For Prime Minister Shinzo Abe, the two biggest election-defining issues of Sunday's Lower House poll are how to spend the additional revenue from the planned consumption tax hike in 2019 and how to deal with North Korea's nuclear threat. Leaders from other parties see either proposing or preventing revisions to the Constitution as their main priority.

But for residents of Fukushima Prefecture — many of whom are still recovering from the March 2011 Great East Japan Earthquake and ensuing tsunami that triggered a nuclear disaster — the focus is on when their lives will return to some semblance of normalcy.

That sentiment is strongest in the Fukushima No. 5 electoral district, site of the crippled Fukushima No. 1 nuclear power plant, which forced many to evacuate from the no-go zone more than six years ago.
