On September 2002, it was found out that a Japanese electric power company had been concealing some defects of reactor-core-shroud for more than ten years. It was fortunate that the authors had been conducting a questionnaire survey immediately before this incident revealed, i.e., August, the survey being concerning risk perception, trust toward risk experts and administrative preference for them. We were also able to conduct a survey after this event, i.e., November, this enables us to examine the changes in attitude before and after this event. Participants of this panel survey were 200 people living in Tokyo Metropolitan area. The results indicated that trust toward the company itself and nuclear power plant system decreased, and that needs for government's monitoring and control over the electronic power companies were increased instead. It was also indicated that sincerity and trust had a crucial role for risk perception and need for control over risk experts.
