<p>Following the Great East Japan Earthquake, the contribution of geography was discussed from the viewpoint of delivering relief supplies after widespread disasters. Possible emergencies, obstacles, and counterplans were analyzed with the Nankai megathrust earthquake in mind. The Pacific coast of southeastern Japan, especially the Kii Peninsula, southern Shikoku, and eastern Kyushu, was an area significantly affected by the earthquake. The area was characterized by an aging population, little public transport, and poor transportation infrastructure. In addition, with the declining self-sufficiency of rural life, many commodities, including foodstuffs, consumed by rural residents are supplied from urban areas. In this current situation in Japan, delays and bottlenecks in the delivery of supplies to disaster-hit areas could cause major disruptions in relief activities. Therefore, rapid, effective relief transport systems and emergency stock systems are needed to reduce the damage. However, comprehensive approaches to these aspects lag behind in comparison with disaster-prevention measures and disaster-recovery assistance.</p>
