In this study, the results of surveys conducted over the past 30 years were analyzed. The surveys include continuous opinion polls conducted by seven organizations, those conducted by eight news media one year after the Fukushima Daiichi accident, and those conducted by INSS fourteen times from 1993 to December 2011. The results were as follows: (1) Negative opinions toward nuclear power generation (NPG) suggesting “abolition or reduction”, which used to be 20-30% over the past 30 years, increased to 70% from four to six months after the accident, when there was also much news about renewable energy. (2) Even after the accident, 60% regarded NPG as “inevitable”, but many opposed future replacement or new construction of NPG facilities. (3) After the accident, recognition of the usefulness of NPG and concerns about electric power shortages in the near future remained unchanged, while anxiety and distrust toward NPG increased significantly. When considering power generation options, people now tend to focus on accident risks. (4) Nevertheless, people are neither aware of various possible problems caused by reducing NPG nor willing to accept a significant increase in electricity rate caused by the shift to renewable energy.

In Japan the “Basic Resident Register (BRR) ” is often used for statistical random sampling in public opinion surveys. The objective of the present paper is to compare two types of area sampling methods, without using the BRR. The first one (RRM) is a random route method, and the second one (DRM) is a method based on a database for a digital residential map. As a result, the percentage of data collected in the case of RRM was very low;and in the case of DRM, there was an uneven distribution in terms of respondents' age (a higher percentage of older respondents). However, when this bias was corrected by according weight to the population proportion, no strong significant difference concerning answer distributions was found. In each survey, the same substantial changes were detected statistically, compared with a past survey data based on the BRR. The findings suggest that these sampling methods are useful when accompanied with a careful analysis in spite of the resulting problems.
