10-year Investigation Commission on the Fukushima Nuclear Accident

Project Outline

In March 2021, Japan reached the 10-year anniversary of the Fukushima nuclear accident. During this last decade, what has Japan learned from this unprecedented disaster in Japan’s post-war history? How has the “shape of the nation” changed for Japan itself? In inheriting the philosophy of the 2011 Independent Investigation Commission on the Fukushima Nuclear Accident, Asia Pacific Initiative (API) launched the “10-year Investigation Commission on the Fukushima Nuclear Accident (Second Independent Investigation Commission)” in June 2019, and published the results of the investigation in February 2021 (in Japanese first).

In an attempt to identify what the Japanese government and society have learned (or have not learned) in the last 10 years, the commission conducted a number of interviews with experts and practitioners in respective fields. The investigation covered issues that were suggested by various investigation committees, including the national diet, the government, and independent committees. These issues included: the government’s nuclear safety policy and nuclear disaster prevention, governance of power companies such as TEPCO, crisis management of the Cabinet secretariat office, communications risk management in the event of rumors or false information spreading, and cooperation with Japan’s Self Defense Forces, local police and fire departments. The investigation also examined the issues that have emerged over time, such as the decommissioning of nuclear power plants and reconstruction of the local community.

With the emergence of the COVID-19 pandemic from 2020, we have again seen an urgency to improve crisis management on both local and national levels. This is relevant not only to Japan but also worldwide as nations need to reconsider ways of governance and public policies amid national crises. API believes that it is our duty as an institution to thoroughly investigate the lessons learned from past major events and share these lessons to Japan and the rest of the world.

Project Approach

In this project, the investigation committee co-authored and published a report on the lessons learned and challenges faced in the 10-years after the Fukushima Nuclear Disaster.These challenges have been organized into seven different themes. The project was chaired by SUZUKI Kazuto, Professor of Tokyo University Graduate School of Public Policy and edited by API Chairman, FUNABASHI Yoichi.

The Evacuation of Hospitals in the Fukushima Sheltering Zone

In order to assess the challenges of and to draw lessons from the Fukushima nuclear accident before memories fade with the passage of time, this project investigated the medical system and evacuation of hospitals during the crisis. The project conducted interviews surveying six hospitals, pharmacies, elder facilities, and administrative agencies, all located within the sheltering zone, a 20-30km area from TEPCO’s Fukushima Daiichi Nuclear Power Station. This area was where people were forced to discern the risks of both radiation exposure and evacuating for crisis response at the time of the accident. During the one-year field investigation, the project members conducted detailed interviews with hospital directors and staff, as well as those who worked for local governmental agencies about what kinds of challenges hospitals faced at the time, how they tried to overcome them, and what lessons they learned.
