Steady efforts for recovery and reconstruction after the accident at the Fukushima Daiichi Nuclear Power Plant have been underway for 12.5 y. The present study reports on the world's first-ever efforts for a gradual and safe return to areas contaminated with radiation fallout and reconstruction support by providing an overview of the actual situation regarding the strategy for return, especially with the transition after the lifting of the evacuation order by the Japanese government. A stage-by-stage progression of the evacuation order and lifting strategy is summarized chronologically in the following three phases: the Emergency Phase in 2011, the Reconstruction Phase from 2013 to 2020, and the Challenging Phase for Lifting All the Evacuation Zones from 2023. Through the lifting strategy of the government, the number of evacuees decreased significantly, especially during the Reconstruction Phase, from 152,113 in May 2013 to 37,826 in May 2020. It is crucial to strengthen support for reconstruction and convey an unbiased and accurate understanding of Fukushima Prefecture by developing a concrete strategy for community development and increasing the size of the exchange population.

福岛第一核电站事故后，解除疏散令所涉及的持续稳定挑战。

福岛第一核电站事故恢复重建工作已持续12.5年。本研究报告了世界上首次为逐步安全返回受辐射污染地区和重建支持所做的努力，概述了返回战略的实际情况，特别是撤离解除后的过渡日本政府的命令。疏散令和解除策略的分阶段进展按时间顺序概括为以下三个阶段：2011年的紧急阶段、2013年至2020年的重建阶段和2023年起所有疏散区解除的挑战阶段。通过政府的解除策略，疏散人数大幅减少，特别是在重建阶段，从2013年5月的152,113人减少到2020年5月的37,826人。加强对重建的支持以及传达对福岛县的公正和准确的了解至关重要制定社区发展的具体战略并增加交流人口规模。
