Before October 16, Ryuichi Yoneyama had contested four regional elections and been soundly beaten each time. Now, however, the 49-year-old qualified doctor and lawyer is to be sworn in as governor of Niigata Prefecture after defeating a candidate who had the backing of the ruling Liberal Democratic Party (LDP) and was considered the firm favorite.

Yoneyama worked hard for his victory over Tamio Mori, a former bureaucrat with the construction ministry, but when the voters stepped into the voting booths there was a single issue that occupied their minds.

Mori and the LDP want to restart the world's largest nuclear power station, the sprawling Kashiwazaki-Kariwa plant, which lies on the prefecture's coast. They insist that as Japan moves towards the sixth anniversary of the March 2011 earthquake and tsunami that crippled the Fukushima Dai-Ichi nuclear plant, triggering the second-worst nuclear crisis in history, new safety measures have been implemented that ensure the same thing could not happen in Niigata.

The voters did not agree, with 528,455 supporting Yoneyama's pledge to not grant approval for Tokyo Electric Power Co.'s (TEPCO) Kashiwazaki-Kariwa plant to be restarted. In comparison, 465,044 voted for Mori.

Nationwide opposition

Those figures are broadly replicated across Japan, with a poll conducted by the Asahi Shimbun newspaper on October 15 and 16 determining that 57 percent of the public is against the nation's nuclear power plants being restarted, and just 29 percent supporting the resumption of reactors that have nearly all been mothballed since 2011.

At present, only two of the nation's 54 reactors have been restarted - and that after much wrangling through the courts after local residents and environmental groups expressed their opposition.

Nevertheless, a report issued by the Institute of Energy Economics, Japan (IEEJ) in July predicts that seven additional reactors will be on-line by the end of March next year and a further 12 will be operational one year later.

But as the opinion polls show, the majority of the public is against a policy that the government tells them is in the nation's best interests.

"Since the accident at Fukushima, many people have realized the negatives that go along with the positives of nuclear power, and they simply do not want to take that sort of risk again," said Hiroko Moriwaki, a librarian who lives in Tokyo.

"And many think that we do not need to," she added. "Since the disaster, the reactors have not been operational and look around you; we have all the electricity that we need, there are no blackouts and everything is normal.

"Just after the earthquake, we were told to do everything we could to save energy, but not any more," Moriwaki told DW.

"So maybe we have reached the point where we don't actually need nuclear energy and that this is in fact an opportunity that the country can take advantage of," she said.

Japan is an advanced and industrialized nation with vast amounts of skills and technologies that could be put to use to develop and then commercialize new sources of safe, environment-friendly energy, she said.

As well as solar and wind power, which are already visible across Japan, there are moves afoot to harness Japan's tidal and wave energy, while vast amounts of potential geothermal energy remain virtually untapped.

"We have so much technology, so wouldn't it be best to divert some of that away from more investment in nuclear energy and put it into fuel sources that are safer and do not harm the environment at all?" Moriwaki asked.

Japan's energy needs

Critics of this approach - of which the government is one - say Japanese industry needs a secure supply of energy right now and that Japan is presently importing 84 percent of its energy needs, primarily in the form of coal, gas and oil. And that is both expensive and to blame for the nation's emissions of carbon dioxide and other harmful greenhouse gases climbing.

Still, the Japanese public is far from convinced that nuclear energy is the answer.

"It's complicated and we keep hearing from the government how important it is to have the nuclear plants operating again, but after Fukushima, I think, a lot of people no longer trust the operators or the government," said Kanako Hosomura, a housewife whose family home is north of Tokyo and only about 250 km from the Fukushima plant.

Inquiries after the disaster revealed that TEPCO ignored experts' warnings about the potential size and power of tsunami and had failed to take precautions such as ensuring a backup power supply in the event the generators used to cool the reactors were out of operation.

The government also came under fire after the media reported that it did not have a full understanding of the severity of the crisis, while it was also issuing statements that the situation was completely under control at the same time as drawing up plans to evacuate tens of millions of people from a huge swathe of eastern Japan.

"When it comes down to it, I have a young son and a family and their safety is my number one priority," said Hosomura. "Maybe Japan was lucky the Fukushima disaster was not worse than it was. Maybe next time we will not be so lucky."
