Numerous scholars and researchers have long advocated for citizen engagement in post-disaster recovery and reconstruction initiatives, although unique opportunities and challenges in effectively implementing citizen engagement still exist. It has been 12 years since the Great East Japan Earthquake, where the government called for a citizen-centered recovery and reconstruction process, and reconstruction in most areas in the Tohoku region has almost been concluded. Using qualitative data acquired through interviews with the residents, field observations during the World Bosai Walk, and questionnaire and archival research, this study aimed to discuss the overall reconstruction of Unosumai in Iwate Prefecture, giving the residents’ perspective on the benefits and challenges they faced in participating in recovery planning and reconstruction and how the community has been able to strengthen their participation in disaster reduction initiatives since the earthquake and tsunami. This discussion is crucial as it would effectively offer lessons on engaging residents in post-disaster recovery and reconstruction after mega-disasters.

尽管有效实施公民参与仍然存在独特的机遇和挑战，但许多学者和研究人员长期以来一直主张公民参与灾后恢复和重建举措。东日本大地震已过去12年，政府呼吁开展以民众为中心的恢复重建进程，东北地区大部分地区的重建工作已基本完成。本研究利用通过居民访谈、世界防灾步行期间的实地观察、问卷调查和档案研究获得的定性数据，旨在讨论岩手县宇野沼的整体重建工作，让居民了解他们面临的好处和挑战参与恢复规划和重建以及自地震和海啸以来社区如何能够加强对减灾举措的参与。这次讨论至关重要，因为它将有效地为居民参与特大灾难后的灾后恢复和重建提供经验教训。
