For most of Japan, especially its major cities, the issues of how effective Prime Minister Shinzo Abe and his ruling coalition's economic policies have been and whether to restart the nation's idled nuclear reactors are generally treated by politicians and the media as separate debates.

In Fukui, home to 13 of Japan's 48 operational reactors, the largest concentration in the nation, the two issues are intimately connected in a prefecture that is one of the most conservative in the country, and one where Abe's ruling Liberal Democratic Party dominates.

Under a redistricting change, this election marks the first time that the prefecture will have only two single-seat districts, down from three. Six candidates are running for a seat in the two districts.
