Following the accident at the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station (the Fukushima nuclear accident), environmental contamination by radioactive materials has become an issue in Fukushima, and large-scale decontamination has been carried out under the slogan "No recovery of Fukushima without decontamination". Most of the areas preparing for the lifting of evacuation orders and restricted areas have been lifted, and consideration is now being given to lifting the remaining difficult-to-return areas. Now, nine years after the accident, the relationship between decontamination and reconstruction in Fukushima is about to be reconsidered.

　東京電力福島第一原子力発電所の事故(福島原発事故)を受け，放射性物質による環境汚染が課題となった福島では，｢除染なくして，福島の復興無し｣をスローガンに，大規模な除染が進められてきた。大部分の避難指示解除準備区域，居住制限区域が解除され，残る帰還困難区域の解除に向けて検討が進んでいる。事故から9年が経過した現在，福島における除染と復興の関係性が見直されようとしている。
