Abstract: This article provides the fourth update on the Fukushima Daiichi accident, from December 1, 2011 to March 11, 2012. As the last update, it will close the series that constitutes the one-year historical record of the accident, focusing on the attainment of a stable shut-down cooling state at the stricken Fukushima Daiichi nuclear power station (NPS), although the recovery operation will continue for many years in the future. The contents of this last update deal particularly with the Mid-and-long-Term roadmap for debris disposal, the decontamination and decommissioning of the Fukushima Daiichi NPS, the issues of radioactive contamination and decontamination around the Fukushima Daiichi NPS, and four investigation committees’ interim reports on the Fukushima Daiichi accident, published by TEPCO, the government, the National Diet and an independent body respectively. Furthermore, specific effects of the Fukushima Daiichi accident on international collaboration will be summarized at the end of this article.
