　Specifically, we focus that the number of polls in the coastal areas of the three prefectures has been decreasing, we analyze whether the number of polls in the coastal areas of the three prefectures was reduced in the election after the earthquake.

　The result shows that the number of polls in the coastal areas of the three prefectures was reduced by multiple regression analysis using control variables indicates other factors of declining the number of polls (local government population, finance and municipal mergers). Especially, it is clarified that the number of polls in the municipality which became the evacuation area by the accident at the Fukushima Daiichi nuclear power plant was decreased greatly.
