24, 2018
SUZHOU – Environment Minister Masaharu Nakagawa told his counterparts from China and South Korea on Sunday that radioactive decontamination work following the 2011 Fukushima nuclear disaster is “all done” except for so-called difficult-to-return-to zones.
At the 20th Tripartite Environment Ministers’ Meeting held in Suzhou, in eastern China, Nakagawa also used the opportunity to again request the lifting of food import restrictions from prefectures hit by the Fukushima disaster.
Beijing has banned food imports from 10 prefectures surrounding the Fukushima No. 1 nuclear power plant, while Seoul has blocked Japanese seafood imports from eight prefectures.
Nakagawa explained to Chinese Ecology and Environment Minister Li Ganjie and South Korean Environment Minister Kim Eun-kyung that Japan has strict food safety standards in place that exceed international requirements. “Environmental regeneration in Fukushima is progressing steadily,” he said.
The three ministers also agreed on a policy to discuss the problem of plastic microparticles and their effect on marine pollution at a Group of 20 ministerial meeting on energy transitions and the global environment for sustainable growth in Karuizawa, Nagano Prefecture, next June.
In addition, they adopted a joint statement including a pledge to promote information sharing on the problem of venomous fire ants, which have over the past year repeatedly been brought to Japan in containers shipped from China.
The ministers also decided to hold next year’s tripartite meeting in Japan. It has been held annually in rotation among the three countries since 1999.
Japanese firms shift to clean energy despite state’s cling to nuclear power

June 2, 2018
TOKYO – While Japan’s government clings to atomic power even after the Fukushima nuclear crisis, its private sector is moving ahead with more use of renewables to power their operations amid growing international awareness of global warming.
Daiwa House Industries Co, for instance, became in March a member of both RE100 (Renewable Electricity) and EP100 (Energy Productivity), two global initiatives by the Climate Group.
RE100 is a global, collaborative initiative of influential businesses committed to using 100 percent renewable electricity, while EP100 brings together companies committed to doubling energy productivity to lower greenhouse gas emissions.
Among RE100’s 136 members are U.S. General Motors Co and Dutch consumer goods giant Unilever.
Printer maker Ricoh Co, the first Japanese firm to join RE100, was followed by five firms such as online stationery retailer Askul Corp and retail giant Aeon Co., aiming to meet the electricity needs of their global operations with renewable energy between 2030 and 2050.
Daiwa House says it is the world’s first company in the construction and housing sectors to join both campaigns and the first to declare it is taking bold action as part of EP100 among Japanese firms. Currently, there are 15 EP members. Daiwa aims to achieve the both by 2040.
Katsuhiro Koyama, general manager of Daiwa’s environment department, spurred debate to achieve the targets after returning to Japan from the COP23 global climate round in Germany last November.
He had previously taken a cynical view of such tech giants as Apple Inc, Google Inc and Microsoft Corp participating in the RE100 clean energy initiative, seeing it as an “atonement for their sins” of consuming huge amounts of electricity.
But Koyama, one of the Japanese delegate members to the global conference, said he was “inspired” by the firms’ “serious aspirations to leverage clean energy producers” after hearing various discussions.
The Osaka-based Daiwa group has invested an estimated 46.6 billion yen (about $424 million) in the construction of its own solar, hydro and wind power plants nationwide since 2007, producing power equivalent to about 60 percent of the group’s annual use of 481 million kilowatt hours. Meanwhile, it doubled its electricity use efficiency in fiscal 2016 compared to fiscal 2005.
Japanese businesses became much more aware of renewable energy in the wake of the Hokkaido Toyako summit in 2008 in which the Group of Eight countries set a long-term target to reduce greenhouse gas emissions.
The 2011 Great East Japan Earthquake, which triggered the suspension of all nuclear power plants in Japan, also sparked public concerns over the country’s energy mix.
The ratio of renewable energy to the nation’s entire power output capacity has risen from 10 percent in fiscal 2010 to 15 percent in fiscal 2016, according to the Agency for Natural Resources and Energy, boosted by a feed-in tariff system that obliges utilities to buy electricity generated by renewable energy at fixed prices.
The scheme has attracted businesses large and small, even individuals, to pour money into the photovoltaic field as it requires less effort to install and operate in a shorter period of time compared to other types of energy sources, said Yushi Inoue, a research director at Mitsubishi Research Institute, a think tank.
