This report analyzes Japan’s preparations to evacuate and support internally displaced persons (IDPs) from Okinawa prefecture in the event of a Taiwan Strait contingency.
It finds three major weaknesses in current Government of Japan (GOJ) civil protection planning:
- unrealistic assumptions about political decision-making and crisis conditions;
- unclear and inconsistent evacuation destinations that undermine public trust and local preparedness; and
- planning that treats displacement as short-term despite the likelihood of prolonged evacuation.
Drawing on lessons from the March 11, 2011 Great East Japan Earthquake, tsunami, and Fukushima nuclear accident, the report argues that IDP policy should assume long-term displacement from the outset. It recommends early provision of long-term housing, needs-based support rather than rigid eligibility criteria, improved IDP registration and communication systems, closer cooperation with NGOs, and stronger local administrative capacity.
While focused on Japan, the findings also offer lessons for European governments planning for displacement caused by armed conflict, climate change, or natural disasters.
