After the Fukushima nuclear accident, we examined changes in risk perception regarding the radiation contamination of food and information-seeking behavior among residents of three regions progressively more distant from the disaster area, the Tokyo Metropolitan area to the Kansai area. We conducted a ten-wave panel survey and obtained data from 1,752 citizens six months to nine years after the accident. The results indicate that anxiety related to radioactive contamination, active information-seeking behavior, and avoidance of foods from affected areas decreased with time. Active information-seeking behavior and radiation-related knowledge were higher in the disaster-affected prefectures than in other areas. Conversely, avoidance of foods from affected areas was lower in affected prefectures than in the Kansai area. The credibility of government information increased from a considerably low level but did not reach the midpoint level. Multiple regression analysis, cross-lagged analysis, and structural equation modeling indicated that avoidance of foods from affected areas was promoted by anxiety related to radioactive contamination (experiential thinking/System 1) and inhibited by critical thinking attitudes (analytical thinking/System 2). Finally, we discussed the significance of risk literacy, which integrates risk-related knowledge, scientific literacy, media literacy, and critical thinking.