Individual power producers are actively trying to connect with grids in northeastern Japan, and sought to supply “more than three times what we can accept” in a recent offering, said a spokesman of Tohoku-Electric Power Co, the regional utility.
The region, part of which was devastated by the mega quake seven years ago and the subsequent nuclear disaster, has a number of favorable locations for wind power plants. “A vast majority of the seekers are renewable-energy oriented,” he said.
Meanwhile, a similar scheme in Europe that utilizes renewable energy certificates under a guarantee of origin of electricity generated from such sources has gained momentum among environmentally conscious firms, particularly after the 2008 summit on Japan’s northernmost island.
The tradable green certificate proves “environmental added value” created by renewable energy producers and can be purchased by electricity users.
Despite the financial burden, Ajinomoto Co switched its energy source to renewable energy for its entire annual electricity use of 4.5 million kilowatt hours at the Tokyo headquarters and major sales bases at home in the business year to March 2018.
Japan’s major seasoning and food maker extended the move to its four group arms in April, aiming to boost its renewable energy use to 50 percent of the group’s total energy consumption by fiscal 2030.
The targeted figure is part of various non-financial targets compiled for the first time in its three-year business management plan that started in fiscal 2017, said Mototsugu Shiratsuchi, general manager of the environment management support group of Ajinomoto.
Although the size of renewable energy certified is fairly small relative to the entire clean energy output in Japan, it has been steadily on the rise, reaching 378 million kilowatt hours in the year to March 2018, according to the Japan Quality Assurance Organization, the accreditation body.
Japan Natural Energy Co, the leading certificate issuer, has over 150 firms as long-term clients, such as Sony Corp and Asahi Breweries Ltd, and about 300 customers on a one-time contract basis.
The company is the pioneer in the field with about an 80 percent market share, according to the accreditation body.
President Masaru Terakoshi said that one of Japan’s global carmakers employed the certificate as part of its corporate social responsibility policy for 15 years but terminated a contract with the issuer two years ago.
The automaker, however, is set to repurchase the warrant this year following re-examination of how it can apply the certificate to its production activity.
Terakoshi declined to specify which automaker but indicated how Japan’s multinational corporations are becoming more aware of taking leadership roles in the fight against climate change.
“Otherwise, companies face a risk of losing clients,” he said, as the most of the world backs the landmark Paris accord of effectively reducing net CO2 and other greenhouse gas emissions to zero in the second half of this century.
The tradable certificate is widely used. Some hotels, for example, buy the warrants to claim their banquets are sustained by clean energy.
The Ministry of Economy, Trade and Industry drafted the latest energy mix plan due to be finalized this summer, calling nuclear power “an important baseload energy source.” This stance appears to conflict with public opinion which shifted after the 2011 Fukushima disaster. In addition to public sentiment against nuclear power plants, the government’s tougher safety standards led to the shutdown of all the countries reactors.
In the fiscal year through March 2017, fossil fuels accounted for 83 percent of Japan’s electricity output capacity. Renewables are currently at 15 percent.
The ministry proposes nuclear power should account for 20-22 percent of the country’s power source and renewables 22-24 percent in 2030, which still lagged behind the equivalent figures of major European nations in 2015.
‘Green Lawn’: Pundit Suggests Fukushima Prefecture May Remain Without NPP
24 June, 2018
Following the Fukushima No. 1 nuclear power plant core meltdown, the Fukushima No. 2 plant, which survived the earthquake and tsunami in March 2011, may be decommissioned. The president of the Tokyo Electric Power Co. (TEPCO), Tomoaki Kobayakawa, announced this in an interview with the governor of Fukushima Prefecture, Masao Uchibori.
The statement that the company is considering this option was made for the first time the Janapese Times (Nihon Keizai) reported.
Before the accident, Fukushima No. 1, with its six power units with a total generation capacity of 4.7GW, was considered one of the 25 largest nuclear power plants in the world. While there are only four power units at Fukushima No. 2, they were all shut down after March 2011.
Although there were serious problems with the emergency cooling system after they were shut down, the temperature of the reactors and the situation at the nuclear power plant could be quickly brought under control. The emergency situation at the power plant was lifted on December 26, 2011. However, since then, it has not resumed work.
According to TEPCO estimates, the closure of the Fukushima No. 2 power plant will require approximately 280 billion yen. In addition, another 22 trillion yen will go to the ongoing cleanup of the Fukushima No. 1 plant.
