福島第一原発から20km圏内は避難指示区域に指定され、住民の立入りが禁止されました。住民のの多くは緊急に避難したため、必要なものを持ち出すことが出来なく自宅への一時立入りへの強い要望があったことから、経済産業省が中心となって、住民の一時立入りのためのプロジェクトがスタートしました。2011年5月に始まった第1巡目から2013年5月の第4巡目までの一時立入りの概要について説明しています。
The area within a 20-km radius from the Fukushima Daiichi Nuclear Power Plant was designated as an evacuation area and the residents were not allowed to enter that area. Most of residents had to flee shortly after the nuclear accident, they could not bring their necessary belongings out with them at that time. For this reason, they strongly requested the public authorities for a temporary return to their homes. Following the request, the temporary entry project started. It was led mainly by the Ministry of Economy, Trade and Industry. From the 1st round conducted in May 2011 to the 4th round in May 2013 are introduced.
