Problems in the shelter's life
Among critical infrastructure, water takes the most time to recover after disasters.
However, disaster-preparedness of water is still very insufficient in Japan.
Showers are especially important for public health and sanitation. Although its importance is highlighted in the "Evacuation Center Operation Guidelines" by the Cabinet Office of Japan and listed as the No.1 issue in the disaster rescue record by the Japanese Red Cross, no one has had the capacity to provide such services except for limited actors such as the Self-Defense Force.