Japanese media have reported that the company was forced to take such a radical step because of the concerns of residents of the prefecture and the demands of local authorities. The potential dangers caused by natural disasters on the Japanese islands were also taken into consideration.
Just this week, after an earthquake in Osaka, all the nuclear power plants located in relative proximity to the epicenter were inspected.
Expert Mikhail Rylov from the Center for Nuclear and Radiation Safety told Sputnik that it would be difficult to relaunch the Fukushima No. 2 plant.
“I think this is, first of all, a business issue. For several years the equipment at the NPP [nuclear power plant] hasn’t been in use, and if it worked, it was not in the normal operational mode. To restart the power plant after so many years is troublesome and time consuming. Having estimated the technical condition and residual life of the power units, the company realized that even after restarting the nuclear power plant, in a few years the resource will need to be extended. And this is a very expensive task, requiring considerable intellectual and monetary costs. Surely they also took into account the issues of infrastructure, logistics, potential natural disasters, highly qualified personnel, etc. Like other nuclear power plants in Japan, [they] have already been tired of inspections after the Fukushima No. 1 disaster.”
Mr. Rylov noted that the decommissioning of the power plant is the best option in the current situation despite the fact that dismantling the plant is also a hard process.
“It takes several years to dismantle a nuclear power plant to the state of a ‘brown lawn,’ when not only equipment that was not intended for further use, but all the radioactive waste is removed from the site. The site can be used for other purposes, including for the needs of nuclear energy. But to bring the site of the former nuclear power plant to the state of a ‘green lawn’ will take several decades. ‘Green Lawn’ is a complete dismantling of reactor facilities, buildings, and disposal of radioactive waste with the complete elimination of all traces of NPP activities. Ideally, the final stage of the decommissioning process of a reactor should be a ‘green lawn,’ which means it would be safe for a public park or to build a kindergarten. How far will the Japanese company go, it’s hard to say. After all, there was still no official notification about the closure of the station,” the expert concluded.
The No. 4 unit at the Genkai nuclear power plant in Saga Prefecture restarted operations last week after it met all the requirements imposed after the Fukushima No. 1 plant accident. It became the ninth nuclear reactor to be restarted after new tougher requirements were introduced. A demonstration was held against the resumption of operations and people demanded that the country’s energy policy be changed.

TEPCO to gauge radiation in reactor building
June 21, 2018
The operator of the crippled Fukushima Daiichi nuclear power plant intends to send a robot into the No.2 reactor building as early as next week to measure interior radiation levels in detail.
It is a key step toward removing all 615 nuclear fuel rod units that remain in a storage pool in the building, and eventually decommissioning the reactor.
The pool is located on the top floor of the building. The No.2 reactor experienced a meltdown after the major earthquake and tsunami that hit eastern Japan in 2011.
Tokyo Electric Power Company, or TEPCO, plans to transfer the fuel units to reduce the risks posed by possible earthquakes and other factors.
TEPCO needs to map radiation levels and other detailed conditions inside the building before retrieving the fuel units.
The utility on Thursday finished breaching a wall of the building to allow entry to a robot and heavy machinery. Work on the 5-meter wide and 7-meter high hole started last month.
TEPCO plans to send a robot fitted with a camera and a radiation measurement device through the opening as early as next week.
And TEPCO could start removing the fuel around fiscal 2023 based upon the survey results.
TEPCO also seeks to begin retrieving nuclear fuel from the No.1 reactor around fiscal 2023 and from the No.3 reactor as soon as this autumn. Both reactors had a meltdown following the natural disaster.
As Fukushima residents return, some see hope in nuclear tourism
Posters promoting fukushima sightseeing at the Fukushima prefectural government office in Fukushima city
June 21, 2018
FUKUSHIMA, Japan (Reuters) – On a cold day in February, Takuto Okamoto guided his first tour group to a sight few outsiders had witnessed in person: the construction cranes looming over Japan’s Fukushima Daiichi nuclear plant.
Seven years after a deadly tsunami ripped through the Tokyo Electric Power (9501.T) plant, Okamoto and other tour organisers are bringing curious sightseers to the region as residents who fled the nuclear catastrophe trickle back.
Many returnees hope tourism will help resuscitate their towns and ease radiation fears.
