The Great East Japan Earthquake hit a large number of prefectures and cities in eastern Japan. Devastating damage was particularly heavy in Iwate, Miyagi and Fukushima Prefectures compared with other prefectures. Rescue operations were undertaken on a national scale. This experience of a great disaster hitting multiple numbers of prefectures is unprecedented in Japanese history and a number of problems therefore emerged. In the near future, major earthquake with epicenters in the Tokai, Tonankai, and Nankai regions are predicted to occur. The focal region of the Great East Japan Earthquake is similar to the scale of the focal region of these three earthquakes. In this paper, we are therefore proposing effective use of relief helicopters in large-scale expansive disaster based on the assumption that the three earthquakes have occurred.
