The final disposal of the soils removed from the area affected by the Fukushima nuclear accident will be carried out by 2045. This study investigated how acceptance of final disposal differed between top-down, opinion-aggregative, and opinion-reflective approaches to the decision outcome, and what factors influenced these differences. In 2022, a survey of 3000 randomly selected participants living outside Fukushima Prefecture was conducted using the postal method, with responses obtained from 871 consenting participants. The proportions of respondents who agreed to accept the final disposal were 22.6, 37.6 and 56.9% for the top-down, opinion-aggregative, and opinion-reflective approaches, respectively. The preferences for both opinion-aggregative and opinion-reflective approaches showed significant positive associations with interest in final disposal and social benefits, and significant negative associations with intergenerational expectations and age. This study highlights the importance of procedural fairness in determining final disposal sites, and identifies factors that contribute to greater acceptance through this process.
受福岛核事故影响地区土壤的最终处置将在 2045 年完成。本研究调查了在决策结果方面，自上而下、意见聚合和意见反思方法对最终处置的接受程度有何不同，以及哪些因素影响了这些差异。2022 年，采用邮寄法对福岛县以外的 3000 名随机选定的参与者进行了调查，从同意参与的 871 名参与者中获得了回复。对于自上而下、意见聚合和意见反思方法，分别有 22.6%、37.6%和 56.9%的受访者表示同意接受最终处置。意见聚合和意见反思方法的偏好与对最终处置的兴趣和社会效益呈显著正相关，与代际期望和年龄呈显著负相关。本研究强调了在确定最终处置地点时程序公平的重要性，并确定了通过这一过程提高接受度的因素。
