Risk communication through "Yuki-kaki Dojo" (a training program for snow shoveling volunteer).

本研究旨在通过越后铲雪训练计划（ESTP），分析外部无经验支持者参与的减灾过程，为区域雪灾预防潜力建立改进方法。从2011年度开始的3个冬季，在3个都道府县的18个地点举办了13次面向初学者的ESTP和22次生命线讲习班。结果表明，ESP与外部支持一起工作，可以有效地提高居民的减灾安全意识。通过对当地居民和参与者的问卷调查，证实了与外部支持者的合作为抵抗带来了更好的安全条件。分析结果表明：4个地区的雪灾风险均超过可接受水平，且主要以降雪为主，人口密度、老龄化率等社会指标对雪灾风险的贡献很小。

The purpose of this study is to analyze the disaster mitigation process with participation of external inexperienced supporter through The Echigo Snow-shoveling Training Program (ESTP), to establish an improvement approach for regional snow-hazards prevention potential. During 3 winters from fiscal 2011, 13 times ESTP for beginner, 22 times ESTP of lifeline workshops were held in 18 locations in three Prefecture. It was shown that ESP is effective for residents to improve their safety awareness of disaster mitigation working with external supporter. From a questionnaire to local residents and participants, it is confirmed a cooperative work with external supporter bring better safety condition for resistance. The analysis of snow-hazards risk of heavy snowfall four prefectures is shown the risk level in almost all region exceed an acceptable limit, and the risk is mainly dominated snowfall and the social indicators such as population density or aging rate contribute very little.
