Determinants of attitudes toward nuclear power in Japan were assessed in a March 1999 survey. The results suggested that persons with interest in and knowledge about nuclear power judged its acceptability on the basis of their perceptions of the sufficiency of electric power and the risks of nuclear power, whereas persons with no interest in and knowledge of nuclear power did not respond on this basis. Although both types of respondents based acceptability on their trust in nuclear power operation and their perception of efficiency, the influence of perception of efficiency on acceptability was stronger for the interested and knowledgeable respondents than for the others. These results partially support the elaboration likelihood model or dual process theory.