But some worry about drawing a line under a disaster whose impact will be felt far into the future. The cleanup, including the removal of melted uranium fuel, may take four decades and cost several billion U.S. dollars a year.
“The disaster happened and the issue now is how people rebuild their lives,” Okamoto said after his group stopped in Tomioka, 10 kilometres (6.21 miles) south of the nuclear plant. He wants to bring groups twice a week, compared with only twice a month now.
Electronic signs on the highway to Tomioka showed radiation around 100 times normal background levels, as Okamoto’s passengers peered out tour bus windows at the cranes poking above Fukushima Daiichi.
Tourists from Philippines and tour guide Takuto Okamoto, Futaba town, May 17 2018
“For me, it’s more for bragging rights, to be perfectly honest,” said Louie Ching, 33, a Filipino programmer. Ching, two other Filipinos and a Japanese man who visited Chernobyl last year each paid 23,000 yen ($208.75) for a day trip from Tokyo.
NAMIE
The group had earlier wandered around Namie, a town 4 kilometres north of the plant to which residents began returning last year after authorities lifted restrictions. So far, only about 700 of 21,000 people are back – a ratio similar to that of other ghost towns near the nuclear site.
Former residents Mitsuru Watanabe, 80, and his wife Rumeko, 79, have no plans to return. They were only in town to clear out their shuttered restaurant before it is demolished, and they chatted with tourists while they worked.
“We used to pull in around 100 million yen a year,” Mitsuru said as he invited the tourists inside. A 2011 calendar hung on the wall, and unfilled orders from the evacuation day remained on a whiteboard in the kitchen.
“We want people to come. They can go home and tell other people about us,” Mitsuru said among the dusty tables.
Okamoto’s group later visited the nearby coastline, where the tsunami killed hundreds of people. Abandoned rice paddies, a few derelict houses that withstood the wave and the gutted Ukedo elementary school are all that remain.
It’s here, behind a new sea wall at the edge of the restricted radiation zone, that Fukushima Prefecture plans to build a memorial park and 5,200-square-metre (56,000-square-foot) archive centre with video displays and exhibits about the quake, tsunami and nuclear calamity.
LURING TOURISTS
“It will be a starting point for visitors,” Kazuhiro Ono, the prefecture’s deputy director for tourism, said of the centre. The Japan Tourism Agency will fund the project, Ono added.
Ono wants tourists to come to Fukushima, particularly foreigners, who have so far steered clear. Overseas visitors spent more than 70 million days in Japan last year, triple the number in 2011. About 94,000 of those were in Fukushima.
Tokyo Electric will provide material for the archive, although the final budget for the project has yet to be finalised, he said.
“Some people have suggested a barbecue area or a promenade,” said Hidezo Sato, a former seed merchant in Namie who leads a residents’ group. A “1” sticker on the radiation metre around his neck identified him as being the first to return to the town.

“If people come to brag about getting close to the plant, that can’t be helped, but at least they’ll come,” Sato said. The archive will help ease radiation fears, he added.
SPECTACLE
Standing outside a farmhouse as workmen refurbished it so her family could return, Mayumi Matsumoto, 54, said she was uneasy about the park and archive.
“We haven’t gotten to the bottom of what happened at the plant, and now is not the time,” she said.
Matsumoto had come back for a day to host a rice-planting event for about 40 university students. Later they toured Namie on two buses, including a stop at scaffolding near the planned memorial park site to view Fukushima Daiichi’s cranes.
Matsumoto described her feelings toward Tokyo Electric as “complicated,” because it is responsible for the disaster but also helped her family cope its aftermath. One of her sons works for the utility and has faced abuse from angry locals, she added.
“It’s good that people want to come to Namie, but not if they just want to get close to the nuclear plant. I don’t want it to become a spectacle,” Matsumoto said.
Okamoto is not the only guide offering tours in the area, although visits of any kind remain rare. He said he hoped his clients would come away with more than a few photographs.
“If people can see for themselves the damage caused by tsunami and nuclear plant, they will understand that we need to stop it from happening again,” said Okamoto, who attended university in a neighbouring prefecture. “So far, we haven’t come across any opposition from the local people.”

Fukushima Route 114 to Namie is No Route 66!
Even after lifting the ban on R114 last September, the route leading to Namie, a town near the Fukushima Daiichi nuclear plant, radiation remains very high.
