A candidate backed by Prime Minister Shinzo Abe won Sunday's election for governor of Tokyo, frustrating a rival's efforts to make the vote a referendum on the Japanese leader's pro-nuclear energy policy nearly three years after the Fukushima disaster
The victory by former health minister Yoichi Masuzoe comes as a relief for Abe, who had suffered a rare setback in another local election last month.
The 65-year-old Masuzoe, backed by Abe's Liberal Democratic Party, won by a wide margin, according to media exit polls. Even before most votes were counted, Masuzoe's opponents conceded defeat.
The winner's most prominent rival was former Prime Minister Morihiro Hosokawa, 76, who came out of retirement to run and — with support from charismatic ex-premier Junichiro Koizumi — had put opposition to atomic energy at the core of his platform in the race to lead the capital city of 13.3 million people.
Hosokawa came in a close third after lawyer Kenji Utsunomiya, who also opposes nuclear power, NHK public TV said.
A half-hour before the polls closed, turnout was a mere 34 percent, well below recent polls, the broadcaster said. Some observers suggested that a record amount of snowfall may have kept voters home.
"I will make Tokyo the world's number one city," Masuzoe told supporters. "I want to work on social welfare, disaster preparedness, the economy and especially to make the Tokyo 2020 Olympics a success."
Masuzoe did not make energy policy a prime focus of his campaign, although he said Japan should reduce its dependence on nuclear power in the medium to long term. After his victory was announced, he reiterated that stance, adding he wanted to raise the share of renewable energy sources in Tokyo's electricity supply.
Public trust in nuclear energy in Japan was battered by the March 2011 disaster at Tokyo Electric Power Co. Inc's (TEPCO) Fukushima nuclear power plant north of Tokyo, triggered by an earthquake and tsunami. It was the world's worst nuclear accident since Chernobyl in 1986.
Surveys have shown that most Japanese voters favor abandoning nuclear power, either immediately or in the longer term, but they also indicate that energy policy is not as important an issue for voters as jobs and the economy, an ageing population and welfare.
Masuzoe's win is unlikely to mean smooth sailing for Abe's efforts to restart reactors shut down after the Fukushima accident. This is because of delays in safety checks by a new atomic regulator and the need to persuade host communities to agree to the government's plans.
Hosokawa opposed Abe's plans to make nuclear power a core source of energy and to restart the reactors.
Addressing supporters, Hosokawa said he felt there was a gap between the results and the enthusiasm he felt on the campaign trail.
"I am very sorry that my efforts were insufficient and that I could not meet the expectations of those who supported me so earnestly," he said.
